### 1/5 — てねそののく

*2017-12-10, version 1.46*

まきたこやち

### 1/5 — Missing %

*2017-09-12*

How do you guys make a calculator app and not have % it's useless

### 5/5 — 結果と式が見れるだけでこんなに便利になるとは！

*2017-06-27, version 1.43*

標準の電卓に計算結果の履歴と、計算中の式を確認できる電卓。
機能としてはとてもシンプルだが、これらがあるだけで、利便性が全然違う。電卓をよく使う人にも、あまり使わないけど標準の電卓だと物足りない人にもオススメ

### 3/5 — Great Calculate but too many ads

*2017-05-20*

The calculator is great and offers features that other calculators do not. However, it's really hard being in the middle of trying to add up your finances, or bills, and you keep hitting the screen that causes an ad to pop up.  I would be willing to pay more to get rid of the ads. No one wants to see ads when frustrated calculating bills.

### 4/5 — 使いやすい

*2016-12-14, version 1.2*

長い計算途中に間違えた時にすぐに修正できるから便利です。

### 5/5 — 使える！

*2016-11-19, version 1.0*

シンプル。計算した答えをメモせずにすぐ使えることが便利で普段からこのアプリを使ってます！

元から入ってる電卓アプリのほうが起動しやすいことが残念。
でもこれからも使います！
