What we build

Mobile App Testing: what we build

Device-matrix, automated and pre-release testing for mobile apps. Here are the six kinds of mobile app testing services work we are asked for most often.

Test coverage

What we vary when we test a mobile app

Most mobile bugs appear only under specific conditions. These are the six dimensions we deliberately vary.

Dimension What we vary Why it matters
Devices and screens Small phones to tablets and foldables Layouts break on sizes nobody checked
OS versions Current and older iOS and Android versions Features behave differently across versions
Network Wi-Fi, mobile data, weak signal, offline Apps must fail gracefully and recover
Interruptions Calls, notifications, backgrounding, low battery State is often lost when the app is interrupted
Permissions Location, camera and notifications allowed or denied Denied permissions often cause crashes
Accessibility settings Large text, screen readers, reduced motion Many users rely on them every day

Straight answers

Is Mobile App Testing right for you?

We would rather recommend less than sell you more. Here is how we judge it.

A good fit when

  • Your app crashes on some devices
  • Releases break existing features
  • You are preparing a major launch
  • You have no automated mobile tests

  • You need testing across web and mobile together

    See Mobile & Digital Testing in our QA services.

  • The app is still being designed

    Usability testing of prototypes comes first.

  • Crashes come from the backend

    Backend and API testing may be the real need.

FAQ

Mobile App Testing FAQ

Why test mobile apps on real devices?

Real devices reveal problems that emulators miss, such as performance on older phones, manufacturer-specific behaviour, battery use, sensors and real network conditions. We use real devices plus cloud labs for wider coverage.

How many devices should we test on?

Enough to cover most of your users. We use your analytics to choose the devices and OS versions that matter, then add a few edge cases such as small screens and older versions.

Can mobile app testing be automated?

Yes. We automate critical flows such as sign-in, search and checkout with tools like Appium, XCUITest and Espresso, and run them on every build. Exploratory and usability testing stay manual.

Can you test an app you did not build?

Yes. We start with a test plan based on your app, users and release process, then work alongside your developers.

Do you test apps before App Store and Google Play submission?

Yes. We check store guidelines, privacy declarations, crash-free stability and key flows, and run TestFlight and Google Play testing tracks before release.

What is the difference between mobile app testing and QA services?

Mobile app testing focuses on iOS and Android apps and their devices. Our wider QA services cover quality strategy and testing across web, mobile and APIs.
