Beta testing with TestFlight

Internal testing

Up to 100 members of your App Store Connect team can install any uploaded build immediately — no review of any kind. Add them under TestFlight → Internal Testing. This is your day-to-day loop: push a build, the team has it in minutes.

External testing

Up to 10,000 testers outside your team, invited by email or a public link. The first build of each version goes through Beta App Review — a lighter pass than full App Review, usually within a day.

• Create a group under TestFlight → External Testing.
• Attach a build and answer the beta review questions.
• Share the public link or invite emails; testers install via the TestFlight app.
• Builds expire after 90 days — plan re-invites for long betas.

Why bother, if it's optional?

• Beta App Review flags the same crashes, broken flows and metadata problems full review would — while a rejection costs you nothing.
• Crash reports and tester feedback arrive attached to the exact build.
• Real-device coverage: your app on hardware, networks and iOS versions your simulator never sees.

A build that has survived an external TestFlight round with real users goes into App Review with most of its rejection reasons already burned off.
