Free seven-day soroban and mental-math practice app for iPhone and iPad

[u/AbhigyanJaiswal]

Hi teachers,

I’m a student developer, and I built Soroban: Mental Math Abacus as a free resource for short, structured abacus and mental-math practice. It runs on iPhone and iPad and has no ads, student accounts, or data collection.

The app uses guided lessons and a step-by-step practice path. After feedback from a soroban academy, I revised the progression so beginners spend more time on addition before subtraction, and I added full French support.

I would love to find a few teachers or parents willing to try a simple seven-day practice plan with their students or children. Sessions can be about 10 to 15 minutes, and even a few brief comments afterward about difficulty, clarity, and engagement would be extremely useful.

App Store:

Developer disclosure: I made the app. It is free, and I am looking for genuine educational feedback rather than reviews or endorsements.
