Tereo helps you memorize Scripture through short daily lessons — you read each verse, hear it, rebuild it, type it from memory, and say it aloud.
If something isn't working, or you have a question this page doesn't answer, email tereosupport@gmail.com and you'll get a reply from the person who built the app.
Open Tereo, go to the Pro screen, and tap Restore purchases. That re-checks your subscription with the App Store. Make sure you're signed in with the same Apple Account you bought it on.
Subscriptions are managed by Apple, not inside Tereo. On your iPhone open Settings, tap your name at the top, then Subscriptions, and choose Tereo. Cancelling there stops the next renewal and you keep Pro until the period you've paid for ends.
No. Tereo works fully signed out, and your progress stays on your device. An account backs that progress up and unlocks friends and leaderboards.
Check your internet connection first, then try again. If it keeps failing, email tereosupport@gmail.com with the exact message you see and roughly when it happened.
In the app: Settings → Account → Delete Account. Full details, including what gets removed, are on the account deletion page.
