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.

"All I want and more in a very readable interface."

August 17, 2011  |  By Steveg_VA

 |  Version: PCalc 3.7


Much more than just a regular and scientific calculator: things like financial and trigonometric calculator faces. Many included customization skins. All kinds of conversions between various systems of units are built in.


The only conversion that I use often and that is missing is currency conversion, which is available on Apple's included OS X Calculator. But, the interface is much sleeker. Come to think of it, there is no religious conversion function, either <g>.


More reminiscent of the pocketable Texas Instrument and HP calculators of days gone by (does anybody carry these anymore?), and for $10, it's a steal.
