Apps ≫ Abacus Trainer: Learn Soroban

Learn how a Japanese abacus represents numbers, then move the beads yourself.

Follow eight guided lessons covering digits, place value, addition, subtraction, exchanges using five, carrying and borrowing. Watch each demonstration one bead action at a time, then try three checks at your own pace.

Practice with ten-question sessions in Addition, Subtraction or Mixed mode. Start with Foundations for direct bead moves from 0–99, or choose All Basics for numbers up to 999 with exchanges, carrying and borrowing. Hints and answer guidance are available. Results separately count answers correct on the first check and questions where help was used.

Explore the three-rod board in Free Play. Point and click with either Touch controller, undo moves, clear the board and read its value. Adjust board size, text size, sound and haptics to suit your setup.

All eight lessons are included. Progress and your unfinished practice session save locally on your device. Designed for seated or standing use with no artificial locomotion.

English language. Touch controllers required. One purchase, with no ads, subscriptions or in-app purchases.
