Emma unlocked multiplying fractions this week. “Mom, this is actually easier than regular multiplication.”

What makes us different

Three promises. We won’t move them.

01

We teach the trick, not the trick answer.

Wrong answers get a worked explanation. Right answers unlock the next skill. No stars, no candy.

02

Progress only goes forward.

No score that drops. No mastery taken back. If your kid plateaus, we quietly re-teach the prerequisite.

03

Parents see everything. Kids are never up-sold.

No ads. No in-app purchases. No coins. You see every skill, every week, in one email.

Hint from Numi

Eight is the same as 8/1. Multiply straight across, then simplify.

Why we built this

Three things that actually matter

Most math apps chase the wrong thing. These are the three we refuse to get wrong.

Adapts to your child

Bayesian Knowledge Tracing keeps problems at the right difficulty. No frustration, no boredom.

Progress only goes forward

No scores that drop. No stars taken away. Wrong answers show the solution with a gentle explanation.
