About this app

Twelve Testers helps Android developers find other developers for mutual closed testing.

Google Play closed testing needs real people on your tester list. Asking friends only gets you so far. Here, you pick an app to test, offer yours in return, and both sides actually do the work.

How it works
1. Create an account and post your app (Play closed-test link, what you need testers to try).
2. Browse other indie apps and request a swap.
3. When both sides accept, you join each other’s tester lists, install, use the app, and leave honest feedback.
4. Track your swaps and sessions in one place.

What this is
A reciprocal testing marketplace for indie Android developers. Private QA feedback between people who are testing each other’s builds.

What this is not
Not a review exchange. Not paid installs. Not a way to farm Play Store ratings. Fake reviews and ranking manipulation are not allowed.

Who it’s for
Developers (18+) running Google Play closed testing who want fair, two-way tester swaps.
