Specifically, according to the Exploding Topics resource, in 2024, Android has a 70.93% global market share while iOS only has about 25% of it. However, both platforms are undoubtedly popular, and each of them, with the right approach to development and promotion, can provide product owners with a stable income. Below, we will reveal the differences and similarities between iOS and Android development, paying special attention to security and customization options.
Android vs. iOS App Development: Key Differences
Let's first look at the fundamental differences in Android and iOS development.
Programming languages
When it comes to native development, the most popular Android development language can be considered Java or Kotlin (they are both officially supported by Android’s original IDE, but the last one is preferable for new projects). As for native development for iOS, here, developers will need knowledge of Objective-C or Swift (generally speaking, this is the best option for new projects, while Objective-C is mainly used to support existing solutions that were originally written in this language).
Development environment
As the primary development environment for the Android platform, Android developers use the open-source Android Studio IDE, although in some cases their choice may also fall on Visual Studio, Eclipse, and some other development environments. At the same time, iOS developers usually resort to the help of Xcode with the integrated iOS SDK.
Differences in design
iOS development requires following the platform’s own principles for user interface design listed in the Human Interface Design Guidelines (the main aspects of which are color variety without shadows (Flat Design Depth), minimalism (Clarity), and content-first approach (Deference)). In the case of Android development, these are the recommendations for recreating Material Design (the main aspects of which are expressing the hierarchy of elements through their size, colors, and shadows (Metaphoric Nature), using bold typography to highlight important elements (Bold Graphical Design), visualizing reactions to user actions (Meaningful Animation), as well as adapting the design to devices of different form factors (Adaptive Design)). Also note that Android allows the development of applications for operation in Kiosk Mode – this will be useful for businesses presenting their services and/or products through software installed on corporate Android-based devices.
Hourly rates
According to Glassdoor, the average annual salary of an Android developer in the US ranges from $91K to $135K, while for an iOS developer this range is from $101K to $174K. From this, we can conclude that, on average, the iOS app development cost (if you stick to the hourly rate for specialists) will be somewhat higher compared to the Android app development cost, all other things being equal (in particular, the same number of supported device formats and OS versions).
Complexity of development
It is worth noting that native Android development tools and iOS mobile app development tools are quite easy to deal with and, in general, have a low entry threshold. That is why the complexity of implementing software for a particular platform should be considered primarily from the point of view of ensuring compatibility. The fact is that if you are planning Android development to cover as many user devices with different form factors as possible, your team will have to spend a lot of effort and time. Also, there is the need to provide compatibility with earlier versions of Android and, accordingly, adapt the software for devices that support them. Therefore, the development process for Android can be much longer than in the case of iOS, a platform that is characterized by a relatively small number of compatible user devices. On the other hand, for iOS development, the entire team must be equipped with macOS-based devices — only then will they be able to build the software and successfully test it in an emulator.
iOS vs. Android: Security and Privacy
The main difference between iOS and Android in terms of security lies in the fact that iOS security is more focused on providing strong software protection (which is facilitated by its closed nature and limited number of supported devices), while Android focuses on a combination of software and hardware protection (due to its initial open source nature, which can still be violated by individual vendors creating their own Android-based OSes, as well the variety of supported user devices). In the end, it is impossible to say that one of these operating systems is more secure or, on the contrary, more vulnerable, since by following the standards and generally accepted rules of secure development, you will be able to achieve optimal compliance for your software as well.
Which Platform Has a Bigger Market Share?
At the very beginning of this article, we indicated that Android is the undisputed leader in the mobile software market, with almost 71% market share. However, it is worth noting that the ratio of market shares between platforms may vary depending on the business niche for which the application is created. Moreover, there is rather old research that owners of iOS devices are more willing to download paid applications, while owners of Android devices prefer free software. As a result, this factor can determine your monetization opportunities for your app, too.
Which Platform Has More Customization Options?
