Momentum Support
Purchases
Open Momentum → Settings → Momentum Pro → Restore purchases. Confirm you installed the app from the same Google Play account that made the purchase.
Sync and sign-in
Check your internet connection, restart the app, and retry. Momentum starts with an anonymous account; Google linking is optional and available in Settings.
