What Is Server Side Rendering: Definition, Benefits, and Risks


When you are going to create a new web solution from scratch or optimize an existing one, one of the key indicators of top high quality will most likely be a high response rate (to user actions) and SEO-friendliness.
Unfortunately, client-side rendering, which is done by default in many modern web frameworks and libraries, can become an antagonist for developers pursuing these two goals. In this case, it makes sense to consider the possibility of implementing server-side rendering. Below, we will explain to you what it is, what its features are, with the help of which software tools it can be implemented, and also for which projects it is best suited.
Definition of Server-Side Rendering
Generally speaking, server-side rendering (SSR), as is probably clear from the name, occurs on the backend side. First, the browser sends a request from the client side to the server, after which the SSR server returns an HTML page with all the necessary meta tags, styles, markup, and other attributes. Then, in the browser, the rendering itself happens, the results of which immediately become visible to the end user.
Why is all this necessary if you can use the default option, client-side rendering (CSR)? – you may ask. In fact, everything is simple: search engine crawlers do not recognize the SEO text contained on the pages (or the page, if it is the only one) of the CSR solution. Thus, if the CEO occupies a significant part of the promotion strategy of your project, you can achieve better results only by implementing SSR. Let us add that projects with sophisticated business logic may “suffer” from CSR in the context of performance since the increased load in the form of several synchronous requests will lead to delays in the interface’s response to user actions. And this is exactly the case where server-side rendering can also become a win-win solution.
Currently, SSR technology is actively used in such world-famous solutions as Airbnb, Upwork, YouTube, Netflix, Uber, etc.
What Are the Benefits of Server-Side Rendering?
Now, based on the above, let's look at the key benefits of SSR.
- SEO and social media friendliness. The server side render approach ensures improved SEO ranking through the correct indexing of pages – now, search robots can recognize SEO text and other attributes important for good ranking. First of all, this is due to the fact that now, search robots do not need to read SSR JavaScript code. As for friendliness for social platforms, it is explained by the ability to display colorful previews when sharing SSR-rendered pages – all due to the correct recognition of meta tags.
- Better app/website performance. SSR rendering provides a faster initial page load as the JS to HTML conversion is done on the backend. Thus, users see refreshed content faster than with CSR, in particular when it comes to dynamically updated pages. In the long term, this can ensure a reduced bounce rate for websites and web applications.
- Lower load on the user's device and better user experience (UX). Due to the fact that user requests are now processed on the server side, the user device will experience minimal load. All that remains for it is to interpret the HTML code returned by the server.
What Are the Risks of Server-Side Rendering?
To ensure the objectivity of our review, let's also analyze the disadvantages of server-side rendering.
- Higher TTFB. TTFB or time to the first byte is one of the highest priority indicators of good (or, vice versa, insufficient) performance of web pages. This parameter indicates the time it takes for the browser to receive the first byte of page data processed on the server side. Typically, compared to CSR, the TTFB value is higher because instead of returning a file with links to JS, the server spends some time converting JS to HTML code.
- Limits on the number of requests simultaneously processed on the server side. Due to the increased load on the server, the number of requests processed synchronously will be less than in the case of client-side rendering. Thus, the server throughput will be reduced.
- Need to wait for all the HTML code to load. While the page is loading HTML code under SSR, the user will not be able to perform any new actions on it.
If we add to the above disadvantages a fairly high entry threshold into SSR, as well as an increase in the budget of such projects (due to frequent requests to the server), it becomes clear that this approach is not suitable for everyone.
Server-Side Rendering Frameworks and Tools
As for the server side rendering frameworks and libraries that can be used to process client-side requests on the backend, these include React, Next.js, Nuxt.js, Angular (v7 and newer), and Svelte/Sapper. They use one of the most universal server-side templating languages – JavaScript.
Below we propose to consider server-side rendering React concepts only since React is one of the main tools that we use in web development.
Server-Side Rendering vs Client-Side Rendering
Server-side rendering is not a one-size-fits-all solution since there are situations where its alternative, client-side rendering, is the best choice. In particular, if the content on web pages is updated dynamically – that is, it requires the rendering of some components only (i.e., those with whom the user interacted) while the whole page doesn’t need to be updated, CSR is better suited since part of the content with which the user did not interact will be already loaded.
However, considering that during initial initialization, the content is not displayed until the page is fully loaded into the browser (this can take 2 or 3 seconds, which is critical for a modern consumer of Internet content), when implementing CSR, the site may have poor SEO regardless from the professionalism of SEO specialists (note that this is not a default situation, because with the right approach, lightweight projects with CSR are still ranked well). And this is where the SSR React approach can come to the rescue as usually, React server side components are well-recognized by search crawlers. Thus, by resorting to it, you will be able to ensure enhanced content visibility for search engines.
Server-Side Rendering: SEO vs. Performance
As you can already understand, server-side rendering is capable of providing the best SEO performance for solutions that really need it. In particular, thanks to this approach, search engines will not need to interpret JavaScript. At the same time, if you decide to render in React applying CSR by default, for the React server side rendering implementation, you will have to use additional tools to indicate metadata (for example, React Helmet).
As for performance, in the case of high-load projects, with the server side React rendering, this indicator will be better than with CSR since the SSR website or application will not be limited by the resources of the user device and browser. Also, the user device itself will be less loaded since its only task in the context of updating content will be its output (without rendering).
Conclusion
To sum up, we would like to emphasize that with the correct use of JavaScript frameworks for SSR, you can solve the problem of poor ranking of single-page applications (SPAs) as well as content-heavy websites where SEO and bootstrap performance are critical. On the other hand, CSR is suitable for software with dynamically updated content, that is, content that should change without completely refreshing the page.
However, you should not limit yourself to just these two rendering approaches. In particular, there are also hybrid rendering approaches that combine the best characteristics of SSR and CSR. For example, you can consider the static site generation (SSG) vs SSR couple – perhaps the first option will be the best choice for your project.
FAQ
In SSR, content is pre-rendered on the server and sent as HTML. In CSR, the browser loads JavaScript first, then generates the page, which can lead to slower initial loading times.
SSR improves SEO, delivers faster initial page load times, reduces the load on users’ devices, and enhances the overall user experience.
SSR can increase the time it takes for the server to send the first byte of data (TTFB), limits the number of simultaneous requests the server can handle, and may require higher costs due to increased server demand.
No, SSR is not ideal for all projects. It’s best for sites where SEO and fast initial load times are priorities. If your app relies on dynamic content updates, client-side rendering (CSR) might be more efficient.