In terms of customization options, Android gives developers more flexibility due to the open nature of the platform. Thus, they get more space for creativity, which allows them to implement non-trivial designs and functionality. In turn, the iOS platform is a closed ecosystem with its own strict compliance rules. This concept is aimed at maintaining uniformity of user interfaces, so it will not be possible to create something too non-standard on its basis.
Android vs. iOS App Development: Which One to Choose
Ultimately, we cannot say that development for any one of the platforms, be it iOS or Android, is more profitable. Everything depends on the niche for which the software solution is being implemented, its localization, and many other factors that determine the size of the target audience.
Additionally, it is important to be aware of app store fees for paid software and software with in-app purchases. In particular, iOS paid apps, in-app purchases of digital goods or services, and/or linking out to purchase digital goods and services on your website are subject to a 17% fee (or 10% If you're enrolled in the App Store Small Business Program/the Apple Video Partner Program/News Partner Program or renew a qualifying auto-renewal subscription beyond one year); also, if you use App Store payment processing and related commerce services for in-app purchases, you will be charged a 3% fee. As for Google Play, here, the fee is 15% on the first $1 million in annual revenue (or 30% on annual revenue exceeding $1 million), 15% on products with an auto-renewing subscription (regardless of annual revenue size), and 15% or less for developers who qualify for the Play Media Experience Program.
By the way, if you find that the ratio of potential users for each platform is approximately 1:1, you can consider the cross-platform app development option, which involves creating a single code base for iOS and Android platforms. In this case, you can save about 30% of the budget compared to developing two native applications, and also bring the launch date of your mobile solution closer. The only thing is that, like any other type of software development, this one also has some restrictions.
Regardless of whether you are considering cross-platform or native mobile app development, you can always choose us as a reliable service provider of custom mobile solutions. We will implement your business idea with the minimum possible budget without compromising its quality and select the best approaches and tech stack to ensure its competitiveness and profitability over the long term.
Which programming languages are used for iOS and Android app development?
Android apps are primarily developed using Java or Kotlin, while iOS apps are built with Swift or Objective-C. Swift is the preferred language for new iOS projects, while Kotlin is favored for Android.
What are the main differences in the design approach for iOS and Android apps?
iOS apps follow the Human Interface Design Guidelines, focusing on minimalism and clarity. Android apps use Material Design principles, emphasizing bold typography, meaningful animations, and adaptive design for different devices.
What development environments do iOS and Android developers use?
Android developers typically use Android Studio, while iOS developers work in Xcode. Both environments offer a range of tools to help create and test apps, but Xcode is exclusive to macOS devices.
Is Android or iOS development easier for beginners?
Both platforms offer easy-to-use development tools, but Android development may be more time-consuming due to the variety of devices and versions to support. iOS has fewer device formats, making it somewhat simpler in that regard.
As the practice shows, no idea, even the most brilliant one, when embodied in a digital product or service, will become successful without quality assurance. It, in turn, always includes two non-intersecting procedures that occur before software is launched: the first of them is aimed at obtaining a clear understanding of whether development is moving in the right direction, and the second of them clarifies whether the solution being created meets end user needs. So, how are they called and performed? Let’s find it out right now.
What Is Verification Testing?
In a nutshell, it is a procedure aimed at checking whether the solution being created meets its predefined specifications and generally accepted design and development standards. Software verification testing is performed throughout the entire creation process and involves the use of various automation testing tools and verification methods, such as modular, integrational, and system testing.
What Is Validation Testing?
Unlike the previous type of testing, this one involves planning real-world scenarios that allow the development team to make sure that the solution being created meets its audience’s needs (for this, you can apply, for example, the alpha- and beta-testing validation methods). After that, the solution has to be compared with its specifications. If any discrepancies are found, they need to be eliminated before this solution is released to the public. Actually, that’s why validation testing is repeated until the team achieves full compliance.
