How does a game work?

Seven rounds of one minute each: addition, subtraction, multiplication, division, percentages, powers, then a mixed round. Three right in a row moves you up a level; a miss moves you down one.

What's the difference between a game and practice?

A game is all seven rounds and counts towards your streak and best. Practice is a single one-minute round of one question type, aimed at the facts you find hardest. It doesn't count, so you can practise freely.

How do I turn reminders on or off?

In the app, go to Settings and tap Daily reminder. You can also change notifications in iOS Settings at any time.

How is "better than X% of players" worked out?

For now it's an estimate from a simulated population of players, which is why it says "est.". It will switch to real player data once there's enough of it.

How do I export or delete my data?

Settings → Your data. Export my data saves everything as CSV files; Delete all data erases it permanently. Deleting the app also removes it.

Which languages are supported?

English, Japanese, German, Simplified and Traditional Chinese, Korean, French, Spanish, Brazilian Portuguese and Italian. Change it in Settings → Language.
