使いやすい

計算履歴が残り、結果もタップすれば転記でき同じ入力をしないでよいので楽で慣れるとスイスイと計算結果をえられます。 使い方の問題ですが、1+2×3のような計算順序の不一致によるミスの場合は1×2=の後×3と入力することで回避できます。(個人的な意見) 1行で終わる簡単な計算はボタンをタップして指紋認証しないでウィジェットで入力! 便利です。

やっと見つけた理想のcalcアプリ

色んなcalcアプリ試してコレ!ってものが見つからず、もう面倒くさいから純正でいいや…って感じだったんですが(笑) ふとこちらの無料版使ったら余りの使いやすさに思わず課金。ますます便利! 機能性だけでなく、シンプルで美しいデザインもまたいいんですよねえ。 超オススメアプリです。

decent basic unique, can save out calculations to other apps

only concern is no developer activity since 2014 October when I first installed.

Chic, aber unpraktisch

Sieht sehr schick aus, ist aber ziemlich unpraktisch. Das Tastaturfeld geht über die gesamte Breite des Bildschirms. Damit sind die Zahlentasten sehr weit voneinander entfernt. Das führt zu Tippfehlern und zu langen Armbewegungen. Damit ist die App für mich ineffizient. Wenn man die Breite des Eingabefeldes ändern könnte, wäre es deutlich besser.

Mein neuer Standardrechner

Toller Rechner, sehr übersichtlich, übernimmt Zahlen nur mit einem Tastendruck und vor allem für mich war wichtig: % und ( ) ohne umschalten zu müssen. Sehr empfehlenswert.

便利

日々の積算に使っています。記録が複数残せるので便利。清楚なアイコンも気に入っています。仕様もデザインもセンスが良い。

いい

前の計算式が見れるので便利です
