PCalc is ideal for scientists, engineers, students, programmers, or indeed anybody looking for a feature-rich calculator for the iPad, iPhone, or Apple Watch.
It includes an extensive set of unit conversions, a paper tape, an optional RPN mode, engineering and scientific notation, as well as support for hexadecimal, octal and binary calculations.
It's PCalc at your fingertips!
Based on the popular calculator for the Macintosh, PCalc has been redesigned from the ground up to give the best handheld experience.
- Switchable button layouts - choose from many different horizontal and vertical layouts to suit your needs. Plus a full editor, so you can create your own and share them with others.
- Apple Watch support - a full calculator on your wrist, with support for RPN. Also includes a tip calculator.
- Support for splitscreen multitasking, both in slide-over mode and full split view.
- A Notification Center widget for quick access - tap the display to switch to the main app, mid-calculation.
- Calculator themes - pick your look, all the way from minimalist to striking.
- An optional RPN mode with one button access to the stack and optional multiple-line display.
- Editable unit conversions, functions, and constants which are synced automatically across multiple devices.
- Hexadecimal, octal and binary modes, complete with a variety of bitwise operators.
- A simulated paper tape to keep track of your calculations with a "ticker tape" mode under the display.
- Multiple undo and redo. Just flick the LCD to the right and left to reveal the past and future.
- Stylish, consistent user interface.
- Universal build supports both iPhone, iPad, and Apple Watch in one.
- Handoff of in-progress calculations between PCalc on iOS, watchOS, and macOS.
- 3D Touch support, including fully customizable icon menu shortcuts.
- Full support for iOS 11 and iPhone X.
- Even a (pretty silly) AR calculator mode!

You can buy PCalc on the App Store by clicking the button below:
It costs $9.99 in the US, price varies in other countries. PCalc is a universal app - one purchase will work on iPad, iPhone, and Apple Watch. PCalc requires iOS 8 or later. The Apple Watch app requires watchOS 2 or later.
In the continuing absence of demos or trial periods in the App Store, the idea behind PCalc Lite is to provide something useful and free that's better than the Apple calculator, but which will also drive interest in the full version. PCalc Lite is a great calculator, but PCalc is even better!
You can now purchase all the extra features from the full version of PCalc from inside PCalc Lite. Buy them individually, or buy everything.