Purpose of Verification and Validation
The main goals of verification and validation testing are to fully satisfy the needs of the software solution owner and the audience as well. As soon as these procedures are successfully completed, the project can be launched.
Difference Between Verification vs Validation Testing
So, what about the verification and validation difference? Generally speaking, while verification is aimed at checking the compliance of a product or service with its list of requirements agreed upon between the development team and the owner, validation allows teams to make sure that this service or product will be positively accepted by its end users.
In this regard, the first procedure starts from the very beginning of the development process and lasts until the final testing stage and the second – only after the product/service is completed. This also imposes certain differences on the test data used: during verification in software testing, QA engineers use sample data (in this regard, automation methods are often applied), and during the software validation – real data (usually, manual methods do a great job here).
How Are Verification and Validation Testing Performed?
Now, let's look at the four most popular approaches used for validation and verification in software testing:
Peer reviews, which involve providing a software solution to focus group representatives for a certain period of time in order to obtain feedback on their experience of interacting with it;
Assessments, which are left by focus group representatives after checking the solution for functionality and identifying errors and inconsistencies in it;
Walkthrough, which implies a preliminary explanation to focus group representatives of how exactly to interact with the software solution, after which the latter leave their feedback on how well everything was clear and whether they think some areas need to be optimized;
Desktop-checking, which includes reviewing the software code by specialists (in particular, software engineers).
Tips for Successful Verification and Validation
To ensure these two procedures go smoothly, follow these guidelines:
Define the tasks and goals you are pursuing through these procedures and what the results should be upon their completion;
Choose the specific tools and approaches you are going to use – they should cover all possible scenarios of user interaction with your software solution, as well as generally accepted software development standards;
Create a testing plan, where you will specify deadlines, available resources, and evaluation criteria (along with the acceptable minimum compliance);
Proceed directly to testing in order to identify bugs and inconsistencies that will need to be fixed before the project is released;
Involve representatives of the potential target audience and stakeholders in the testing procedure to get the most objective assessment of the quality of your team's work;
Don't forget to document and monitor the testing results from one bug fixing to another to understand the dynamics of improvements.
Popular Test Automation Tools For Verification and Validation
Although automated testing is considered a standard approach for verification testing only, sometimes, it also brings benefits when implementing validation testing. In this regard, we have compiled a small selection of popular tools that you can use for quality control in software:
Selenium, an open-source web solution that supports a lot of programming languages, such as Java, Python, C#, and so on, as well as integrates with different frameworks;
Appium, an open-source service for automated testing of mobile apps on iOS, Android, and Windows (both native, cross-platform, and hybrid ones);
Robot Framework, an automation framework aiming at implementing acceptance testing and acceptance test-driven development;
Jenkins, an automation server used for continuous integration and continuous delivery that streamlines the build, test, and deployment stages;
TestNG, a popular testing framework that is actively used for testing Java-based software solutions;
Cucumber, an environment for running automated acceptance tests written in Java, Ruby, etc.;
JMeter, a perfect solution for performance testing of web apps.
Conclusion
We hope that we have helped you understand the difference between validation and verification testing, and now, you can also assess their importance in creating high-quality and competitive software solutions. You can also check out our blog to learn more about software development and design.

The results of the model's tests demonstrated that it could predict remission with 100% accuracy. The likelihood of recurrence was correctly identified in 90% of cases.
Researchers at BMJ Health & Care Informatics developed and tested a machine learning model for detecting NASH (non-alcoholic steatohepatitis). This disease is difficult to diagnose. However, the use of ML contributes to more accurate screening of NASH and allows for the timely application of effective treatments.
All of these statistics confirm the vast potential of machine learning in healthcare projects. So, what is this technology most often used for?
Popular Use Cases of AI Projects in Healthcare
According to Morgan Stanley Research, 94% of respondents (medical companies) reported using AI or ML in their practice.
Let’s take a look at which aspects of healthcare these technologies can optimize.
