### 4/5 — 配色が変わって残念

*2026-03-23*

とてもシンプルで視認性も良く、使いやすくて重宝していたのですが、アップデートしたらカラーリングが変わってしまいました。
グレー背景に白ボタンのシンプルな設定を愛用していたのですが、続けて2つ以上の計算をしたときに表示されるログ部分で、数字のところが黒字に白抜きになってしまって、非常に目に痛いです。
以前の、白地に濃い字で数字が書かれている方が目に優しくて良かったです。
その点以外は、とても素晴らしいアプリです。けれど今の配色では目がチカチカして疲れてしまうので、他のアプリを探そうと思っています。

### 5/5 — 可愛い

*2019-04-04*

カンマの選択や、左寄せ、配色変更や、事前の計算式もみれて本当に便利です。
ただ一つ残念なのが、前のシンプルなアイコン（茶に白文字だったかな）の方がホーム画面にあっても可愛いくて好きでしたー。

### 5/5 — これしか使いたくない！

*2017-11-25*

最高に可愛いく、使いやすく、素晴らしい電卓です。前の計算が表示されるという機能がとても良い！ デザインも素敵で電卓の着せかえ・数字ボタンの色の配置がえなどができます。そして広告もない。使うのが楽しいです。電卓アプリはこれしか使いたくないです。★が5個では足りないです。これからもずっと使わせていただきますね♪ 本当にステキなアプリをありがとうございます。

### 2/5 — まさか今更アップデートするとは…

*2016-09-27*

何年も放置だったのに今さら変わられると使いにくいです。
タイトル画面が出てくる分
起動も遅くなったみたい。
色も以前はふんわりしてたのに、やたらビビットになって起動するたびにうんざり…以前のものが使いたいです。とても便利な電卓なので。

### 3/5 — 私も

*2016-09-24*

アイコンが変わってしまい残念です。。今までの感じの方がシンプルで可愛かったです。

### 3/5 — 今までの方がよかった

*2016-09-22*

とても使いやすく気に入ってますが、バージョンアップでアイコンが画面がうるさくなってしまった。電卓の色が変えられるのはいいけど、アイコンは今までのようにシンプルにしてほしい

### 1/5 — なんでデザインかえたの？

*2016-09-22*

前ので良かった。一気に子供っぽくなってしまった。アップデートしたくない…

### 3/5 — デザイン一新とは言うけれど

*2016-09-20*

前のデザインが良かった。選択で今までのも選べたらよかったのになぁ。

### 5/5 — ずっと待ってた！

*2016-09-20*

シンプルで可愛い電卓。アップデートありがとうございます！ずっと消さずに待ってました！！

### 1/5 — なぜ？

*2016-09-20*

アプデしたら設定画面完了出来ない、、、電卓使えなきゃなんの意味もない
