What's free and what's in the full version?

Free: every addition and subtraction lesson and both of their drills (every challenge), plus the first lesson of every other track. The full version is a one-time purchase, with no subscription and no ads. It opens the rest of the place value, hundreds, multiplication, division, missing numbers, times tables, leftovers, two steps and fractions lessons, and the multiplication, division and mixed drills.

I bought the full version. How do I get it on another device?

Sign in with the same Apple Account, open Settings in the app and tap Restore purchases. With Family Sharing on, family members get it too.

The purchase says it's waiting for approval.

If Ask to Buy is on, a parent approves the purchase on their device. The full version opens by itself once it's approved.

Why does a times-table question pop up before a link opens?

Links out of the app (this support page and the privacy policy) wait behind a quick grown-up check, so a child doesn't land on the web by accident. Pick the right answer to continue.

How do I start over?

Settings › Reset progress erases progress and scores on that device.
