PCalc: A Stylish and Full-Featured Scientific Calculator App

PCalc Icon

Looking for a good scientific calculator that your kids (or roommate) won’t make off with, because it’s downloaded as an app to your iOS device? (Which your kids or roommate might also abscond with, but still….)

PCalc is a beautifully-designed, dynamic calculator for iPhone and iPad, available in the App Store. Below I review the definitely-worth-its-$9.99 app. There is a free, “lite” version available here.

PCalc functions with zero lag, and has a really nice layout, which you can change to suit your preferences:

I liked that view so much I didn’t even think to look for different display options till weeks later. But then I found this:

The developer describes the app thus:

PCalc is ideal for scientists, engineers, students, programmers, or indeed anybody looking for a feature-rich calculator for the iPad, iPhone, or iPod touch.

It includes an extensive set of unit conversions, a paper tape, an optional RPN mode, engineering and scientific notation, as well as support for hexadecimal, octal and binary calculations.

My favorite feature–that I’ve not seen in any of the other five or six calculator apps I had downloaded and promptly deleted from my phone–is that PCalc can run conversions for you: currency, in the kitchen (good for those of us who still can’t go fluid ounces to cups, which is ALL of us), energy units and more.




Listening to the new Kendrick Lamar, I might want to know how many square miles 40 acres is. With PCalc, I have my answer within a few taps:




It has a bunch of Constants stored, to which you can add your own:






There are also a ton of functions this app can perform that I probably would have loved in my high school Calculus class, but would have trouble with now. You can do more when you rotate to landscape mode:

Note the Ticker Tape underneath the number up top… that’s your computation history! You can even swipe back from the results screen to have PCalc re-perform your last operations.

This is a highly advanced calculator. I can’t say whether science and math students can put away their TI-80-whatevers, but they should at least download PCalc first.

Need to quickly figure a tip, or something else? Without even unlocking your device, swipe down to the Today view and find the best-looking, most functional widget you’ll probably see on iOS 8:



Even Apple’s own Calculator app does not have access from the swipe-down Today view.

PCalc is a fantastic app, and the last non-graphing, scientific calculator app you’ll ever put on your phone. See the full feature list here, and look at many more screenshots here.



Thanks to TLA Systems, the makers of PCalc for iOS, for giving me a download of the app for this review. See my other AppTastic Tuesday reviews here.
