Practise the right maths, not just more maths.

Every topic, P1 to P6
From basic addition to percentages, speed and 3D shapes. Each question is written for one topic, never pulled at random.
Hints, not answers
A wrong answer brings a hint, not the solution. Mistakes come back later for review until they stick.
Not just sums
Shapes, charts, measurement and direction questions that need a picture — the kinds found in real school papers.
Daily speed maths
100 quick calculations a day, the same set for everyone in the grade. Scored on accuracy and speed against a target — no leaderboards.
See the weak spots
A PIN-protected parent area shows what your child did, which topics are weak and recent mistakes. Optional daily email.
Chinese, English or both
Set per child. One tap switches the current question to the other language.
Everything is free
Step-by-step solutions, redo mistakes, daily speed maths, parent reports and daily emails — all free. No ads, no in-app purchases, no account. Learning records stay on your device.
