### 3/5 — 有料代

*2026-01-04*

500円のはずなのに、600円引かれました。騙されました。

### 2/5 — レスポンス悪い

*2025-03-16*

キーを押したときのクリック音がかなり遅れてくるので、もたつきを感じる

### 5/5 — ネットショッピングの必需品

*2025-01-24*

ネットでの買い物では往々にして「会計時に⚪︎⚪︎％off」と記載されていますが、このアプリではその「⚪︎⚪︎％」をサクサクっと計算してくれるので便利です。
携帯で関数計算までしないのであれば、このアプリ一択で後悔は無いと思います。

### 4/5 — 起動時の設定

*2024-06-08*

起動した時に前回の計算結果が残っているので0にできるようにしていただけませんでしょうか。

### 4/5 — 税込みボタンの改善のお願い

*2023-03-17*

ほぼ完璧でとても気に入っています。
機能アップのお願いで税込みボタンを二度押すと計算結果に更に税込の計算となってしまっているので
出来れば数値を維持しつつ税のみ表示→税込み表示→税のみ表示と繰り返すような方式にバージョンアップしていただけると嬉しいです。
宜しくお願いします。

### 4/5 — 消費税計算はこれ！

*2022-10-28*

色々試しましたが、８％と10％の税込・税別計算はこれが良いです。
税率計算の端数の処理も設定できます。

イコールを押した後に数字を入力すると、数字の続きになります。
例えば
100＋100＝200
の後10を入力すると、新規計算ではなく
20010
となります。
最近の流行りでしょうか、設定で新規計算も選べるようになれば良いなと思います。

### 5/5 — こんな電卓がほしかった‼︎

*2022-08-22*

とても使いやすい。
メモリーも目視できるの良い。

### 3/5 — Nur klitzekleine Schwäche

*2021-12-26*

Absolut top, übersichtlich. Allerdings nervt sehr, dass trotz der vielen Einstellungsmöglichkeiten beim Starten der App immer das letzte Ergebnis noch im Fenster steht und manuell zurückgesetzt werden muss. Macht man das nicht, wird die Eingabe hinter der letzten Ziffer des letzten Ergebnisses fortgesetzt.

### 5/5 — サウンドが鳴ったりならなかったり

*2021-03-15*

不安定

### 4/5 — 良い

*2021-02-18*

使いやすい
