使えなくなったら困る

アナログの電卓だと、計算式は消えて答えだけ残るのですが、このアプリなら計算式と答えが一緒に履歴に残るので、とても助かります。
履歴は、自動では消えず、自分で消さないと残り続けるという点も、とても気に入っています。
消費税の計算（パーセント）も簡単に出来るので、発達障害持ちで暗算（計算）が苦手な私は、手放せません。

使いやすすぎる！

長らく無料版を使わせていただいていたのですが、こんなに使いやすいアプリを作っていただいたことに報いたくなり、有料版を購入しました。
めちゃめちゃ使ってます。
履歴が残るのとコピーができるのがすごく助かっていて、もうこれ無しじゃ満足できない体になってしまいました🫨本当にありがとうございます。
少しですが美味しいもの食べてください。

Rapid & Quick Calculator Pro

This is one of the very best calculator apps that I’ve ever used. It’s very easy and simple to use and has a running history of everything you’ve done. I would certainly recommend it to anyone looking for a calculator with history.

計算式が表示され続けて、使いやすいです。また計算結果もたくさん表示されて便利です。

使いやすい

いろんな使い方が出来て使いやすい。式をコピーしたり、複製して編集したり、、、
強いて言うなら、計算式の窓（表示）を画面大にできると、もっと使いやすい。ちよまっとした計算式なら良いが長くなると見にくくなるので。
