Five things to check before your beta testers arrive
Your build works on your phone. A tester's first ten minutes are different: the invite has to arrive, their account has to survive a reinstall, and anything that breaks has to reach you with enough detail to fix. Run these five checks with one person who has never seen your app, then invite the full group.

The invite actually lands
Why it matters
The first message many founders get from a beta tester is "I never got the invite." Invitations land in spam, go to an address the tester never checks, or point to a build they can't install yet. On iOS, external testers can only join once Apple has approved your first build for TestFlight, and they need the TestFlight app. On Android, being on your tester list isn't enough: each tester has to open your opt-in link and accept before Google Play offers them the test build. Every tester lost here is feedback you never get.
Test
Invite an email address that has never been used with your app, on a phone that has never had it installed, and time how long it takes to get from the invite to the first screen.
Platform note
If you have a new personal Google Play developer account, Google requires a closed test with at least 12 opted-in testers for 14 continuous days before you can apply for production access. Plan your beta dates around it. Google's requirement (opens Google Play Help in a new tab)
Accounts survive a reinstall and a second device
Why it matters
Testers delete apps to free space, reinstall to "fix" a bug, get a new phone or open the app on a tablet. If their progress, settings or plan is stored only on the device, it's gone, and many will stop testing rather than start again. It's also where sign-in and subscription problems tend to show up first: a tester on a paid plan who signs in on a new device should get the same plan without having to contact you.
Test
Use the app for a few minutes, delete it, reinstall and sign in. Then sign in with the same account on a second device and confirm the same data and plan appear on both.
Unfinished features stay hidden
Why it matters
Most betas ship with features that aren't ready yet, hidden behind a feature flag or a settings switch. The switch often hides the main button but leaves another way in: a deep link, a notification, a settings row, an onboarding step or a search result. A tester who lands on an empty screen reports a bug you already know about, and that report crowds out the ones you actually need.
Test
Switch every unfinished feature off, then go through onboarding, the main task, notifications and settings as a brand-new tester. Nothing should lead to a dead end.
Crash reports name the tester
Why it matters
"It crashed when I opened it" is hard to act on. A crash report becomes useful when you can connect it to a person, a build and what they were doing. Most crash tools, including Firebase Crashlytics and Sentry, let you attach a user ID. Attach an internal tester or account ID and make sure the build number is on every report, so you can match a crash to the tester's message and ask the right follow-up question. Use an internal ID rather than an email address or name, so the crash tool doesn't hold more personal data than it needs.
Test
Trigger a test crash in the exact build your testers will receive, relaunch the app, then confirm you can find the report in your crash tool by tester ID and build number.
Feedback from inside the app
Why it matters
Testers rarely leave an app to write an email, and when they do, the message arrives without the details you need. One visible Feedback option inside the app, which attaches the app version, build number, device and tester ID automatically, turns "the button doesn't work" into something you can reproduce.
Test
Send one piece of feedback from the beta build on each platform and confirm it arrives where you actually read it, with the version and device attached.
Platform note
TestFlight already lets iOS testers send screenshots and comments from the build. Make sure Android testers, and anyone testing a web version, have an equally easy route.
Before you send the invite
- A brand-new address receives the invite and opens the build.
- Reinstalling and signing in on a second device keeps the same data and plan.
- With unfinished features switched off, nothing leads to a dead end.
- A test crash can be found by tester ID and build number.
- In-app feedback arrives with the version and device attached.

Is the build itself not ready for testers yet?
If the beta date is close but the first release still needs to be built or finished, I can scope it with you and build it in your own accounts, with one written scope and one fixed price.
