RPN Calculator 48 is a polished RPN replacement for Apple's calculator app:
- Same scientific functionality as Apple's calculator app*
- Use swipe gestures to undo and redo operations!
- Starts quickly
- Large buttons
- Easy-to-read display
- 100 entry stack
- 6 memory buttons (A-F)
- 50+ levels of undo/redo
- Saves state on exit
The ergonomics (screen and keyboard layout) of RPN Calculator 48 were inspired by HP's outstanding 48-series calculator.
RPN Calculator 48 is made by the developer of tChess (the critically acclaimed iPhone chess game) and Learn Chess (the Apple Staff Favorite e-book).
* This app is not an HP 48 emulator.}