RPM monitoring software—is a digital tool for wearables, mobile apps, and medical devices that collects, analyzes, and shares patient data with medical personnel. Heart rate, blood sugar, and oxygen levels are among the most vital metrics. RPM software scores help catch health issues early, manage chronic conditions, and aid post-operative recovery.

How remote patient monitoring software works
From heart rate to blood glucose, each RPM system is designed to monitor a specific aspect of the body. However, elements included in any remote patient monitoring software development are typically the same. This is how the RPM system works:
- Collects and exchanges data.
Once calibrated, the devices send the data from the patient to the provider. The devices must have a Wi-Fi or LTE adapter for successful transfer. The data can also be sent via Bluetooth to IoT mobile apps via RPM devices. - Centralizes storage.
The provider securely stores the data collected from various sources, including patient devices, analytics systems, and e-medicine.
- Analyze.
The data is processed using advanced AI for management and analytics. Alerts are sent to caregivers, providers, and patients as needed, per their preferences. - Broadcasts.
Remote monitoring systems become telemedicine platforms when integrated with communication features like video conferencing, simplifying doctor-patient interaction.
- Sends emergency notifications.
When doctors identify health issues requiring daily monitoring, they oversee the data collected by the RPM system. Notably, it can notify emergency services if a patient needs urgent care. For non-urgent cases, patients can receive instructions for the next steps. However, HIPAA and similar regulations may restrict including sensitive patient information in certain notifications to protect privacy.
Why build remote patient monitoring software? Key advantages
Nevertheless, the RPM is part of the broader automation revolution; it has universal healthcare benefits overall. Let's examine the main of them:
Better access to health services
With remote patient monitoring software, medical services have no geographical boundaries. Patients can get timely medical attention at home and manage their health, fostering a greater sense of control under health conditions.
Improved patient outcomes
A study found that RPM cut hospital admissions for chronic care complications by 19% to 41%, which results in improved patient outcomes.
Cost-effective care with reduced readmissions
The average cost of hospital readmission is about $15,200, which makes the prevention of readmissions through remote patient monitoring software financially beneficial for both patients and providers. Even more, it is a well-established fact that early detection generally translates to lower healthcare costs.
Better client engagement and satisfaction
Over 94% of patients are satisfied with RPM's care. It sparks their curiosity about their health and boosts engagement. Such an increased sense of involvement often inspires commitment to treatment plans.
Early detection and timely intervention
The CDC reports that RPM can cut chronic disease complications by 40%. This highlights the need for swift intervention to reduce health risks.
Components of remote patient monitoring software
There is no one-fit RPM soft, as it differs in nature. However, each patient monitoring system generally has 3 to 5 basic components. Let’s delve into them:
Personal monitoring devices
From continuous glucose and heart rate monitors to blood pressure cuffs, digital scales, and peak flow meters.
Patient-side mobile applications
Prioritize user experience, making it easy for patients to access their health data. Additionally, they offer features like medication reminders and secure chats with healthcare providers.

