RPN Calculator 48 is a polished RPN replacement for Apples calculator app:

- Starts quickly
- Large buttons
- Easy-to-read display
- 100 entry stack

The ergonomics (screen and keyboard layout) of RPN Calculator 48 were inspired by HPs 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).
