How to Upgrade to Pro for Cloud Sync
Kwame trains for Scrabble the way he trains for half-marathons — with scheduled sessions and measurable targets. When he gets a second device (a Samsung tablet), he immediately upgrades to Pro so his 1,800+ drill responses are available on both devices. Losing training data between his phone and tablet would feel like losing a training log.
What Pro Includes
- Cloud sync of all drill history, mastery percentages, per-word statistics, and session history
- Cross-device access from any phone, tablet, or browser
- Ad removal
- All Free and Plus features
Steps
-
Go to Settings → Subscription or tap the sync prompt when you add a second device.
-
Review Pro benefits — shows sync, ad removal, and all included features with pricing.
-
Tap "Subscribe to Pro."
-
Create an account (if anonymous) — Pro requires an account. Sign in with Google, Apple, or a magic link. Your existing drill history carries over.
-
Complete the purchase — App Store or Google Play subscription flow. Monthly or annual options available.
-
First sync — after subscribing, your current device's drill history uploads to the cloud. Open Scrabble Trainer on your second device, sign in with the same account, and your history syncs down automatically.
Expected Outcome
- Subscription active
- Drill history, mastery data, and session history syncing across all signed-in devices
- Ads removed
- Any changes on one device sync to the other within seconds when both are connected
Sync Behavior
- Changes sync automatically when you're online
- Changes made offline are stored locally and sync when you reconnect
- Pro syncs all data: per-word mastery, SM-2 intervals, session history, streak data, settings
Restoring on a New Device
Sign in with your Pro account on the new device. Your history syncs automatically. If data doesn't appear, go to Settings → Restore Purchases to re-validate the subscription.
