“42” is the meaning of life from HGttG
The number 42 is, in The Hitchhiker's Guide to the Galaxy by Douglas Adams, " Answer to the Ultimate Question of Life, the Universe, and Everything", calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years. And the Wikipedia reveals 42 to be important in most religions. Thus Calc is both powerful and worthy of use.
Beyond the sense of humor of the developer, PCalc is my go-to calculator for everything beyond basic arithmetic. It’s also easy and great for basic arithmetic, but it feels like using a Shelby Cobra racing car to go to the grocery store. It is very customizable, and the colors available make the keyboard more readable and usable AND attractive, rather than the “designer” keyboards that blend all the keys together graphically, putting style over function. I like this calculator, and I always have. And I’ve never gotten weird calculation mistakes, like I have with several of the calculators I’ve tried. PCalc is a Keeper.
Excellent app that continues to improve
PCalc is the rare app that manages to add features without cluttering the user interface or getting in your way. I was a satisfied customer when I first bought it at Version 1, and I'm even more satisfied now.
PCalc's list of features—unit conversions; base conversions; built-in constants; RPN mode; multi-line display (with your choice for the value of "multi"); user-defined functions and unit conversions; and selectable color themes, keyboard layouts, and digit styles—is impressive, but what's more impressive is the care with which they are implemented. The popup indicators that tell you which key you're pressing, the sliding display that stays on screen as you choose a conversion or change a preference, the stack display that also shows you the contents of the memory slots—these are the small things that need to be done right if the features are to be usable. PCalc does them right.
Finally, PCalc lets you create your own custom keyboard layouts. This, combined with user-defined functions and conversions, allows you to turn it into almost any type of calculator you want. You're getting, in effect, an infinite number of calculators.
A few years ago, the batteries in my physical calculator died, and I never replaced them. PCalc is what I reach for.
Superb App! ... and I Like the New Icon, too.
PCalc is the Swiss Army knife of calculators, and I mean that in terms of features, flexibility, and ease of use. It has an exceptional design and implementation that continues to improve over the years. This is a rare app where the new features really add to the usefulness of the product. If I had to buy my apps all over again, this would be the first app that I would buy; honest and truly.
I am very pleased with the new icon because it makes PCalc so easy to find on the screen. It is much superior to the old icon. If you are looking to buy PCalc and reading these reviews, you should ignore comments about the icon, because the PCalc app itself is so worthwhile. PCalc is probably the best value in the App Store. If you buy it, you won’t regret it.
