Four parts, one tight loop: practice the right facts, track mastery, report it in plain English, and keep kids coming back.
The session loop is monastic by design: a single fact at a time, a clean answer pad, instant feedback. Fluency is measured invisibly — the timer never shows, because anxiety is the enemy of fast recall.
The benefit: reps that feel like a game, not a test.
Every fact is a node that fills gray → amber → green. A fact turns green on the "three threes" rule — correct and fast enough, three times running, across at least three different sessions. The map is the home screen, the reward, and the report card at once.
Operations appear on the map as they're introduced, so a kindergartener's map isn't a wall of facts they've never met.
Parents see one child's map, streak, and a plain summary. Teachers see the whole class — a sortable roster and a group heat-map showing the percentage who've mastered each fact, so you know exactly what to reteach.
The benefit: know where every student stands in seconds.
Fluency demands repetition, so repetition has to reward. Daily streaks, personal bests, and a map that visibly fills keep kids choosing to play — collaborative class goals, never a leaderboard that shames the strugglers.
On the roadmap after launch: collect & mix creatures as you master facts — the move the Mixto name promises.
"Fast enough" starts grade-appropriate and ratchets down toward the gold-standard 3-second recall (3.5s for division) as kids grow.
Every session is 65% facts they're closest to locking in, 20% newly introduced, 15% already mastered for confidence.
Short, consistent reps build durable recall better than one long session.
Free trials at launch: 7 days for parents, 14 for teachers.
