[03] The mobile gap
Crash-free doesn't
mean bug-free
Your unit tests pass. Your crash rate is fine. The bug that costs you a one star ships untested between those two signals. Your customers find it first.
There's no fast rollback in mobile
Once a build is live, fixing it takes another submission and another review. Two days of bad reviews accumulate before the patch lands.
You forgot what onboarding feels like
Your team has been in this app for years. The 5-minute window for new users to figure it out gets shorter every release. Your tests don't measure that.
Every bug has a public record
Sentry hides your regression. The App Store doesn't. Once a customer writes the review, it's part of your acquisition funnel forever.
The exception was caught. The user wasn't.
Your error boundary did its job. The retry button works. The user still left, because the flow that mattered to them was still broken.
[04] Per-regression evidence
Every regression, fully recorded
When a journey breaks, you don't get a crash log and 'works on my device'. You get the recording from the simulator, screenshots at every key moment and the step trace with timing.

[05] How it works
Four steps to automated mobile app testing for iOS and Android
Upload a build, describe critical flows in plain language, and let TesterArmy catch regressions on every release - before App Review or your users see them.

Explore real bug finds, QA tips, and client case studies from our work in practice.
July 22, 2026Introducing Scout: API Testing Built for AI Agents
We built Scout, an open source CLI that gives coding agents a safe harness for testing APIs. Point it at an OpenAPI spec and it sweeps, fuzzes, and records findings - with guardrails on by default. In this walkthrough it finds three real bugs in the Swagger Petstore.
July 17, 2026TesterArmy Now Supports Netlify Deploy Previews
Netlify Deploy Previews can now trigger TesterArmy automatically. Test every pull request on its real preview URL and get the results back in GitHub before merge.
July 16, 2026How Do We Use TesterArmy at TesterArmy?
We ship TesterArmy with TesterArmy. Here is how we dogfood our own QA agent - what we test, how we wire it into PRs, and what it catches.
[07] FAQ
Mobile app testing, answered
AI mobile app testing is automated testing where an AI agent runs your iOS or Android app like a real user - tapping, typing, and verifying flows from a plain-English description instead of hand-written test code. TesterArmy runs these tests on cloud simulators on every build and reports regressions with recordings and screenshots.
Upload your build, describe the flows you care about in plain English - 'sign up, complete onboarding, buy the monthly plan' - and TesterArmy turns each one into an automated test that runs on every release. No Appium, no test framework, no device lab. Anyone on the team can add coverage.
Yes. TesterArmy runs iOS apps on cloud iOS simulators and Android apps on cloud Android emulators. The same natural-language journey definitions apply across both platforms.
Use the tester-army GitHub Action. Provide a build artifact and your TesterArmy credentials. We handle simulator setup, app installation, test execution, and orchestration. Results come back as a PR check with screenshots and recordings.
Yes. We test the compiled binary - the framework you used to build it is transparent to us. Native, React Native, Expo, and Flutter apps all work the same way.
Paywall screens, plan selection, upgrade and downgrade UX, restore purchases, and post-purchase navigation - yes. Native StoreKit purchase sheets require sandbox configuration on the simulator. Contact us if you need help wiring that up.
Yes, for native iOS apps. The agent taps your Apple Pay button, verifies the payment sheet with your line items and total, authorizes it, and follows your post-payment flow through to the confirmation screen. Simulators authorize with a dummy token, so your app runs end to end while no real payment is processed.
Yes. Email and password works out of the box. Google and Apple OAuth run through stored credentials. OTP and magic-link flows use our agent's own inbox - it reads the code or link inline and continues the journey. Face ID and Touch ID aren't supported on iOS simulators in the general case.
Different layer. Detox and Maestro are frameworks - you write and maintain the tests, debug the flake, manage the selectors. TesterArmy is a service - you describe the journey in plain English, we run it on a cloud mobile simulator, maintain it, and ship evidence on every build. No test code in your repo.
Your next mobile bug will be live before you can pull the release
Mobile QA is the gap between green CI and a one star review. TesterArmy fills it. We test the flows that decide your rating, on every build, in minutes. Building with React Native or Expo? See React Native app testing and Expo app testing, or wire tests into your pipeline with the Expo EAS integration. Coming from Maestro? Read the migration guide.
