To take advantage of TestFlight, simply upload a beta build of your app, and use iTunes Connect to add the names and email addresses of people you’d like to test your app. Testers will install the TestFlight app for iOS, watchOS, and tvOS so they can use your beta apps and quickly provide feedback.
Each app can be tested by up to 25 members of your team who have been assigned the Admin, App Manager, Developer, or Marketer role in iTunes Connect. Each member can test on up to 30 devices. Internal testers can access all of your beta builds available for testing.
External Testers and Groups
Once you’re ready, you can invite up to 2,000 external testers who do not need to be part of your team to beta test an app that you intend for public release on the App Store. You can organize external testers into custom groups and share different builds with each group, depending on which features you want them to test. Before external testing can begin, the app must pass Beta App Review to make sure it complies with the full App Store Review Guidelines. Only the first build for the beta version requires a full review.
Up to 100 apps can be tested at a time, internally or externally, and builds remain active for 90 days after they are uploaded. TestFlight supports multiple builds of iOS apps, watchOS apps, tvOS apps, and iMessage apps at the same time.
Each time you invite a tester, they will receive an invitation email and will be prompted to install the free TestFlight app from the App Store on their iPhone, iPad, iPod touch, or Apple TV if they don’t already have it installed. The TestFlight app makes installing beta apps simple, with no need to keep track of UDIDs or provisioning profiles.
