## What is Soroban Abacus Dojo?

A real abacus you flick with your finger. The beads click into place right on screen. From basic practice to mental math training, you can keep it all going in one place.

The menu is laid out like a dojo.
- Abacus practice: flick beads freely on a 13-rod board
- Flash anzan: add up numbers that flash one after another
- Column addition: work through stacked numbers
- Read-aloud: solve along with the spoken calls
- Grading exams: take on 10 questions and rank up
- Records: track your streak and accuracy on a graph

Problems adjust to your level, from beginner up to advanced ranks. Every day of practice stays in your record.

No ads. No network. One-time purchase. Available in English and Japanese.
