Mobile App QA & Testing

Manual and automated testing that ships a stable, bug-free app. We work with clients across Uzbekistan.

Ships only when every test passes

Manual and automated testing across real devices before your users see it.

QA isn’t a final glance — it’s every flow, tested on real devices. We check add-to-cart, payment, push, offline mode and deep links on iPhone, Pixel, iPad and Galaxy, so a stable, bug-free app reaches the store.

How it works

1

Test plan

We map every critical flow and edge case, and the real devices and OS versions to cover.
2

Manual testing

Hands-on testing across real iPhone, Pixel, iPad and Galaxy devices — the way users actually tap.
3

Automated e2e

Automated end-to-end tests for core flows, so every build is re-checked without missing a case.
4

Regression & sign-off

A full regression pass before each release — the app ships only when everything is green.
