Tilt gestures feel backward or unresponsive
Hold the phone flat against your forehead with the screen facing the room. Tilt your forehead and phone down for correct; tilt up to pass. The app reads the phone’s true device-relative gravity, so a firm, flat hold works best.
A deck I purchased is still locked
Open the deck library and tap the restore-purchases button in the top-right toolbar. Make sure the device is signed into the same Apple Account used for the purchase.
