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).
Looks a lot like the original hp48 So great to use a smooth interface, with a large stack, and feel like at home with my dear hp48gx. Same behavior! (I was wondering if the app was using the original hp firmware in an emulator!).
The app doesn't have all the hp features (graphics, math modes etc.) but it has the essentials, nicely implemented.
