TestFlight beta
How to test DecisionEngine.
Two flows — that’s all you need to know.
Install the app
TestFlight is Apple’s second App Store — just for test apps. Set it up once and everything else happens by itself.
-
Get TestFlight
Free on the App Store — right here.
-
Tap the invitation link
TestFlight opens → “Accept”.
-
Tap “Install”
DecisionEngine appears on your home screen like any other app. Requires iOS 26.
-
Turn on automatic updates
Enable it for DecisionEngine in TestFlight — new versions arrive by themselves.
Beta builds expire after 90 days — there will be a newer one long before that. And as always: everything is computed locally on your iPhone.
Something’s off? Here’s how to report it.
Straight from the problem screen, in 30 seconds. Screenshot, device and iOS version travel along automatically.
-
Stay on the screen
Don’t tap anything away — that exact picture is what we need to see.
-
Take a screenshot
Press side button + volume up together.
-
Tap the preview bottom-left
The little thumbnail that appears after the screenshot.
-
Tap the share icon at the top
Then pick “Share Beta Feedback” from the list — the row only appears for TestFlight apps. This is what it looks like (real capture):
-
Three sentences, send — done
- What were you trying to do?
- What did you expect?
- What happened instead?
No screenshot handy? Open TestFlight → DecisionEngine → “Send Beta Feedback” — same channel.
After a crash, iOS asks whether to share the report — please tap “Share”. And: feel free to paint over any health values on the screenshot before sending.
Every report is read. What testers report helps decide what gets built next.
