Frequently Asked Questions

The ranking submission failed / times out

This usually means the network connection was interrupted. The rest of the app works fully offline, so you can keep practicing and try submitting your score again later.

How do I remove ads?

You can remove ads permanently with a one-time in-app purchase from the app's menu.

How do I restore my ad-removal purchase after switching devices?

Use the restore-purchases option in the app's menu after signing in to the same App Store / Google Play account you originally purchased with.
