A look inside KingMath

These are real screens from the app.

KingMath levels M1 to M33

Six levels, from times tables to 3×3

Children begin with memorising the tables (M1) and move up to 3-digit by 3-digit multiplication (M33). Each level has its own practice modes.

Column multiplication with carry marks

Column multiplication, shown step by step

Carry marks, partial products and the final sum are laid out the way children write them in school.

Competition screen with levels

Competition and leaderboard

Children pick a nickname, pick a level and compete for a place on the leaderboard.

Our approach

Useful by design. Built around real needs.

1

Start from real needs

We pick topics students and parents actually struggle with.

2

Simple and clear

Large buttons, clear steps and no clutter, so children can focus.

3

Learn and improve

We listen to feedback and keep improving each app.

4

Built with care

Made for children, with parents in mind.

Who we build for
