Adding an App Store app to OnTopRank Adding an App Store app to OnTopRank

iOS users judge an app in the first minute. If onboarding confuses them or a screen breaks on a smaller iPhone, they delete it and never say why.

OnTopRank is a community of app developers who test each other's apps. Real developers download your app from the App Store on their own iPhones, use it, and share what they found. Every step is verified with screenshots, so you know the testing actually happened.

Why OnTopRank

What you actually get

Real iPhones, real Apple IDs

Testers download from the App Store on their own devices with their own accounts. No simulators, no bots.

Verified step by step

Each download and each piece of feedback comes with screenshot proof, checked by AI and confirmed by you.

Developer-grade feedback

iOS developers notice what matters: onboarding friction, UI polish, layout issues and crashes.

Fair by design

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.

FAQ

Questions developers ask

Who tests my app?

Other app developers on OnTopRank, using their own Apple IDs and their own iPhones. Every tester is a real person who also has an app of their own.

How quickly do testers arrive?

It depends on how many iOS developers are active and how many stars you have. Joining a Testing Pack gives you 10 dedicated testers over five days.

What does it cost?

Nothing to start. You earn stars by testing other developers' apps and spend them to get testers for yours. New accounts get a few stars to begin with.

Do you also support Android?

Yes. One account covers both, and Android apps are tested by developers with Android phones. See Android app testing.
