Math practice that actually sticks.
Short daily lessons, adaptive difficulty, and spaced repetition — built around the Math Kangaroo curriculum, from first grade through senior year.
Adapts to you
Every question's difficulty tunes itself to your current skill, so lessons stay challenging without ever feeling impossible.
Spaced repetition
Problems you're shaky on resurface right before you'd forget them — the rest make room for new material.
Streaks & XP
Daily streaks, XP, and hearts keep practice consistent — the same way it works in the Kanga Routine app.
Class leaderboards
Teachers create a class and share a code. Students join and compete on a leaderboard scoped to just that class.
Privacy-first
No real names or emails are ever shown publicly. Kids' accounts never collect personal info — see our privacy policy.
