Mobile App Testing Services
We test on the same mobile devices as your users!Start a Project
Mobile app testing services will ensure that native, mobile-web, or hybrid apps meet any requirements. These services contain a huge number of checks on multiple devices, screen resolutions, operating systems, internet connections, and more.
Usually, getting an app live on Google Play takes a few hours. For the App Store, it’s a few weeks. We can’t really say how long the errors will influence current and new users while the apps are in the review process.
Testing mobile applications has saved more than one app from terrible reviews and audience loss.
The key to making your brilliant idea successful is to use a high-quality mobile testing service. That is why you need the help of an experienced mobile testing company, one that knows all the specifics and bottlenecks of the process.

The stable and structural testing process
Highly experienced mobile testing engineers who knows the specifics
Avoiding violent backlash caused by defects
Improving the usability of your app
Mobile application testing
From the analysis of requirements through test planning and execution — to reporting issues and maintaining solutions
During functional testing of mobile application, we ensure that the application meets the requirements using a deep understanding of its logic to vastly improve product quality
It is important to ensure that the application is as comfortable as possible for the end user
Device fragmentation testing is performed on various platforms, form factors, screen resolutions, sizes, etc
Mobile application performance testing define an optimal response time from the server; detect memory usage and bandwidth issues
Ensure that incoming calls, low signals, battery charging or dead, rotation, Bluetooth on/off, voice commands, etc. can’t affect the application working as well
The app should also be stable and shouldn’t depend on connection speed or state (Edge, 3G, LTE, Wi-Fi, poor signal, bad connection, network interruption, etc.)
In the process of localization testing, special attention is paid to the languages supported by the application, accuracy of translation of various interface elements and correctness of date/time settings, etc
Testing is not limited to searching for errors. We also provide recommendations for UX and UI improvements and more. We clearly understand what will be convenient and powerful for an end-user — and what has to be improved
During Mobile App Testing We Check
Testing on various devices and operating systems
The display of elements in portrait and landscape modes
App functionality in low battery and charging mode
Different types of internet connections (Wi-Fi, 3G, 4G, offline mode)
Low signal strength
App testing on mobile and tablets (as well as testing UI on different screen resolutions)
Device specific actions (multi-touch or single touch, device rotation, shake, long press or tap, etc.)
Ability to move the application to the memory card and vice versa
Compatibility of OS versions with the old/new SDK versions
Check app behavior with incoming calls/SMS
3rd party integration
Locations and languages
Permissions to access microphone and camera
Bluetooth on and off

What tools/services would be useful when performing mobile application testing?
Because of the variety of devices, cross-platform testing is essential. Even if you do not have enough real mobile devices, you can use cloud services for cross-platform testing, such as BrowserStack, SauceLab, AWS Device Farm.
Android Studio and Xcode are the best choices when it comes to emulators and recording device logs.
Why is it important to test Mobile Application updates?
Developers can forget about migrating data from older versions to the updated one, causing critical errors, deletion of user purchase data, or affecting the parts of the application that worked by fixing other bugs. Without proper testing, you risk making your users think about whether they should use the app, or leave poor reviews.
Should I use real devices or emulators?
Using physical devices lets you get a feeling for the app, how it performs on real hardware, and all the factors that may contribute to it working or crashing. App emulators don't allow for a true user experience. Using a full-sized keyboard with mouse is a completely different experience than physically navigating the mobile application via touch and gestures.
The biggest reasons why testing on real devices usually leads to better results:
User experience and usability
You cannot emulate how the app is used in real life. How does it look when you are under the sun? Does the interface fit with swipes?
Emulators can’t show how an app reacts during phone calls, receiving messages, etc.
Memory Related Issues
Real devices multitask unlike emulators, so a lot of processes and applications are performing simultaneously. They don't represent the real state of the app performance.
Display related issues
Separate from resolution, there are issues with the quality of display in general. There might be mismatching between the designed UI and how it looks on a real device.
Battery related issues
Emulators can’t test the power efficiency of your app. What if it kills your device in a couple of hours?
Customization and Platforms
You need to ensure that your app isn't influenced by any other pieces of software on the device
Which checks should be performed for the security of mobile applications?
Security testing is necessary to guarantee the security of information and customers. The following checks must be performed:
Ensure the requirement of a strong password
The security system must not allow access to other users credentials
You must be sure that financial information is reliably protected
Ensure that access to private user content cannot be obtained to bypass authentication
Make sure that SQL/CSS injections can't harm the application, destroy the user data, or make it public
Check that issue with buffer overflow can't lead to a loss of the user information
How is the testing of a mobile application organized?
Mobile application testing is different from testing desktop or web apps. Before starting, you should determine the type of mobile app (mobile-web, native or hybrid) which helps you to choose a strategy. Also, you should choose the devices type (real, emulators or simulators, as well as cloud testing services). Each of the types has its advantages and disadvantages, but competent specialists will always help you in choosing the right one. Then you should understand when to choose manual and when to use automated testing.
Testing mobile apps starts with the documentation phase, which is the foundation for future work. Some of testing types usually included on initial stages are functional and UI/UX. As soon as the QA engineer is convinced that the GUI completely coincides with the layouts on different devices, with different screen diagonals, an important stage begins - testing for compatibility. When the application is perfectly compatible, we can safely move on to testing the performance and security.
The latest stage is Certificate Testing. There are certain rules for organizing an installation file (.apk) and rules for applications design for each application store. Certification testing verifies that the app meets the requirements of the most popular stores like Google Play and App Store.
What trends should be tracked to improve the testing process?
These are strict rules from Apple and Google describing the process of publishing in app stores. It will be useful practice to track them despite in general, but they are quite trivial.
Also, Google and Apple provide design guidelines. Following them is necessary. Keep track of the direction each platform is moving. This will give you a better understanding of users’ expectations and the opportunity to increase the quality of UI and UX testing.
