OnTopRank is a community of app developers who install, test, and review each other's apps. No bots, no fake ratings, and no risk to your store account - just real developers trying your app and sharing honest feedback.
Fully free · community powered · built for Android and iOS developers
One currency keeps the exchange fair: stars. You earn them by helping other developers, and spend them to get the same help back.
Paste your Google Play or App Store link. Your app joins a feed browsed only by developers who are here to test.
Install an app you like: +10★. Use it, then post an honest store review: +15★. Screenshot proof, checked by AI in seconds.
Your stars pay other developers to install and review your app - real devices, real store accounts, real ranking signals.



Test one app fully = +25★ = a full test of your own app. The loop pays for itself.
An exchange only works if nobody can cheat it. OnTopRank verifies every action three times over, so the installs you receive are as real as the ones you give.
The app, the rating, the text - matched in seconds. Reused or doctored proofs are rejected by hash.
You see the proof for every action on your app and get the final say. Something looks off? Reject it - your stars stay put.
Deadlocked claim? Either side can call in OnTopRank support for a final, binding decision.
Every app comes with a human behind it. Chat directly with the developer testing your app - swap feedback, fix bugs together, and grow each other's apps.
Talk to the person testing your app. What confused them, what crashed, what they'd change - feedback you can ship.
Join 15 developers who pledge to fully test each other's apps in 15 days. One pack = a wave of installs and reviews.
Spend stars to jump to the top of the feed, or pay testers extra with a Featured listing everyone tests first.
See exactly who helped you and return the favor in one tap. Generosity is visible here - and it comes back.
Testers start from smart, app-specific feedback suggestions - so reviews on your app are thoughtful, not "nice app".
In-app, push and email - the moment someone installs or reviews your app, you know, with a link to their profile.
OnTopRank is built around honest, experience-based reviews - testers actually install and use your app before writing anything, ratings are their own choice, and dishonest activity gets rejected and reported. That's fundamentally different from farms selling fake 5-star spam.
You can grow entirely for free. Sign up (+20★), test apps to earn stars, spend them on your own growth. Stars can also be topped up if you'd rather skip the earning - but nobody ever has to pay.
Three layers: AI reads every proof screenshot and rejects reused or doctored ones by hash, you personally approve what happens on your app, and OnTopRank support arbitrates disputes with binding decisions. Cheaters lose their stars and their account.
Both. List a Google Play app, an App Store app, or one of each. Testers on the matching platform will find you.
No. Test as much or as little as you like - the exchange pays you for what you give. Many developers do a burst of testing at launch, spend the stars on their app, and come back when they ship the next one.
Your app is visible to testers the moment you list it. Installs typically start arriving as soon as you have stars to fund them - most developers see their first verified install the same day.
Right now a developer on OnTopRank is picking the next app to test. Give them a reason to pick yours.