1. Pathology Detection
Machine learning models can be used to analyze various types of images. The goal is to recognize pathological conditions.
For example, they can be used to diagnose cancer, tuberculosis, and other infections.
How does this work in practice? Here are several examples of using ML in the field of pathology detection:
A machine learning-based program analyzes tissue samples and helps identify malignant growths.
ML algorithms recognize tuberculosis by examining sputum samples from an infected person.
ML-based systems help differentiate between benign and malignant tumors.
An example of such software is AIM-PD-L1: an AI and ML-based tool that detects PD-L1. This protein is formed as a result of cancer cell development. Research on this solution showed that its results closely align with human diagnostics. Thus, the tool can be useful in identifying pathology.
Another solution from the same developer, PathAI, is the PathExplore panel for histopathological features. It can analyze tissue images at the pixel level. This allows it to examine millions of cells and accurately identify malignant ones.
2. Medical Imaging and Diagnostics

Here’s how machine learning models can be used in diagnostics based on visual data:
An ML-based system can analyze CT scan results and, with a high degree of accuracy, identify malignant tumors.
Similarly, such platforms can diagnose ischemic strokes, such as hemorrhage, based on brain MRIs.
Specialized ML-based tools allow for retina scans. This helps in the early detection of blindness due to diabetes, specifically diabetic retinopathy.
There are many similar solutions available on the market. Among them are Viz.ai and InnerEye.
The first, Viz.ai, is a care coordination system based on AI. It allows for automate detection of many diseases, including vascular pathologies.
The second, InnerEye, is a solution from Microsoft that significantly speeds up work with patient images. For example, with this platform, doctors can accurately differentiate between healthy and cancerous cells. It also accelerates the start of treatment by 13 times.
3. Personalized Medicine
Each patient is unique due to the following characteristics:
genetic predisposition;
medical history;
lifestyle;
comorbid health issues, and more.
Machine learning-based platforms are able to take all these factors into account when selecting treatment methods.
Here’s how this can work in practice:
ML models analyze genomic data and recommend individualized treatment methods for oncological diseases.
Thanks to predictive analytics, AI-based tools can adjust insulin dosage. This is possible through constant monitoring of its level in the patient.
Machine learning algorithms help choose the optimal antidepressant based on the patient's psychological state and genetic predispositions.
As an example, let's look at IBM Watson for Oncology. This is a machine learning-based system that considers many factors when recommending cancer treatments. These include the compatibility of prescribed medications, possible side effects, and the effectiveness of treatment in each specific case. As a result, the system provides healthcare professionals with several therapy options from which they can choose the most optimal.
4. Drug Discovery Process
The use of ML can accelerate the invention of new pharmaceuticals. Specialized systems show excellent results in discovering the medicinal properties of various substances. They can also analyze the interactions of drug components and optimize clinical trials.
AI in healthcare projects can be used for this purpose as follows:
ML models accelerate the search for antibiotics and antiviral drugs.
AI-based modeling helps reduce the number of failed clinical trials, thus saving time and resources.
Machine learning algorithms can analyze the structure of substances, assisting in the development of new drugs.
A notable example of using AI and ML in creating new drugs is AlphaFold by DeepMind. This tool is designed to determine the structure of proteins, which are the foundation of biological processes in every living organism. Currently, the platform is successfully used for:
fighting malaria;
searching for a treatment for Parkinson's disease;
counteracting bacteria resistant to existing drugs.
5. Epidemic Prediction

Here are some examples of using ML-powered solutions:
Such systems can predict global pandemics. To do this, they analyze data on population movement and disease statistics.
ML algorithms track seasonal disease spikes, such as the flu.
“Smart” platforms can predict outbreaks of specific diseases in high-risk areas. For example, they can forecast cases of malaria or dengue fever.
