Лучший

Самый лучший калькулятор! Быстрый, с историей и возможностью писать выражения со скобками. Есть небольшой баг с прокруткой истории в новых версиях iOS, но, всё равно пользоваться можно :)

Все бы такие программы делали! Прямо с душой...

1番使いやすい

3GSの頃からずっと使っています。1番使いやすい電卓アプリだと思います。有料でも良いので更新を続けて欲しいです。

thx :-) RET RET RET ... plz

I've been using it for 10 years, and I'm grateful for this great free app that traditional hackers love.

The only thing I think it's missing is the ability to reuse formulas like in the history.

I think it would be nice if you could load previous formulas by pressing ret.
