Description

SlashFacts is a multiplication-tables trainer (2 to 9) built around a single gesture: you answer by drawing one continuous stroke through the digits of the result. No buttons, no rewards, no screens between attempts — see → remember → slash → next.

  • Pick the tables to practise, and each round adapts to the facts you keep missing or answer slowly.
  • A missed fact shows its answer and comes straight back until it is answered right.
  • The Facts map ticks every fact answered right first time — one mark a child can read at a glance.
  • Haptic feedback on every answer, fully usable offline.

Designed for children: no account, no network access, no analytics, no ads. Everything stays on the device.
