Customer Reviews

Excellent calculator/converter

As a longtime user of PCalc on the Mac, I was glad to see that they had an iOS version. With the optional conversion pack, this does any sort of calculation I need, with a clean interface that makes everything accessible without any clutter.

Well designed

Admittedly I only use it's simplest features, but it is nicely designed and provides RPN which feel natural to me.

Very clean interface

Very good looking app but please change the app icon design. Or at least the color. Looks ugly.
