### 5/5 — とうとう購入！

*2026-06-29*

2年くらい無料で使わせていただきました！
広告も小さくてあまり気になってなかったんですが、音声が出る広告が入るようになったのをきっかけに、300円支払って購入しました！
買って後悔はありません。笑
フォントが小さく見づらくなっちゃったな…と思ったら、ちゃんとメニューからフォントの大きさも調整できます。老眼にはありがたいです。笑
今までタダで使わせてくださりありがとうございました。
これからも良いアプリを開発して下さい😊

### 5/5 — 計算式を編集出来る！

*2026-05-18*

一度計算した式を後から修正して再計算が出来ます。またクリップボードから計算式をペーストして、修正して再計算することも出来るので無敵です。

### 5/5 — 痒いところに手が届く

*2026-01-03*

テキスト計算なので、カッコをつけ忘れた時には後で付けられて、過去の計算式も消去しなければ見れるし、コピペも出来るし、通常の計算機アプリでは出来ないことが出来る！のが気に入ってます。
ずっと無料版を使っていましたが、有料版でも300円（安！！）だったので、作者様に還元したくて購入しました。
カラーもフォントサイズも変えられるし、00の位置も変更可能。時間計算まで出来る！
他の計算機アプリ使えなくなりますね。

### 5/5 — 凄く良いです！

*2025-08-12*

このアプリに出会うまでは、関数電卓を使っていました。(主に履歴とカッコが欲しかった為に関数はほとんど使わないけど・・・)
しかし、このアプリは、自分の欲しい仕様が全て揃っているので、無料版で使用感を確認して直ぐに、作者へのお礼を込めて有料版に買い直しました。
(iPhoneの標準カリキュレーターに満足出来ないなら、是非試す事をオススメします)

### 5/5 — 要望

*2025-04-23*

使いやすいアプリをありがとうございます。有料版にしました。

2乗の計算をすることがよくあります。同種のアプリで、×を2回押すことで計算を素早くできるものがあります。
例 13××=169
という具合です。取り入れて頂けますと大変嬉しいです。ご検討よろしくお願いします。

### 1/5 — Decimal point bug

*2024-11-19*

When i set decimal place to 0 or 00 it reset back to 9 places

### 5/5 — Good calculator

*2024-05-05*

Please, can you change places of “0” and “00” buttons? 
It would be more convenient that way in my opinion. Thanks

**Developer response:** You can change places of “0” and “00” buttons by setting below: MENU(long press)→Settings..→00 key location

### 5/5 — 还不错

*2024-04-20*

使用还不错

### 5/5 — 修正

*2024-02-17*

コピーして貼り付けての繰り返しすると先に貼り付けした数字が消えてしまう

### 5/5 — 使いやすいです

*2023-12-02*

現場でちょこっと計算に使ってます。
