Apps waiting for testers in OnTopRank
Most indie Android apps launch to silence. Nobody has opened them except the developer, so the first real users are the ones who find the crash on step two of onboarding.
OnTopRank is a community of app developers who test each other's apps. You test theirs, they test yours. Every tester is a real person on their own device, every step is verified with screenshots, and the feedback comes from people who know how apps are built.
Testers are developers installing from Google Play on their own phones. No emulators, no bot farms, no shared accounts.
Each install and each piece of feedback comes with screenshot proof, checked by AI and confirmed by you.
Testers spot onboarding friction, confusing screens and crashes, and tell you about them in plain words.
You earn stars by testing other apps and spend them on testers for yours. Testing Packs match 11 developers for a focused five-day round.
