About SlashFacts

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.
