Algebra kids learn hands-on.
Equations become blocks on a balance. Take two from one side, and the scale tips until you take two from the other. Children work out x by moving the pieces themselves.

Keep both sides equal. That one idea is all of algebra.
Every chapter is the same honest loop: see the equation as objects, make a move, watch the balance react, check the answer in the original equation.
1Feel the balance
A five-step hands-on introduction. No reading required: drag, watch the scale tip, make it level again.
2Find x by hand
Remove, add, split or copy. Whatever you do to one side, the other side asks for the same move. Undo is always one tap away.
3Grow into bigger numbers
Later chapters bring tens rods and hundreds cubes, so 8x + 356 = 700 is still something you can pick up and exchange.
Ten chapters, two hundred puzzles, one balance.
- Chapters 1–3Add and subtract to isolate x
- Chapters 4–6Multiply, divide and share equally
- Chapters 7–8Two-digit numbers with tens rods
- Chapters 9–10Hundreds cubes and exchanges
- Create a puzzleBuild your own equation and explore it
- JourneyA map of islands that shows progress at a glance
Counting chapters for younger learners (ones, tens and a hundred cube) are in development.
Built the way we would want an app built for our own kids.
Nothing leaves the phone
No account, no email, no sign-up. Progress and settings are stored on the device and nowhere else.
No ads, no tracking, no purchases inside
One small price on Google Play. There is nothing to unlock, no timers, no nagging.
Calm by design
Night mode, a calm-motion switch, sound off, large touch targets, and a mascot that cheers but never interrupts.
Settings adults can trust
Night mode, sound, calm motion and hints on one screen; privacy policy, support and reset in the same place. A separate grown-ups area with per-child progress is in development.
Honest maths
Every answer is checked exactly on the device. Division is shown as equal sharing and multiplication as copying the whole side, so the picture always matches the maths.
Works without internet
The whole app is on the phone, so it works on a plane, in the car or anywhere with no signal.