EPIWATCH is one of the leading examples of such platforms. This tool uses artificial intelligence to predict epidemics that could reach a global scale. The system collects and processes extensive infectious disease data in real time. It has proven effective in providing early warnings about potential pandemics.
6. Remote Patient Monitoring
In recent years, IoT (Internet of Things) devices have become widely used in medicine. These are objects equipped with sensors that can collect and transmit data wirelessly without human intervention.
According to Yahoo!Finance, the IoT market in healthcare, was valued at $58.8 billion in 2024, and by 2032, it is expected to exceed $305.5 billion.
This situation is explained by the fact that AI and ML enhance the efficiency of wearable devices and health monitoring systems in general.
The use of ML in remote monitoring includes the following cases:
Smartwatches can track irregular heart rhythms and detect instances of sleep apnea.
ML models can analyze ECG data in real time. Based on the obtained data, they can predict a heart attack.
AI-based inhalers can track the patient’s readings and warn about an asthma attack.
There are many such solutions on the market. These include popular devices like the Apple Watch and Fitbit. These smart bracelets can monitor heart rhythms and detect uncontrolled breathing stops.
There are also more complex systems available to healthcare professionals. For example, SafeBeing from Somatix. Thanks to wearable devices, this platform responds to patient gestures and draws conclusions about their health condition.
7. Virtual Assistants
Not everyone can visit a medical facility in a timely manner. Moreover, many people need assistance and support after being discharged from the hospital. AI handles these challenges effectively. Developers are actively creating digital assistants with integrated ML algorithms. These assistants are capable of providing first-aid and consulting patients after treatment.
What can such tools do?
These platforms help assess health status independently and suggest possible diseases.
Smart chatbots help schedule doctor visits, remind patients to take medications, and more.

These digital solutions can analyze human speech and identify early signs of Alzheimer’s disease.
Woebot is a smart chatbot that helps people with mental health disorders. It can assess a user’s mood and emotions. Among its functions are conducting conversations with patients and providing personalized strategies for coping with difficulties.
9. Robotic Surgery
Just imagine. Surgeons no longer need to be in the operating room. All procedures are performed by a robot. Sounds like a scene from a sci-fi movie? Nevertheless, this is our reality. Developers have already created robotic systems based on AI that enhance the accuracy of surgical interventions and reduce rehabilitation time.
What can such software do?
Smart surgical systems can perform minimally invasive surgeries.
AI-based software shows excellent results in neurosurgery and orthopedics.
ML models predict potential surgical risks and possible complications.
Here, we cannot fail to mention the famous Da Vinci surgical robot created by Intuitive Surgical. This robotic system offers medical professionals incredible possibilities in the field of minimally invasive surgery. Its features include fluorescence visualization, integrated table movement, a vision cart, and more. This allows for precise and effective surgical interventions.
10. Automation of Administrative Tasks
Routine tasks such as organizing document flow or billing require a lot of time, diverting medical staff from their primary duties — treating patients. The implementation of machine learning-based software allows automation of these processes, reducing the time spent by medical personnel.
AI-powered systems are handling numerous administrative tasks:
Platforms based on NLP can extract data from medical records and update patient electronic charts.
ML algorithms analyze insurance cases, minimizing fraudulent claims.
Smart scheduling systems efficiently manage hospital resources.
An example of such software is the Optum system. It offers numerous solutions for the healthcare business, including a platform for Revenue Cycle Management. Its capabilities include billing, increasing revenue efficiency, medical coding, and documentation.
Benefits of Machine Learning for Healthcare Analytics Projects
The use of ML models in healthcare allows for the analysis of large amounts of medical data. Furthermore, such models are continuously trained and improved. The implementation of tools based on these models brings a number of benefits to both medical professionals and patients:
Early Disease Diagnosis
Identifying serious diseases at early stages reduces mortality, improves the quality of life for patients, and increases the likelihood of full recovery or sustained remission. For medical institutions, this helps reduce their expenses and saves time.
