OVERVIEW

Mobile App QA and Testing built around how your business works.

Our goal

Ship stable, high-quality mobile releases that protect ratings, retention, and revenue.

Mobile apps fail in ways web apps don't: fragmented devices, OS updates, flaky networks, background interruptions, and store review rules. At Creuto, we build mobile QA programmes that catch these issues before your users do.

A crash on launch or a broken checkout on one popular device can undo months of product work and drag down store ratings overnight.

We start by mapping your users' real device, OS, and network mix, then build a test strategy around the journeys that matter most to your business.

Manual exploratory testing covers usability and edge cases, while automated suites built with Appium, Espresso, and XCUITest guard against regressions on every build.

Testing plugs into your CI/CD pipeline, so each pull request and release candidate is validated before it reaches TestFlight, Google Play testing tracks, or production.

Whether you need a one-off pre-launch audit or an embedded QA team for every sprint, we scale testing to your release cadence.

What every engagement includes

  • Real-device testing on iOS and Android
  • Automated regression with Appium, Espresso & XCUITest
  • Performance, battery & network testing
  • Security and accessibility checks
  • CI/CD-integrated release validation
