### 2/5 — iPad使用時画面フルにならず…

*2026-01-18*

無料版を使わせていただいていましたが、広告がうるさいので有料版を購入しました。無料版はiPadの画面フルで使えるのに、有料版になるとiPad画面の1/3しか画面が表示されずiPhoneと同じスペースしか使えない…。無料版でできて有料版でできない(画面が小さくなる)のが理解できない。iPadのバージョンの問題なのでしょうか？課金したのに残念でした。

### 4/5 — iPadではslide overでよく使います。

*2025-11-05*

幅をを細くしたり、高さを変えられたりできたらいいなと思います。是非お願いします。

### 5/5 — It’s awesome!

元にもどしてください

### 1/5 — 使いづらくなって困る

*2024-07-09*

アップデート後、画面が拡大されて入力ボタンが見切れている。押しづらい。
アプリを開くと数字を入力する所がプルプルっと震える。計算する時急ぐので無駄な動きは排除してほしい。
以前の感じで必要十分 使いやすかったので戻して欲しいです！

### 1/5 — 勘弁して欲しい

*2024-06-19*

アプリを開くと、数字を入力する枠がフルフル揺れる。
視差効果はほんとやめて欲しい。酔う。不快で吐き気を催す。

### 1/5 — プルプルは目障り

*2024-06-17*

これは注意を取られて、邪魔。
こんなのを良しとする程度の奴らが作っているということ。
削除した。

### 3/5 — アプリ画面が拡大されてしまう

*2024-06-14*

アップデート後iPhoneの設定を文字を拡大にしているとアプリ画面が拡大されてしまい画面に収まりません

**Developer response:** 拡大表示の際に電卓が画面内に収まるように修正をいたしました。

### 4/5 — Please change back!!!

*2024-06-12*

Please change it back to how it was!!! This new version is not that good! Thanks
