Customer Reviews

Tried them all; PCalc's the best!

I literally tried almost every highly rated calculator app available, and PCalc is by far the best. For example, only PCalc was well thought out enough to be ergonomically useful on an Apple Watch—the others that I bought were all a fail, because the buttons were too small for reliable use by adult human fingers! The iPhone based PCalc app is similarly well laid out, and completely customizable. Whether you are seeking a very basic calculator or an engineering-level workhorse, this is the best iPhone and Apple Watch calculator that I have been able to find. Many thanks to the developers for making such a wonderful product available.

Best calculator in the App Store

I am a long time user of PCalc. I somtimes check other options to see if I am missing something but so far have not been able to find anything even close.
They are very responsive to suggestions to improve the calculator. The app can be customized to your exact needs. My sister that lives in Venezuela was able to adjust it to use period as thousands separator and comma for decimals. Nice.
Now that I have an Apple Watch I am enjoying it even more. The tip calculator to share a restaurant bill among several people is beautifully designed.
I highly recommend it.

Grows well with your usage

I've been using PCalc on iOS as my primary calculator app for years, where it holds prime home-screen real estate. As a veteran of the HP RPN calculators, I love that it's simple to setup PCalc to obey those many years of motor memory. ;)

One of my favorite features in recent releases are customizable keys. I've set up a few for common operations for a long-running project; those have been amazing time savers.
