Common questions

I cannot hear the questions. Open Settings, choose Voice, and pick Human, Random or Device. Check the volume slider. Recorded voices play even when the silent switch is on.

Where are my scores and presets stored? Only on your iPhone. Deleting the app removes them.

How do I clear my best runs? Open the Best runs tab and tap Clear best runs at the bottom.

Can I turn off haptics? Yes. Settings, then Feedback.