These comprise decision support systems, reporting tools, notification systems, and analytics platforms.
Essential features in remote patient monitoring solutions
Here are the essential features of a remote patient monitoring (RPM) solution:
Real-time tracking of patient vital signs
Wearable sensors, fitness trackers, blood pressure monitors, and glucose meters perfectly gather and handle real-time health metrics. Then, this data is sent to healthcare providers and added to Electronic Health Records (EHRs) for timely interventions and informed decisions preventing complications.
Intuitive interfaces and user-friendly features
Machines must be easy to set up, a breeze to wear, and simple to operate. Meanwhile, patients should access their data effortlessly through a smooth web or mobile app to track their progress. This connection allows seamless communication with healthcare providers, ensuring everyone's on the same page.
Accessibility features
Ultimately, create a system with all users in mind. Consider accessibility guidelines like WCAG and CVAA to pave the way for inclusive innovation. Encompass voice control for effortless data entry, navigation, and text-to-speech features to support people with dyslexia and other disabilities. Moreover, a patient-first design shines with screen reader compatibility, high-contrast modes, and a crystal-clear interface.
Personalized risk alerts and reminders
For swift and customizable alerts, the RPM system must adjust thresholds. For example, alerts can be sent when vital signs fall outside preset limits. This enables timely intervention to reduce the risk of adverse events.
Safe data transmission and storage
Patient data security is a top priority in remote patient monitoring software development. Thus, apps must comply with all regulations like HIPAA, as they protect the privacy and security of patient data and save from hefty fines.
Smooth EHR integration
EHR integration allows the automatic transfer of RPM data, giving healthcare providers access to complete patient histories for better decision-making and outcomes.
Reports and analysis of patient health data
Advanced analytics and reporting in remote patient monitoring software development provide valuable data insights for healthcare professionals (for data-driven decisions) and patients (to motivate healthier choices).
The architecture of a remote patient monitoring system
Remote health monitoring systems are designed with a multi-layered architecture. Basically, it has five core components that enable uninterrupted data flow within the system. Let’s break into the point of the whole structure:

Smart-connected sensors for health tracking
The sensor layer comprises remote monitoring devices such as EKGs, sleep trackers, smartwatches, and blood pressure monitors. Then, they transmit this data to the dedicated mobile app via Bluetooth or to the cloud via the Internet.
Patient interface
Patient-facing RPM apps collect real-time health data from connected medical devices, allowing manual entry of symptoms and medication intake. RPM apps often include data visualizations for tracking health trends and may have integrated telemedicine features, such as video conferencing for appointments, follow-ups, prescriptions, and virtual consultations.
Cloud RPM server
Cloud services form the core of RPM systems, providing secure storage, processing, and data analysis from devices and the RPM app. This engine also integrates with EHR systems to access patient health information (PHI) in FHIR format. It can identify trends, such as early signs of complications.
Medical staff dashboard
Patient data flows bidirectionally between the medical staff interface and the cloud RPM server, enabling effective management by care teams.
- Data visualization module.
Via charts and graphs that show trends in vital signs, medication adherence, and other data, the module gives providers a 360-degree view of the patient. - Alert management module.
The system promptly alerts clinicians to critical situations and device failures in real-time. - Reporting module.
The module generates custom reports on patient data, which hugely help track progress and gain insights over time. - Communication module.
This module has two-way messaging, video chat, and/or telephony integration and is made for secure, remote communication between clinicians and patients. - Appointment management module.
This module handles appointment scheduling and patient-provider communication, allowing both patients and providers to request appointments.
Depending on the organization's needs, a doctor-facing RPM interface can include other modules, such as patient management, care plans, and patient education.
Admin web panel
A key part of the RPM architecture is a control dashboard. It helps with admin tasks like configuring roles, managing patients, and setting alarms.
Remote patient monitoring software development: Key steps
Once you have a clear idea for your software product, find an experienced dev company to implement it. When contacting your tech partner, you don't need detailed software requirements. A high-level understanding of the functionalities is enough to get started for any custom healthcare software development services stages. Let’s break them down:

