What is TestFlight used for?

TestFlight is used for beta testing iOS, tvOS, watchOS, and macOS applications among a limited number of users before their public release in the App Store.

Main features:

• Distribution of beta builds: Easily share test versions of the app with internal (App Store Connect team members) and external testers.
• Feedback collection: Testers can send feedback directly to developers, including annotated screenshots.
• Usage analytics: Provides crash data, usage time, and other metrics to assess stability and performance.
• Tester management: Invite, remove, and manage tester groups.
• Support for multiple versions: Test several builds of the same version or different builds simultaneously.

This is an important tool for obtaining real feedback and identifying issues before the official release, helping to improve app quality.
