### 5/5 — Great

*2019-12-30*

Calculates immediately.  Thanks.

### 3/5 — 希望

*2018-09-07*

角度を万分の1
数字の配置を電卓と同期。

お願いします。

### 5/5 — 64bit対応ありがとうございます

*2017-09-30*

ios11で使えなくなるのかと思ってましたが、64bit対応されていたので安心しました。
またしばらく使えます。
機械系製造業にはかなり重宝するツールなので、助かります。

### 5/5 — 64bit対応してください！

*2017-07-19*

32bitままだと、iOS 11以降に使用でしかなくなるかもしれません。
主に仕事で使うので、使えなくなるとダメージが大きいです。
64bit化お願いします！！

【追記】2017年7月14日のアップデートで、64bit化されました！
ありがとうございます！

### 4/5 — 仕事で重宝してます

*2017-06-01*

ぜひアップデートお願いします

### 5/5 — このアプリは

*2017-05-09*

とても素晴らしい！
配管の角度計算で使いますがかなり重宝してます！
是非アップデートを！！

### 4/5 — 度分秒があれば…！

*2016-12-04*

以前は「三角関数calc」というアプリを使っていました。とにかくこのアプリが便利で助かっていたのですが、機種変更したら使えなくなり、こちらに移行しました。
仕事柄角度を度分秒で使う事が多いので、こちらのアプリだと電卓で角度を度分秒に直してから使わねばなりません。しかしこの手間が煩わしい。度分秒に対応していただけると助かります。

### 5/5 — 楽チン

*2016-05-30*

機械加工でチョットした計算の時に役立ちました。
スマホで簡単に確認できる事が便利です。

### 5/5 — Very good!!!

*2014-12-13*

My grades went up sooooo fast!!!!!! Thank you!

### 3/5 — いいのですが、、、

*2014-11-07*

できれば1:0.1などの単位の計算にも対応してもらいたいものです。
