Editors' Review


PCalc is a high-powered scientific calculator that goes beyond the features found in the built-in Mac OS scientific calculator. Scientists, mathematicians, or just serious students will find quite a few bonus features comparable to those found in standalone programmable scientific calculators which PCalc's interface mimics--including quick one-key conversions, constants organized by field (from astronomical to physicochemical), an optional RPN mode that matches modern calculators, and decimal, hexadecimal, octal, and binary modes. You can also write your own functions and conversions, maintain multiple calculators (all with different states), and use PCalc's slightly lower-powered Dashboard widget for quick calculations. PCalc even comes with a virtual tape, so you can look through all your past calculations, and you can resize and skin your calculator with a variety of themes.

This shareware app is also available as a cheaper (and very similar) iPhone and iPad app, and the Mac version has been updated to add more of its features. If you regularly use a scientific calculator, you should definitely check out PCalc, on any platform.

"Super software and superior to what comes with the Mac"

August 06, 2010  |  By tmularz_dotmac

 |  Version: PCalc 3.6


I like the color variations, the "tape" capability, the simplicity of functions, graphic design, and use from the Dashboard.


Haven't found anything I don't like yet.

"I thought that Mac was a academic product!?!"

August 05, 2010  |  By peckdev

 |  Version: PCalc 3.6


it's better than the calculator that comes with the Mac OS... that's about all for Pro's


it costs money! I would imagine every student needs a good calculator for school. Why is the Apple tax so much?


I have both a Mac and a PC, and if I wanted to switch to a Mac only it would cost me a fortune to get the necessary software for college. A Windows 7 machine as much more freeware available for academic use. I spent $1700 on an iMac, and would need to spend another $600 on software that is free for a PC.
