You can install the beta app on up to 30 devices. Then, accept your email invitation or follow the public link invitation to install the beta app. To get started, install TestFlight on the device you’ll use for testing. Note: To automatically download additional in-app content and assets in the background once a beta app is installed in iOS 16, iPadOS 16, or macOS 13, turn on Additional In-App Content in your App Store settings for iPhone, iPad, and Mac. In-app purchases are free only during beta testing, and any in-app purchases made during testing will not carry over to App Store versions. To install the App Store version of the app, download or purchase the app from the App Store. When the testing period is over, you'll no longer be able to open the beta build. Alternatively, with TestFlight 3 or later, you can turn on automatic updates to have the latest beta builds install automatically. TestFlight will notify you each time a new build is available and will include instructions on what you need to test. You can see how many days you have left for testing under the app name in TestFlight.
If you’re a member of the developer’s team, the developer can give you access to all builds or certain builds. You’ll be able to access the builds that the developer makes available to you. To test beta versions of apps and App Clips using TestFlight, you’ll need to accept an email or public link invitation from the developer and have a device that you can use to test.
