Abacus' brain Lite


Open iTunes to buy and download apps.


The mental calculation speed rapidly becomes early by putting the abacus in the head.
This software is an application program that sequentially adds ten figures that appear one after another, and becomes familiar with the abacus.
The level of the sense from 1 digit and 3 seconds to 0.5 seconds is prepared in the Lite version. Where can you calculate?
The mental calculation mode is prepared of course, and calculate with an abacus in the head, please. The flash mental calculation is not a dream.

Customer Reviews


This is the best soroban app that I have looked at and I will certainly purchase the full version. In this version you are only limited to single digit multiplication (1-9) however the graphics and performance of this app is really great. It is fast and responsive even for two fingered gestures like setting the number "6", just like I do on my real soroban. Good app.

Great App

Works great, lots of fun, hope the full version is as good! Thank you!

Dangerously loud

It is far to loud and the sound is not easily configurable.
