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.

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。