Rising public interest, health concerns, and tech advances drive the RPM market to new heights in solutions and revenue. As we noted earlier, these technologies enable 24/7 health monitoring. They also provide remote populations with access to quality treatments.
Doctors, nurses, and other healthcare staff should focus less on routine, manual tasks in the next few years. They should focus on saving lives and providing treatment, which RPM can support perfectly. It can greatly reduce burnout and ease stress on global healthcare systems while driving market share to higher results and stakeholder benefits.
This is a great time if you're considering developing your RPM solution.

According to a recent Deloitte study, 76% of American companies outsource their IT functions. What drives this trend? Does outsourcing truly win the in-house vs outsourcing development battle? In this article, we will explore both strategies, evaluate their advantages and disadvantages, and help you choose the approach that best suits your project.

What Is In-House and Outsourcing Software Development?
In-house development refers to the process in which a company independently creates its digital products. In this case, only the internal team is involved in development, without hiring external specialists.
Do you think this approach is ideal because all IT functions will be handled by a reliable development team that you assemble yourself? In some ways, you’re right. However, it also comes with significant responsibility and high costs. After all, you will need to hire and manage developers, designers, product and project managers, and other personnel. But we will discuss the pros and cons of this strategy in more detail later.
Outsourcing software development implies hiring an external team or individual remote specialists to work on a software solution. Depending on the budget size, required technology stack, and other project specifics, you can choose between nearshoring, offshoring, and onshoring. What do these terms mean?
Offshoring refers to delegating processes to a distant country, often on another continent. This is considered the most cost-effective outsourcing option, as service rates vary significantly across countries. However, such price differences do not always affect the quality of the final product.
Take a look at these impressive figures: In Switzerland, developers earn around $100,000 per year, whereas in Norway, Australia, and several other countries, this amount is nearly half as much. Does this mean that specialists in those regions are less qualified? Hardly.

Nearshoring—outsourcing to a neighboring country. Preferably one that borders yours or is at least located on the same continent. The goal is usually the same—to save on IT services.
Onshoring—hiring external specialists from your own country. What is the point? It’s simple. Even within the same state, the cost of creating an identical digital solution can vary significantly.
As an example, take a look at the salary range in major USA cities (data provided by Indeed):
- Columbus, OH – $142,605 per year
- Bellevue, WA – $137,206 per year
- San Jose, CA – $120,751 per year
- San Diego, CA – $118,932 per year
- Houston, TX – $98,751 per year
So, we have figured out the definitions of in-house and outsourced software development and also discussed the types of the latter. What are the key differences between these strategies?
In-House vs Outsourcing: Key Differences
In-house vs outsourcing development is a choice that many teams face. The fact is that there are several fundamental differences between these approaches. They should be taken into account when organizing the development process in a company.

This comparison highlights the strengths and weaknesses of both approaches to software development. However, to make these differences even clearer, let's take a closer look at the pros and cons of outsourcing and in-house development.
Outsourcing Software Development: Pros and Cons
Let’s start by looking at outsourcing software development – the pros and cons of this approach allow the global outsourcing market to grow at an impressive rate. This suggests that the cons of this approach are not so significant, right?
If in 2024 it was valued at $611.8 billion, it is projected to grow to $1,345.5 billion in the next 10 years.

Outsourced Development Pros
Teams that opt for outsourcing digital solution development can expect the following benefits:
1. Cost Savings.
We’ve already mentioned that companies can save by outsourcing to regions with cheaper labor.
However, that’s not all. Toptal has created a calculator to estimate the actual costs of hiring in-house developers and remote specialists. According to the calculations, even with the same hourly rate, outsourcing will cost the company 1.5 times less:

This is explained by additional expenses for office rent, employee training, providing necessary infrastructure, and so on.
2. Access to the global talent pool.
Finding a developer with the necessary skills can be challenging, especially in regions where the number of specialists is not very large.
Take a look at how the number of IT specialists differs in various countries:

