Frequently Asked Questions

How do I change the difficulty?
Open the settings from the board screen and pick your difficulty tier. Every tier is available from day one — no unlocking required.
Is my progress synced across devices?
No. All of your grids, times, and settings are stored locally on your device. Nothing is uploaded to a server or synced between devices.
I lost my progress. What happened?
Because your data lives only on your device, reinstalling the app or clearing its storage will remove your saved grids and statistics.
How do I unlock unlimited grids?
Tap the upgrade option in the app to purchase the Annual Pass — a single transaction of roughly $1 USD (or the local equivalent) for a full year of unlimited grids. No monthly subscriptions.
I bought the Annual Pass on another device. How do I restore it?
Use the "Restore Purchases" option in the app while signed into the same App Store or Google Play account you bought the pass with.

Troubleshooting

The app crashes
Make sure you're running the latest version of Gridfulness from your app store. If it keeps happening, email us with your device model and OS version.
The number bar or timer disappeared
That's the minimalist mode. Head into settings to turn the timer and number input bar back on.
