Mobile app testing on the phones your users actually own
Crashes often live on devices the team does not have. We build the device matrix from real usage and test on real hardware and real networks.
The whole story, short
The problem
Crashes appear on budget and older phones nobody on the team owns.
What we did
- Set a device matrix strategy
- Test on real devices
- Automate with Appium
- Review crash analytics
- Test network conditions
The outcome
Real devices chosen from your usage data
What goes wrong
- Crashes appear on budget and older phones nobody on the team owns.
- Memory issues surface only on low-RAM devices.
- Payments fail or duplicate when the connection drops.
- Store ratings fall before the team can reproduce the issue.
Why the usual fix falls short
Emulators miss hardware, manufacturer and memory issues. Testing on the team’s own phones covers only a small slice of real users.
How we tested it
Set a device matrix strategy
Use analytics to choose the device and OS combinations real users have, including budget models.
Test on real devices
Run on a real-device cloud to reproduce hardware and manufacturer-specific problems.
Automate with Appium
Automate the main flows and connect them to CI, so each release candidate is tested.
Review crash analytics
Rank crash reports by affected users and business impact.
Test network conditions
Test payments and cart recovery on slow, unstable and interrupted connections.
Questions buyers ask
How many devices should a mobile app be tested on?
There is no fixed number. Use your analytics to find the devices, OS versions, and screen sizes your users actually have, then cover the combinations representing most of them. Add older or low-end devices where they matter, and revisit the list regularly because usage changes.
Are real devices better than emulators?
Each has a role. Emulators and simulators are fast and affordable for early development checks. Real devices are needed to find hardware, manufacturer, performance, battery, and network issues. Most teams use emulators during development, then confirm important flows on real devices before each release reaches customers.
What is Appium used for?
Appium is an open-source framework for automating native, hybrid, and mobile web apps on iOS and Android. Teams often use it to run one test approach across both platforms. Platform-specific tools such as Espresso and XCUITest can be faster, so the right choice depends on the app and team.