Access to the global talent pool allows you to use the latest technologies that may not be widely available in your region.
3. Flexibility and scalability.
According to Indeed, the hiring process can take anywhere from a week to a month or more! Therefore, if you anticipate the need to expand or reduce your team, it is wiser to consider outsourcing.
It also makes more sense to consider a remote candidate for short-term projects if there is no further collaboration planned after the project ends.
4. Accelerating Time to Market.
Outsourcing allows you to reduce the time spent on recruiting and hiring specialists. Additionally, there is no need for training and onboarding the development team, which, as you’d agree, is also a lengthy process.
Moreover, you can engage several teams to work on the project. They will work on different aspects of the application simultaneously, bringing its release closer. An additional benefit is the ability to work around the clock due to time zone differences.
5. Optimization of company operations.
Outsourcing IT functions will allow you to focus on other activities, such as marketing, customer service, implementing financial strategies, and more.
Furthermore, outsourcing makes sense even if you have an in-house development team. Engaging external specialists will reduce the load on your team and allow you to implement innovative technologies that your developers may not be proficient in.
Outsourced Development Cons
Along with the benefits for a company, turning to IT outsourcing can lead to certain challenges:
1. Communication problems.
This issue is especially relevant with offshoring, when specialists are located in different time zones. Just imagine: you need to urgently address an issue, but it's outside your team's working hours. This can seriously affect the efficiency of development.
Another possible barrier to productive collaboration is different languages and cultural differences. Wouldn't it be difficult to understand your counterpart if their vocabulary is unfamiliar to you, or if they adhere to values and traditions that differ from yours?
2. Quality control challenges.
When an in-house team is working on a software product, they are clearly aware of the standards they need to follow. This enables them to create solutions that meet the needs of the audience and business expectations.
In the case of outsourced development, there is a risk of discrepancies in quality standards between internal and external teams, especially when communication gaps exist.
The result is an unsatisfactory final product, which may lead to another outsourcing drawback—as we'll discuss next.
3. Hidden costs.
If the final product quality is lacking, you’ll have to hire other specialists to fix defects. However, this problem can be avoided by working only with trusted providers.
Still, there is the risk of additional costs for managing remote specialists and the possibility of project expansion due to control issues.
4. Data and intellectual property (IP) security.
Collaborating with third parties on development involves sharing confidential information about your business and clients.
Again, only work with reliable partners to ensure they won’t misuse your data or share it with unauthorized individuals.
We’ve discussed the pros and cons of outsourcing software development. How does the situation look with the advantages and disadvantages of creating an in-house team?
In-House Development: Pros and Cons
Despite the growing popularity of outsourcing, many companies still prefer to develop software in-house. This approach also has its own pros and cons.
In-house Development Pros
Developing software internally offers the following advantages:
1. Full control over the development process.
The decision to hire an in-house team is a step towards complete control over the development process.
You can select the optimal tech stack, implement methodologies that you deem suitable, and track every stage of the SDLC and its duration.
2. Intellectual property security.
According to ABI Research, U.S. companies lose between $180 billion and $540 billion annually due to intellectual property theft.
In-house development minimizes the likelihood of this issue, as the company will be the sole owner, and there is no need to share data with third parties.
3. Improved communication on the project.
Teams working in a shared workspace experience fewer communication challenges. They are not hindered by cultural and language differences or time zone discrepancies.
This, in turn, helps avoid several problems. According to recent statistics, poor communication methods can lead to a number of losses for a company. Among these, 68% of work time is wasted, 42% of employees face stress and burnout, and 12% of customers leave for competitors:

4. Team engagement and a deep understanding of business nuances.
An internal development team is likely to be better informed about the company's values, culture, and target audience. This enables them to create a tailored solution that aligns with the client’s vision.
Additionally, in-house developers are more invested in the success of the project, as they are part of the business.
In-house Development Cons
If you are an advocate of in-house development, be prepared for some challenges along with the benefits. Here are a few of them:
1. High costs.
With outsourcing, the company only spends money on the developer’s rate. The situation is completely different with an in-house team.
We present a list of expenses to consider:
- hiring costs;
- total salary of the team;
- provision of necessary infrastructure;
- training fees for technologies;
- bonuses and benefits;
- software license purchases;
- overhead costs.
Overall, the difference between in-house vs outsourcing development can amount to hundreds of thousands of dollars. And as you can see, it is not in favor of the in-house team.
2. Limited resources.
In-house specialists may have limited experience and knowledge in specific areas needed for the project. There are two solutions to this issue: employee training, which again incurs additional costs and time, or opting for familiar technologies that are unlikely to yield the desired results.
Moreover, the lack of resources may become noticeable when scaling the project significantly. Hiring an in-house specialist is a lengthy and complicated process.
3. Hiring issues and employee turnover.
According to Statista's analytics, in 2023, 54% of organizations experienced a shortage of tech talent. And this is not the peak — two years ago, this figure was at a record-high 70%.

