Testflight

Testflight (https://developer.apple.com/testflight/) is an awesome tool for distributing the app to beta testers and developers, but it comes with a big drawback--it only works for iOS. It's really simple to set up and use as it is integrated into iTunes Connect, and Apple considers it the official tool for distributing apps within the development team. On top of that, it's absolutely free, and it's usage limits are quite large:

• Up to 25 testers in your team
• Up to 30 devices per tester in your team
• Up to 2,000 external testers outside your team (with grouping capabilities)

In short, Testflight is the platform to choose when you target your apps only to iOS devices.

Since, in this book, we want to focus on cross-platform development, we will introduce other alternatives to distribute our apps to iOS and Android devices from the same platform.
