Android VS iOS Mobile App Testing

Android VS iOS Mobile App Testing

Android VS iOS Mobile App Testing: Whether it’s ordering food, booking a ride, or staying connected with friends and family, we rely heavily on the convenience and functionality of mobile apps. Android and iOS are the most popular mobile operating systems in the world. 

With their increasing popularity, mobile app testing for these two platforms has become an important part of the development process. According to Statcounter, the global market share of Android is 70.9%, followed by iOS with 28.36%.


As many developing nations have lower annual incomes, making it challenging for consumers to purchase expensive smartphones. Therefore, they often choose more budget-friendly Android-based options, such as those offered by Xiaomi, Vivo, OnePlus, and Samsung.

On the other hand, iOS devices are known for their cutting-edge technology and sleek designs, which come at a premium price point that limits their market penetration.

Now that we’ve covered the fundamental similarities between android vs ios mobile app testing in terms of their ecosystem, let’s dive deeper into the various aspects that need to be considered when testing each platform.

Android VS iOS Mobile App Testing: Differences

Device fragmentation 

Mobile device fragmentation refers to the existence of various versions of the same operating system (OS) among different users. This can happen for a variety of reasons, such as users not updating their OS, or manufacturers releasing different versions of the OS for different devices.

In Android, fragmentation arises due to the open-source nature of the operating system. There are many different Android devices on the market, each with its own unique hardware and software configuration. This means that developers need to test their apps on a wide range of devices to ensure that they work properly.

In contrast, iOS has a much smaller device portfolio, which makes it easier to test apps on all supported devices. However, even with a smaller device portfolio, there are still some differences between iOS devices that can impact testing. For example, the iPhone 13 Pro and iPhone 13 Pro Max have different screen sizes and resolutions, so developers need to test their apps on both devices to ensure that they look and perform properly.

System Type

Android uses an open-source Linux OS while iOS is a closed system using Apple’s XNU kernel. This means:

  • Android testing is more straightforward since OEMs can customize the UI.
  • iOS testing is more challenging but takes less time and effort since the system is standardized.

App Store Submission and Approval Process

You can search and download Android apps from Google’s official Play Store. The iOS apps can be downloaded and installed from Apple’s official App Store. Both android vs ios mobile app testing have their own set of app store guidelines that developers need to comply with. The Google Play Store has less strict rules for publishing apps, while the Apple App Store has a more rigorous review process before publishing apps.

Security Features

Android’s open-source nature allows for a higher degree of customization and flexibility, but it also opens up more potential security risks. Therefore, Android app testing often requires a greater focus on security testing.

iOS, with its closed and controlled environment, is generally considered to be more secure. However, this does not mean that iOS app testing can ignore security. Testers still need to thoroughly test for potential security vulnerabilities, especially as iOS apps often handle sensitive user data.

Android VS iOS Mobile App Testing: Key Points

Android TestingiOS Testing
Android apps can be tested on Windows, Linux, or macOS machinesiOS apps can only be tested on macOS machines
Android was initially released on 23 September 2008.IOS was initially released on July 29, 2007
There are many versions of Android in use, and not all devices are updated to the latest version.
This requires testing on multiple versions of the operating system.
Most iOS users update to the latest version of the operating system, so testing can be more focused on the latest versions.
Android is an open-source system, which allows for more flexibility in terms of customization and testing. However, this can also lead to more unpredictability in how the app behaves across different devices and OS versions.iOS is a closed system, which can limit flexibility in testing. However, it also provides more predictability and consistency in how the app behaves across different devices and OS versions.
Emulators: Android emulators are generally considered slower and less accurate than iOS simulators.Simulators: iOS simulators are faster and more accurate than Android emulators, providing a more realistic environment for testing.
App Distribution: For beta testing, Android allows you to distribute your app via any medium. Google Play also has fewer restrictions on app submission, making the testing process potentially quicker.App Distribution: For beta testing, iOS requires you to distribute your app through TestFlight. The App Store also has stricter guidelines for app submission, which can slow down the testing process.
Language Support: Android testing supports both Java and Kotlin.Language Support: iOS testing primarily supports Swift and Objective-C.

iOS and Android Testing Tools:

You can test android app vs ios mobile app testing applications in 3 ways:

  • Emulator
  • Simulators
  • Real Devices (recommended)

Let’s talk about each of these to help you understand as per your use case.

Emulators and Simulators

Emulators and simulators are virtual devices that mimic the software and hardware configurations of physical devices, providing an environment for developers to test their applications without requiring the actual hardware.

Android Emulators:

  • Android Studio Emulator: The Android Studio IDE provides an in-built emulator. It allows developers to emulate various devices and Android API levels.
  • Genymotion:Genymotion is a cross-platform Android emulator that allows you to test your apps on a wide range of virtual devices.
  • BlueStacks: Bluestacks is a  popular Android emulator for Windows and Mac, enabling users to run Android apps on desktop computers.

iOS Simulators:

  • Xcode Simulator: Included in Xcode IDE, this simulator lets developers test their iOS apps on various devices and operating systems without leaving the development environment.
  • iPadian: A third-party iOS simulator for Windows, allowing users to run iOS apps on their PCs.

However, to catch hardware-specific issues and have a real user experience, testing on real devices is important. It’s also crucial for performance testing, as emulators may not accurately reflect the performance of actual devices due to different hardware configurations. This is its always recommended to on real devices.

Real Devices – 

It’s really important to test your mobile apps on actual phones and tablets, not just on computer simulations. Real devices Testing on Cloud can show you how your app affects battery life, how much memory it uses, and how well it works with the device’s processors.

You can either build a device lab of real devices on your own which can cost a fortune or you could lean on smarter solutions like TestGrid infrastructure platform, which gives you access to real devices on cloud, on premise, based on your project testing requirements.
