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!

Release Notes

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.
