使いやすくて安い

めちゃくちゃ使いやすいです!
そして、毎月のサブスクかと思ったら、買い切りの300円・・・!これは安すぎて有難いです。

More useful than most calc apps these days

It seems that many calculator apps these days have been infected with PEMDAS equation order of operations. PEMDAS is good for academia, but it isn’t useful in the real world where it is more common to need running totals. With SimpleCalc, you don’t have to worry about equation formulation just to get the answer you need. This app just works.
