The best at what it does

This has been my favorite calculator app on iOS for some time, and it’s just as amazing on OS X. If you’re a programmar or engineer, this is the calculator app you want. No frilly graphs, no silly hand-writing recognition nonsense, this is a calculator for geeks, made by geeks, that’ll do what cool people want to do!

Whether it’s awesome RPN, groovy themes, customization that will blow your mind, a multitude of base systems supported, or whatever, it does it and it does it well.

No, I don’t work for these guys, but I do love their calculators so much, and this version is no exception.