However, even if you manage to hire the best talents, don’t rush to celebrate your victory. You still need to retain them. And here’s where the real challenge begins. To attract a developer to work specifically for your company, you will need to offer a high salary (higher than your competitors), social benefits, bonuses, etc. In other words, you will be committing yourself to unforeseen expenses. Whether this is justified is up to you to decide.
So, we’ve thoroughly discussed the advantages and disadvantages of in-house development and outsourcing. Now, it’s time to determine which strategy is best suited for you.
In-House vs Outsourcing: How to Make the Right Choice?
In-house vs outsourcing software development—which one should you choose for your company’s success? Here are the types of projects optimal for each of these strategies:
For in-house development:
- Long-term projects. If a project requires constant development, support, and close collaboration, it makes sense to build an internal team. This is especially relevant for complex systems that are continuously evolving and require in-depth knowledge of their architecture.
- Projects involving confidential data. If you are dealing with confidential data, in-house development can guarantee its complete security. This is facilitated by better control over work processes and the absence of the need to share data with third parties.
However, as an alternative, you can turn to a reliable outsourcing provider who guarantees the security of confidential data on par with an in-house team.
- Projects that are critical for the business. These are projects that involve creating products that must fully reflect the vision, culture, and strategy of the company. If you are not sure that you can achieve this with external developers, it is better to opt for an in-house team.
For outsourced development:
- Projects with a limited budget. Outsourcing allows savings on developer salaries and related expenses.
- Short-term projects. If the team is only required to create a product without further updates and support, hiring in-house specialists is not advisable.
- Projects where quick time-to-market is a priority. Time savings on hiring and adaptation, the ability for round-the-clock work, and involving multiple teams contribute to faster releases.
- Projects with changing resource needs. Here, the ability of remote teams to scale quickly is key.
- Innovative projects. Access to a global talent pool enables the use of cutting-edge technologies that may not be well-developed in your region.
Thus, if you are looking to save costs, use an innovative tech stack, and outpace competitors, outsourced development will be the best choice for your company.

From long patient wait times to inefficient manual processes and risky paper records, the healthcare sector has faced numerous challenges historically. This has created a fertile ground for doctor appointment apps. According to Verified Market Reports, in 2023 alone, the market was valued at an estimated $318.49M, projecting a surge to $862.16 million by 2030 (15.29% CAGR).
Given the growth of AI-based solutions in telemedicine tech and the modernization of the healthcare system, we can now highlight the importance of such solutions and dive deep into the specifics of healthcare appointment apps.
What is a doctor appointment system?
A doctor appointment application — is a digital solution that automates the registration of patients for an appointment with medical specialists. However, modern solutions imply more than just scheduling online appointments. They give patients useful information about a healthcare institution's services and specialists. Also, they connect patients with doctors and give access to their records in the comfort of their homes.

Why is this system gaining traction in the healthcare sector? Let’s break it down into factors:
- The widespread digitalization of the healthcare sector.
Healthcare is moving beyond in-person consultations in the facility. Now, it includes remote consultations, app-based therapies, and remote health tracking for timely interventions. - The development of modern technologies.
Various mobile applications and the affordability of smartphones make this format of interaction with patients desired and preferable. - Reducing the workload on administrators.
To prevent personnel burnout, medical institutions can use healthcare scheduling software systems to reduce the number of routine tasks assigned to administrators and the number of errors associated with the human factor. - Increased patient satisfaction.
Transparent access to doctors' schedules and the ability to choose a suitable time — increase customer loyalty. - Increased occupancy of doctors' schedules.
With a doctor appointment system, healthcare organizations can minimize empty appointment slots since it will be easier for patients to choose the optimal date and time for a visit.
Key doctor appointment app features
Since the Apple App Store boasts approximately 35,019 healthcare and medical apps, among which are approximately 10 to 20 types of doctor appointment apps, features might hugely range from app to app. Let's examine the main features of the doctor appointment app.
Online appointment booking
The system should have filters for doctors by specialization, review patient feedback, and book appointment availability by date and time. Additionally, patients should be able to receive reminders for upcoming appointments (e.g., push notifications, email, or SMS).
Telemedicine
For routine follow-ups, an online medical appointment system is essential. It's not a choice but an inevitability. Both patients and healthcare providers save travel time and can schedule appointments just in the app via online consultations, video conferencing, or text chat.
Integration with EMR and billing system
Integration with electronic health records provides access to the patient's medical data directly from the application, allowing doctors to update and review these records directly from the platform. As for the billing system, the PCI DSS-compliant payment gateway will be the core element of the online payment process. In addition, it provides an option for generating bills and receipts.
Feedback and ratings
Usually, this is a window where patients can rate their experiences and write reviews for specific providers using a simple scoring system. For usability, this feature must remain unobtrusive within the app interface.

