A zig-zag path from Starter to Grandmaster
Lessons sit on the same path shape as class progress. Your child sees what is next, and stars on what they have finished.
For students & parents
10 minutes a day. Real abacus progress.
Gintoo turns practice into a game — zig-zag path, stars, and Bindu beside every lesson. Sums match what your child has learned in class. No surprises.
Abacus practice that matches class
Short sessions with Bindu beside them — and the same levels and formulas their teacher uses.
Sums that match the formulas they have learned
Direct, small friends, big friends, and combination — never a formula from a higher level. Same engine as printable worksheets.
80 sums in 3 minutes — like real competitions
Timed papers solved mentally. Competition papers are marked on the server; the answer key never goes to the device.
For parents
Built for children — calm for you
Your child practises through their abacus teacher’s class. You get peace of mind; the teacher gets clear reports.
Progress the teacher can see
Accuracy, speed, and weak formulas go to the teacher’s report — so class time targets what your child needs.
No ads. No chat with strangers
Gintoo is a practice app for abacus class. There is no social feed, no open messaging, and no advertising profiles.
Minimal personal data
We store what the academy needs: name, date of birth, username, level, and parental contact for consent — not home address, school name, or photos.
Simple PIN login
Children sign in with a username and PIN from their teacher. No email account required for the child.
One device at a time
A student session runs on one device. Signing in elsewhere ends the previous session — safer for shared family phones.
How to start
Your child's teacher gives them a username and PIN.
Students join Gintoo through their abacus teacher or academy — not by signing up alone. After the teacher records parental consent, your child can log in on the app or in a browser and begin the learning path.
Get the app
Practise on a phone or tablet at home. The same username and PIN work everywhere.
