PCalc - The Best Calculator

By TLA Systems Ltd.

This app is only available on the App Store for iOS devices.

Description

PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator. It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations.

Includes an Apple Watch app, so you can calculate on your wrist!

What's New in Version 3.7

Added full support for iOS 11, including drag and drop support, and even a (silly) bonus AR calculator mode in the About screen in the Help.†
Support for the iPhone X.
Completely rewrote the display code. Many exciting things to come later which are now possible because of this, but some changes today!
You can now adjust the size of the digits in the display, and make them much bigger or smaller.
You can now use a space for the thousands separator.
Hex, octal, and binary numbers are now grouped using spaces on the display.
You can now have lines displayed in two columns on a horizontal iPhone or iPad.
You can now edit and reorder the list of favorite currencies.
Added a arbitrary base "Log N" button to most of the advanced layouts, and you can edit other layouts to add one.
Added a variety of new digit styles.
Added an option to use haptic feedback for buttons in the "Key Click" section of the settings.
Added an edit cursor option to the Accessibility section.
Fixed a crash if you pressed on a conversion, function, or constant category name while editing.
Fixed a display problem with the tape and the "Show implied parentheses" option.
Fixed a problem with the normal layout being reset if you opened the app in splitscreen.
Added a few more alternate icons, for old times' sake.
There might be a small game in the About screen too.†

† The fancy 3D/AR About screen needs a recent device that supports Metal, ideally an iPad Pro or an iPhone 7/7+ or later. The 3D stuff requires iOS 10, AR support requires iOS 11.

Best Calculator App, Period.

This thing is the Disneyland of calculator apps. The developer is a genius. Every feature you could possibly want, or might one day in the future discover you want, is in here. But none of that vast array of features results in any unnecessary complexity. PCalc is totally user customizable, enabling you to create just the feature set and look and feel that you desire.

Also, every other calc app I have tried has either lagged or mis-registered touches, but PCalc is smooth as silk, which is crucial for a calculator. I never thought I would even review, much less rave about a calculator app, but not only does PCalc work like a dream, but it has such incredible attention to detail and customizability that it's actually a ton of fun just to play around with the endless variations.

But wait, there's more. As if this thing couldn't possibly get any better, in the latest version the developer has added what can only be described as a 3-D graphics wonderland as a hidden bonus. Simply tap the "i" key, then "Help", then "About PCalc" and prepare to be amazed. You just have to try it; I don't want to spoil the surprise.

Sure, there are lots of calculators...

... But none like this! Pcalc has been around for a long, long time and is available on both iOS and macOS. However, the iOS version seems to be getting most of the love from the very talented author, and that's okay by me: I'm more likely to have an iOS device handy these days and I now find excuses to use this attractive and powerful app. I use it daily for various units conversions and general calculating.

I fell in love as soon as I discovered it had an RPN mode. Easily mastered, RPN is intuitive and eliminates any ambiguity over operator precedence in complex calculations. My nearly 40 year-old HP calculator still sits in a lonely drawer; I'd rather use Pcalc, now.

If you have an iPad Pro, the latest release has a delightful Easter egg that demonstrates the considerable computing and graphics power, while allowing the author to show off his programming chops. As an old-timer, I'm impressed!

Great calculator

Edit: I don't know when but at some point an option to choose from many app icons was added. It requires a tip, which is fine, except I do think the option to revert to the icon in place when you bought the app should be free.

This is the only calculator I use, and it's the best RPN calculator I've found. I really dislike the updated logo compared to the older simpler (matched iOS style better), and it looks completely out of place on my home screen now.
