## What is Abacus' brain Lite?

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.

### 2/5 — Useful but Frustrating.

*2015-12-12, version 2.1*

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.

### 1/5 — 脳活

点滅が気になります。
いくら、初心者向けでもこれはひどいと思います。
本物と全然違うし、このアプリをきっかけにそろばんをやり始めたとしたら全然できないと思います。

もっと、本物っぽくスムーズにできるようにしてみては？

### 5/5 — 完全初心者ですが

*2014-04-05, version 1.2*

いいですね。最近そろばんに興味が出て、触ってみたいと思いインストールしてみました。単純で分かり易いし反応も良い。入門にぴったりではないでしょうか？
音も光も本体で操作操作出来る訳ですから、特に問題と感じませんでした。無料ですし＾＾　
点滅で眩しいという人は、ディスプレイ設定が明る過ぎるのでは？

### 5/5 — そろそろバンバン
