Become a Tester — Help Launch Our Apps
Useful Appz is a tiny studio, and this is our standing tester pool. Join once, and you're first in line for every app we ever test — you get new apps before anyone else, and your testing is what gets them launched.
Here's how it works: join the pool below, and when a new test opens we tap you with that app's link. Prefer tapping in right now? The apps that are open today are listed below — the button takes you to Google Play, where your tap is the one that counts.
10 people are already in the tester pool.
BECOME A TESTER — FIRST IN LINE TO TRY THE NEWEST APPS.
The FillMyList app puts the whole pool in your pocket: new apps appear in FillMyList the moment they open, and you're first in line for every one.
UsefulAppz Folder
Keeps every Useful Appz app on your phone, current — it reports your installed list back so the newest versions always reach you first. Free, ad-supported.
TIRED OF LOOKING FOR TESTERS? Developers: inside the FillMyList app, one payment fills your tester list to FULL — $24.99, one app, testers cycled in waves until 12 confirmed, and kept full through your 14 days. Get FillMyList and start a fill.
Join the tester pool
Joining the pool doesn't sign you up for an app by itself — Google only counts your tap on the app's own Google Play page. The pool just makes sure you hear about every new test first. We only email you about app testing, and you can ask to be removed any time.
Open for testing now
Every app here needs 12 testers opted in before Google Play lets it launch. Tap an app, hit Become a tester, and stay opted in for about two weeks. The whole list takes about two minutes.
