It has an interface that users of the HP calculator line will be completely at home with, including these features:
Scientific mode
Basic (large key) mode
20 Memories
Key click (haptic feedback)
Continouous memory
16-level stack
Front four stack elements displayed
Memories are not sacrificed to make room for program steps
RpnCalc has a sixteen-level stack to hold more data. The front four elements on the stack are visible at all times, making it much easier to keep track of where you are in your calculations.

Recently changed in this version

Version 2.19 Fixed bug when user enters too many digits

Version 2.21 changes the way the app remembers keyboard layout. There should be no visible change, but it will prevent bugs in the future when layouts change.

Version 2.20 died with a "class not found" error. Probably a compilation problem. Users who installed 2.20 should immediately install 2.21

    After fixing a data entry bug, this is now my default calc app. Fast, elegant and functional. Three thumbs up!

    Love this simple rpn calculator that can be in basic or scientific mode. Best of all, it's free for what you get.

    No need to dig out the HP calculator with this app. Works well too. With RPN, you can start anywhere to do the calculation.

    ...I prefer the HP48G app much more.
