The home screen: a 10×10 grid where every fact a child knows by heart is a purple heart gem. A quiz round: 8 × 8 with four answers to pick from, and the child's math buddy cheering. A number boss fight: the boss throws 4 × 7 and the child types the answer. Designing a math buddy: skin tone, hairstyle and colours. The star shop, full of hats, glasses and outfits to unlock.

A grid that fills with hearts

Every fact a child knows by heart becomes a heart gem in the 10×10 grid, so progress is easy to see for children and for parents.

Calm daily practice

Short multiple-choice rounds with no visible timers. Spaced repetition brings back the facts that need more practice.

Ten number bosses

Learn a whole table to unlock its boss. Type the answers before they land and, with no more than one miss, steal its crown. Prefer a gentler pace? Turn on calm boss fights.

A buddy that’s all theirs

Children design their own math buddy and spend the stars they earn on hats, pets, outfits and new worlds.

Private by design

No ads, no in-app purchases, no accounts, no tracking. Nothing is collected and the app works fully offline.

English and Norwegian

Switch language any time in Settings. Up to four children can each have their own profile on one device.

How children learn the times tables by heart

No ticking clock in everyday practice. Just a few calm minutes a day, with the practice going where it helps most.

  1. A short round each day

    Ten to twelve multiple-choice questions with no visible timer. Children answer at their own pace.

  2. The app remembers

    MathMatrix keeps track of every fact and brings back the tricky ones, a method called spaced repetition. Facts that stick come back less often.

  3. Facts turn into heart gems

    A fact known by heart becomes a heart gem in the grid. Learn a whole table and its number boss is ready to fight.