ML models excel at early diagnosis. They analyze medical images, test results, and patient medical histories. They then track patterns and detect even the slightest deviations from the norm.
Improvement in Patient Care Quality
This is facilitated by AI-based digital solutions for personalized care, virtual assistants, and chatbots. They help maintain a person's health outside of the hospital, for instance, after discharge or before visiting a specialist.
At the same time, such platforms help reduce the workload on medical institutions. They can provide the patient with an initial consultation and allow medical professionals to remotely monitor the patient's condition.
Development of the Pharmaceutical Industry
Innovative technologies allow for faster development of new medications. This is a step toward effectively combating various diseases. This is particularly relevant during global epidemics.
Cost Reduction
ML automates many processes in healthcare, from documentation management in clinics to diagnostics and treatment prescriptions. Additionally, the use of smart technologies helps reduce human errors and allows for some patients to switch to home care. As a result, medical institutions can increase the number of patients served and their profits.
Improvement in Treatment Effectiveness
In medicine, predictive models are used, which are trained on large sets of historical patient data. Such models can predict:
the likelihood of recurrence;
the need for hospitalization;
the tendency for the disease to progress.
Medical professionals can use all this data to adjust the prescribed treatment to improve its effectiveness.
Key Challenges in Healthcare Machine Learning Projects
The implementation of machine learning in healthcare projects opens up many opportunities for the industry. We have already seen this today. However, alongside numerous advantages, some challenges may arise for innovators.
Security of Confidential Data
The digitalization of healthcare has led to a particularly sharp issue. We mean the preservation of medical confidentiality and the privacy of patient data. The use of virtual tools implies entering personal information into the system, which increases the risk of data leakage.
To mitigate these risks, maximum anonymity should be maintained. For example, financial and insurance data, as well as the patient's address, should not be included. It is also important to implement reliable data encryption methods and threat notification mechanisms on the platforms.
Quality of Data for Model Training
The effectiveness of ML models depends on the data input into the system. Inaccurate input data can lead to incorrect diagnoses, wrong treatments, and even death.
To prevent this problem, machine learning software should be used under the supervision of highly qualified medical staff.
Skepticism of Healthcare Professionals and Patients
Since machine learning projects in the medical field are still in the early stages of gaining ground, many doctors and patients are not fully confident in its capabilities. The main concerns include inaccurate diagnostics and the complete replacement of human involvement in medical practice.
To build trust, continuous training for healthcare professionals and patients is necessary. It is also important to notify people about the chosen treatment methods.
As for the complete replacement of human labor, this is highly questionable. Scientists believe that innovative technology will, in fact, expand the role of healthcare professionals. Their duties will include overseeing the operation of ML models and interpreting their results.
Difficulty of Integration with Existing Software
To ensure the smooth operation of medical institutions, new software products need to be seamlessly integrated into the existing infrastructure. The task becomes more complex because clinics may be using outdated systems that are not compatible with new technologies.
To solve this problem, investment in qualified IT personnel and gradual replacement of old software with new ones is necessary.
Technologies Used in Machine Learning Projects in Healthcare
Such high efficiency in AI projects in healthcare is achieved thanks to the wide range of technologies used in specialized software. Let's look at the main ones.

better awareness of these technologies among doctors and patients;
an increase in the number of developers capable of creating and integrating innovative systems;
a growing demand for skilled healthcare services and medications.
What can we expect in the near future?
Transformation of Primary Healthcare
AI and machine learning systems will take on more responsibility during a patient's initial visit to the doctor. They will classify patients based on their risk level, using examination results. Patients with a low probability of illness will be notified immediately. Those with a high risk will be referred to specialists.
This will reduce the waiting time for referrals and ease the burden on specialists.
Improvement of Healthcare Accessibility
According to the International Labour Organization, 56% of people living in rural areas have no access to healthcare. In cities, the situation is better but still concerning, with 22% of the population unable to access medical services.
