iOS app testing on real iPhones
The simulator misses real-world problems. Other developers run your published app on their own iPhones and report what breaks, with model and iOS version.
Findings with model and iOS version
Every task asks testers to name the iPhone model and iOS version, so you can reproduce a bug instead of guessing.
Check updates before review
Walk a small group of developers through a new TestFlight build before you submit it to App Review.
A fair exchange
You earn a credit for every feedback you write and spend it on feedback for your own app. No store reviews are traded.
