Practice chosen from evidence, not a fixed worksheet

Flash Cards and Beat the Clock draw from the same learning state. Playing either mode contributes answer evidence, so the learner does not maintain separate progress for each game.

A multiplication relationship is practised as a product, a missing factor, and a matching division. For example: 7 × 8, 7 × ? = 56, and 56 ÷ 7. Each form keeps its own evidence because strength in one form does not guarantee equally quick recall in another.

The scheduler balances overdue reviews, weaker knowledge, recently missed facts, and a controlled amount of new material. A missed item can return sooner, while established facts are given longer gaps between reviews.

Strength is an estimate derived from answer accuracy and speed. Review timing is tracked separately so the app can suggest what to practise next without making a strong fact look weak merely because it is due. Strength is not a school grade, diagnosis, or promise of future performance.

The app saves progress in the browser and offers export and restore tools. Optional sign-in can connect progress to an account for synchronisation. The privacy policy explains the corresponding data flows.
