Originally developed by Burstly, which Apple acquired a couple of years ago, TestFlight enables over-the-air installation and testing of iOS, watchOS, and tvOS apps in their prerelease versions. Essentially, it allows developers to invite internal and external beta testers to try out and provide feedback about their apps in progress.
Along with the usual round of stability and performance improvements, the latest update to TestFlight adds support for iOS 9.3 for iPhone, iPod touch, and iPad, and watchOS 2.2 for Apple Watch.
Both software versions are yet to be officially released by Apple: iOS 9.3 is already available both to registered developers and public beta testers, while watchOS 2.2 is open only to developers for now. The former features multi-user support for education users, new 3D Touch shortcuts for some stock apps, and a new Night Shift screen brightness adjustment mode, while the latter includes the ability to pair more than one Apple Watch with iPhone and a revamped look for the Apple Maps glance.
The official release of these software updates are expected to happen or at least be announced during Apple’s rumored media event on March 15, which is said to feature the launch of the so-called “iPhone 5se,” the “iPad Air 3,” and new Apple Watch bands.
In any case, developers can now rest assured that any apps that they’ve designed to work with iOS 9.3 and watchOS 2.2 can be properly distributed, installed, and tested with TestFlight.
Compatible with iPhone, iPod touch, and iPad running iOS 8.0 or later, TestFlight is available on the App Store for free.
