PCalc 4 is a brand new version of my veteran calculator application.
It is a fully featured scientific calculator for macOS with support for hexadecimal, octal and binary calculations, as well as an optional RPN mode, parentheses, programmable functions, and an extensive set of unit conversions.
- Switchable button layouts - choose from many different horizontal and vertical layouts to suit your needs. Includes all the layouts from the iPhone and iPad, as well as Mac-specific ones.
- A powerful Notification Center widget, for quick access to PCalc.
- Calculator themes - pick your look, all the way from minimalist to striking.
- An RPN mode with one button access to the stack, and optional multiple-line display.
- Editable user 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 main display.
- Smart searching of conversions, functions, and constants. Just search for "$ to £" for example.
- Stylish, consistent user interface.
- Support for Retina displays.
- Full AppleScript support.
- Multiple undo and redo.
- Modern 64-bit Cocoa application.
- Handoff of in-progress calculations between PCalc on iOS, macOS, and watchOS.

It costs $9.99 in the US, price varies in other countries. TLA Systems employs me and my wife Saskia full time, so paying for your copies of PCalc and DragThing really does make a difference to us!
