### 3/5 — 戻るボタンがあればもっといい。

*2024-11-26*

買わないと分からないので買ってみました。戻るボタンがないのが残念です。何行か打った後に、あ、ミスった！と言った場合、ACしかありません。
まさしく、「ふりだしに戻る」です。履歴が表示される電卓だからこそ、戻るボタンが必要です。要望としてお願いしたいです。

**Developer response:** レビューありがとうございます。
入力の後、”C（クリア）”を一度押し、再度入力すると普通に継続して計算できます。
”AC”を押してしまうと、リセットされますのでご注意して下さい。
戻るボタンは”C”で良いのではないか？と思いつけておりませんが、今後の参考にさせていただきます。

### 1/5 — Was stimmt hier nicht

*2022-11-30, version 4.2.0*

Wenn ich rechne 100+19%= sollte nach meinem Verständnis 119 rauskommen und nicht 100,19. für mich so nicht brauchbar.

### 1/5 — 1文字消せないので注意

*2021-08-19*

二つ計算確認できるのは良いが、入力ミスして1文字消す「←(bs)」ボタンはありません。なので2画面でボタンが小さくなる際に入力ミスすると計算はACかCを押して，1からやり直しになります。

**Developer response:** スペースの問題もありますが、検討させて頂きます。
ご意見ありがとうございました。

### 5/5 — 色

*2020-02-25*

2つの計算を同時に表示できる電卓を探していました。以前はとても気に入っていたものがあったのですが、機種変してからダウンロードできなくなってしまって…。　電卓の機能的には可も無く不可も無くですが、画面の色が立ち上げる度に黒に戻ってしまう所が不満です。せっかく色の選択肢があるのだから、固定できれば十分満足出来きるアプリです。

**Developer response:** 遅くなりましたが、データの永続性を追加致しました。これにより、毎回リセットされる事はありません！また、追加機能もあります！！
よろしくお願いします。

### 1/5 — Gute Idee aber funktioniert nicht richtig....

*2019-09-18, version 2.3.0*

Erst dachte ich bin zu blöd...
Aber andere bekommen auch keine passenden Ergebnisse mit der % Taste raus... da ist irgendwas falsch - wer die nicht braucht bekommt einen Rechner der sonst funktioniert...
Leider kann man den Entwickler nicht erreichen... kein Support...
Schade...!

### 4/5 — Лого!

*2018-11-24*

Калькулятор очень удобный, не надо прерывать расчетов, достаточно посчитать на соседнем и вернуться с результатом к первому) класс! Ребята только сделайте ЛОГО КАЛЬКУЛЯТОРА ПОСОВРЕМЕННЕЕ ПО ТИПУ ОРИГИНАЛЬНОГО!!!!!! Ярче!
