A tester exchange for indie devs,
built by indie devs.
Register your app while you're still building it — testers queue up in parallel, so by the time you're ready, Google Play's 12-tester, 14-day requirement is already handled instead of a last-minute scramble. Building for iOS or the web? Same head start, quicker turnaround.

How it works
Other exchanges make you find testers one at a time, after you're already blocked. Percol8 flips it — build your queue before you need it, so testing starts the moment you're ready.
Register your app
List your app and what kind of testing it needs — Android, iOS, or web.
Testers queue up
Real devs join while you finish building. No begging on Reddit, no scrambling once you're blocked.
Test together
When you're ready, everyone jumps in at once. Earn seats testing others, spend them getting your own app tested next.
Built for devs like you
Your app's ready, Google Play isn't
12 testers, checking in for 14 straight days, before you can even apply for production access. You don't have 12 friends with Android phones — Percol8 does. Register early and your waitlist fills while you're still polishing the UI.
Building for iOS or the web
You don't need 12 testers and 14 days — you need a handful of people who'll actually use it and tell you what's broken. List a quick-test slot and get structured feedback back within days.
App still in progress
Start testing other devs' apps now. Every test earns you seats — so when your own app is ready, your waitlist is already primed instead of starting from zero.
Founding offer
Access opens in waves — top of the waitlist first. Founding members get free seats: enough to launch your first app without testing anything first. Invite other devs to percolate up the list.
FAQ
- What's the 12-tester rule?
- Since November 2023, Google Play requires personal developer accounts to run a closed test with 12+ opted-in testers for 14 consecutive days before they can apply for production access.
- Is this free?
- Yes. Devs test each other's apps — no paid testers, ever.
- When do I get access?
- Access opens in fixed-date waves, top of the waitlist first. Referring other devs moves you up faster — but a blocked app always outranks a curious sharer.
- What's a seat?
- Percol8's single currency. Earn seats by testing other devs' apps, spend them to get your own app tested.
