Math facts that stay learned.
Most drill apps stop at "got it right once." Ours keeps checking — quietly, at growing intervals, for as long as your kid uses it — because mastery is a maintained state, not a box you check and forget. An automaticity-gated drill built for homeschool families. Free during early access.

Fact 1 of 8
Built differently, on purpose.
Three deliberate choices that shape everything else about the drill.
No countdown clock
The engine measures response time silently, the same automaticity gate that already runs on our language courses. Your kid answers at their own pace — no visible stopwatch, no ticking clock, no race. Speed is data we watch, never pressure we apply.
Facts that stay learned
A "mastered" fact doesn’t retire — it keeps getting checked at growing intervals, for as long as your kid uses the app. That’s the summer-slide antidote: the system notices a fact going stale and quietly brings it back before it’s actually forgotten.
No coins, no pets, no shop
No engagement economy standing between your kid and the facts. The reward is real fluency — and what you see as a parent is honest numbers: which facts are automatic, which are going stale, and how many minutes this week. Nothing to trade, nothing to farm.
How it works
You'll also get a parent dashboard — a fact-by-fact grid of what's automatic and what's going stale — plus a weekly email recap, so you always know where things stand without watching over a shoulder.
Learn the strategy
Each fact family opens with a short strategy card — doubles, make-ten, counting on — so your kid learns a way to think about the facts, not just the answers.
Drill it on the number pad
Big touch targets, typed answers, instant feedback. A wrong answer gets one retry before the correct answer is revealed — no dead ends, no shame.
The engine holds it to instant recall
A fact only becomes "mastered" once it’s answered both correctly and fast — the same response-time gate that powers automaticity in our language courses.
It stays in rotation for life
Mastered facts don’t disappear from the queue — they resurface for a quick check at longer and longer intervals, forever, so they never quietly fade.