FAQ and educational materials sections
The app should include a FAQ section covering usage and privacy. It should also have an educational section with information about specialists, a map of the institution, and service costs.
Monetization strategies for doctor appointment apps
The ideal monetization strategy for a doctor appointment system depends on the target audience and the organization's business model. Let's look at the most popular types of monetization in this niche:
- Subscription-based.
According to this model, after paying for a monthly or annual subscription, patients get access to advanced features, such as priority appointments or online consultations. - Pay-per-booking.
This model involves charging a fixed fee or a percentage of the service's cost (usually 5-10%) for each appointment. - Advertising.
Based on this model, you can publish advertisements for medical services, pharmacies, insurance companies, and other partner organizations. This can be contextual advertising, static banners, or affiliate programs (for example, you can recommend pharmacies for buying drugs). - Payments for telemedicine services.
This approach to monetization involves charging a fee (either a percentage of the service cost or a fixed amount) for online consultations implemented within the application. - Patient data monetization.
This type of monetization involves selling anonymized patient data to global healthcare corporations. They can be used in the future for both clinical research and to improve the quality of services of partner organizations (for example, insurance companies, laboratories, etc.). - White-label solution.
Finally, you can develop a customizable solution and sell it to other companies under their brand. In this case, you must provide a settings panel where each organization can set individual configurations.
Benefits of doctor appointment booking app development
To understand the benefits of the doctor appointment booking system, we first need to figure out the main pain points such software can solve. Previously, we’ve mentioned some, but for the sake of completeness, let's consider each of them:
- Simplification of the procedure for making an appointment with a doctor.
Earlier, patients had to call the clinic, wait for the admin to answer, and adjust to the schedule. With the app, they can choose the best time and date within a few moments on their smartphone. - Drop in missed sessions and treatment gaps.
With appointment alerts or medication reminders, patients won’t forget about upcoming visits to the doctor and taking medications, which ultimately saves the clinic's resources.
- Transparency of pricing.
Some patients find it difficult to understand the cost of the services; in turn, with the application, they will have access to all the price information before making an appointment. - Comprehensive information about doctors and services.
To prevent patients from choosing doctors blindly, the application can offer them a convenient rating system, reviews, and descriptions of services; thanks to this, they will make a more conscious decision about choosing a particular doctor/service.
- Minimization of paperwork.
Without a doctor appointment application at hand, medical personnel often had to work with paper journals. An app that integrates with the CRM, EHR, and other software will reduce reliance on paper docs. - Higher revenue.
You can sell additional services through the application; moreover, its convenience and transparency increase the likelihood of repeat visits. - Reduced need for human resources.
The application’s launch will help reduce the need for a large administrative staff, allowing existing employees to focus less on routine tasks and more on value-driven activities. - Greater return on marketing efforts.
The patient's behavior analytics can help you craft more targeted offers. With insights into patient habits and preferences, you can create highly targeted offers that resonate with your audience, optimizing both campaign success and budget efficiency while increasing engagement and retention. - Increased competitive advantage.
Modern clinics that offer convenient digital solutions win more patients, improve operational efficiency, reduce no-show rates, and enhance patient satisfaction, all of which contribute to a stronger competitive position in the overall healthcare market.
Steps to build a doctor appointment app
Let’s check the steps included in the medical software development services that our doctor appointment app development company provides.
Market research
At this stage, our doctor appointment app development team defines the application's target audience (the patients' age, smartphone proficiency level, etc.). Next, we analyze the institution's business model for which it’s being created while researching competitors and identifying their strengths and weaknesse

