A complete abacus academy for children. Animated beads teach the why, guided practice builds the habit, and Flash Anzan turns it into speed. Teachers and parents get the full picture.
Beads move to the bar. What touches the bar is the number.
Ten lesson types per level, in a fixed arc that moves a child from understanding to speed.

From the very first bead to competition-pace Flash Anzan.

Advanced speed calculation
Every calculation is shown on a real soroban, one bead at a time, with the carry and the borrow highlighted exactly where they happen.
Accuracy, speed and mistake patterns feed a difficulty engine. Struggling gets easier reinforcement; thriving gets harder challenges.
Adjustable digits, term count and display speed down to 150ms. Full-screen, distraction-free, with countdown and score screen.
Stars, daily streaks, achievements and daily challenges - tuned so accuracy always beats rushing.
Class analytics, per-student deep dives, weak-topic detection, assignments, timed tests and CSV export.
A calm summary of what your child practised, what they mastered, and what needs a little more attention.
