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

Free: every Negative numbers lesson, the Integer blitz game with every challenge, and the first lesson of every other track. The full version is a one-time purchase, with no subscription and no ads. It opens the other 24 lessons and the Solve for x, Ratio tables, Percent of and Powers and roots games.

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.

Where should I start?

The Learn tab asks for a grade (6, 7, 8 or not sure) and suggests a first lesson. Every lesson stays open, so jump to any track you like. Change grade, on the Learn tab, asks again.

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

Links out of the app (this support page, the privacy policy and More apps) wait behind a quick grown-up check. Pick the right answer to continue.

How do I start over?

Settings › Reset progress erases lesson progress and scores on that device. With players, it asks whose progress first.
