RpnCalc is the best and most popular RPN calculator on the Android Market.

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.

See http://www.efalk.org/RpnCalc/ for manual

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

    Should adopt "long press to activate shift-function" like some competitors do. STO and RCL should list out memory registers.

    Very professionally made with a familiar interface and the glories of reverse Polish notation. The only thing I miss is a programming language. But it's a free app so 5 stars out of 5.

    Great application I use it because it is easier than the ones that have the equal signs.

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

    So much like my 35s I've started leaving the hp at my desk and using this app when in the field.
