Abacus' brain Lite
By POPPO STUDIO
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.
What's New in Version 2.1
iPhone6, iPhone6 Plus compatibility.
Useful but Frustrating.
This app isn't very user friendly. Once the game or practice starts. There is no way of exiting the app until you complete the challenge. If you get stuck or lose track of what number you're on, you must force quit the app just to start over. This is incredibly frustrating. Please add proper navigation menus. Back buttons and exit buttons would be great.