Based on the insights received, we determine the app's basic and advanced features. For example, we want real-time patient monitoring through wearables. We also need to agree on the OS, which can be Android and/or iOS. Lastly, we must choose the best monetization model. Finally, we determine the necessary integrations with third-party solutions and the requirements that must be met (usually GDPR, HIPAA, etc.).
Prototyping and UX/UI design
At this point, our experts create user stories to guide the development of prototypes (first lo-fi, and when agreed upon with all stakeholders, hi-fi). Once the prototypes are finalized, our team starts working on the full-fledged doctor appointment app design. We aim to create user-friendly navigation that cuts off the input needed from the user to complete tasks. At the same time, the team works on the UI, optimizing it for mobile platforms and obtaining WCAG 2.1 accessibility guidelines.
Architecture development
This stage involves choosing an architectural approach (for example, microservices for better scalability, REST or GraphQL for API, and so on). It is also important to plan the processes that will be implemented on the server side (in particular, record management, authorization, etc.). On the client side (usually, this is the patient and administrator interface) and on the database side (as a rule, flows for transactions and caching are separated). We also select specific solutions for implementing the necessary integrations.
Coding
Now, we have everything ready to define the technology stack for the backend and frontend. This decision is based on whether native or cross-platform development will be utilized for the doctor appointment app. Once individual program modules are ready, we proceed with coding and testing each component.
Testing
Since the entire code base is ready, our doctor scheduling app development team ensures that it is fully covered with test cases to perform integration, load, and other types of testing. If there are any bugs, we will fix them immediately and then test the product again. Repeat this process until we meet all the specifications.
Launch and deployment
Finally, our doctor app development experts set up the server infrastructure (optionally, they also introduce CI/CD practices). Ensures data security (through encryption and regular security audits) and carries out a test launch of the software. If there are no critical bugs in the beta version of the application, we release it in the App Store and/or Google Play.
Post-release support and development of updates
This stage includes maintaining app stability, fixing failures, adding new features, optimizing existing ones, updating the design, and scaling with the growing user base.
Doctor appointment app design: Best practices
When it comes to the UI design of a doctor appointment app, we prioritize WCAG 2.1 guidelines. This section details and provides practical examples of their effective implementation for an optimal user experience.

- Readability of information.
Maintain a color contrast ratio between text and background (at least 4.5:1 for normal text and 3:1 for large text). Also, include doctor avatars and icons, ensure text scalability up to 200% (without loss of functionality), and add subtitles and text transcripts for videos (if any). - Ease of navigation.
All UI elements should be keyboard-accessible and have a minimum clickable size of 44x44 pixels. Ensure there’s extra space around buttons or links to prevent accidental clicks and include breadcrumbs for easier navigation. - Clarity of the interface.
Use simple language in the interface, label all form fields, provide input format examples (like "dd.mm.yyyy"), highlight errors, and offer step-by-step instructions for complex tasks, including a progress indicator. - Interface reliability.
Ensure that your application is compatible with assistive technologies (for all functional elements, use ARIA labels). Test your app on various devices and ensure it uses standardized data formats like JSON and XML for smooth communication with integrated third-party servic
Of course, this is only a small part of the best practices you can implement in the doctor consultation app development process. To maximize the loyalty of your audience and better understand what the design should be — read the WCAG 2.1 guidelines directly.
Doctor scheduling app development: Overcoming key challenges
Generally speaking, everyone who is going to develop a doctor appointment app faces challenges to one degree or another. To overcome them effectively, it's crucial to understand them in advance. Let's explore them in detail:
- Integration with software solutions that you already use.
Your application may require integration with systems and services that are either legacy or support non-standard data exchange protocols (i.e., different from HL7 and FHIR). In this case, you may need additional middleware development to ensure seamless data transfer. - Data security.
Medical information must be protected with particular care, as its leakage can lead to large fines and loss of reputation for your organization. To minimize risks, consider data encryption at rest and in transit, implement two-factor authentication and role-based access control. After all, try to regularly conduct pen-tests. - Performance and scalability.
High server load during peak hours can lead to failures in the operation of your application. To prevent this, you can initially choose cloud platforms that support autoscaling for hosting and implement data caching. - Testing complex scenarios.
During testing, your QA specialists risk missing complex interaction scenarios with the application. For example, when several patients simultaneously make an appointment for the same doctor or when the selected order of visits to several doctors is conflicting. To ensure comprehensive coverage of test cases, use automated testing tools. - Accessibility.
A confusing interface can drive users away, leading to fewer interactions with your app. To prevent this, conduct thorough UX research with real users before launch. Based on their feedback, make necessary adjustments to the app's functionality and design. - The unwillingness of personnel to switch to new digital solutions.
Adjusting to new rules might be hard, especially within historically established healthcare practices. You might consider providing training for your staff on how to manage new progressive software.
Beyond technical challenges, there are many business-related obstacles, from USP's definition to the choice of an effective monetization model. This is why, besides carefully selecting the right doctor appointment app development team, consider hiring skilled marketing experts, too.
