Beta expiry

1
Download the TestFlight app
Open the App Store on your iPhone or iPad, search for TestFlight by Apple, and install it for free.
2
Get your invite link
Tap the button above — it will open your TestFlight app directly to this beta. If TestFlight isn't installed yet, complete step 1 first, then return here.
3
Open the link on your iPhone or iPad
Tap the invite link on your device. It will open TestFlight and display the beta program details page automatically.
4
Tap "Accept" then "Install"
In TestFlight, tap Accept to join the beta, then tap Install. The experience is identical to installing any regular app — no extra configuration needed.
5
Updates & feedback
When the developer releases a new build, TestFlight will notify you automatically. You can also submit screenshots and feedback directly from within the app.
Things to know
- The beta and the production app share the same Apple ID — uninstalling the beta lets you switch straight to the release version
- TestFlight will notify you before a build expires; the developer will need to send a new invite at that point
- No extra account needed — your existing Apple ID is all you need
- If the link says "expired," just ask the developer to generate a new one

1
Receive the invite email
Tap the button above to open the Firebase tester page. You'll need to sign in with a Google account — make sure to use the Gmail address your developer added.
2
Tap "Get Started" in the email
Open the invite email on your phone and tap the Get Started button. Your browser will open the Firebase App Distribution tester page.
3
Sign in with your Google account
You'll be asked to sign in with the Google account the developer invited. Once authenticated, you'll see the list of available APK builds to download.
4
Allow "Install unknown apps"
Before downloading, you'll need to allow your browser to install apps. Go to Settings → Security → Install unknown apps, then enable it for your browser.
5
Download and install the APK
Back on the Firebase tester page, tap Download. Once the file downloads, tap the notification to install it.
6
Future updates
When a new build is available, you'll get a new email notification. Repeat steps 2–5 to install the update over the existing version.
Things to know
- You must use the exact Gmail address the developer added — a different email won't have access
- After installing, it's good practice to disable "Install unknown apps" again to keep your phone secure
- If the developer distributes through Google Play's Closed Testing channel instead, just click the invite link — Play Store handles the rest, no APK needed
