Super cool! But I so rarely reach for the physical calculators I already have these days. Any recommendations on RPN calculators for Windows or Android? The one I've got on my phone right now has some little quirks that bug me.

RealCalc (Android) is the one I use all the time. Emu48 (Android, Windows) emulates HP48GX hardware and runs an actual HP48GX ROM image. NumWorks (Android, Windows, web) emulates a NumWorks graphing calculator - has some nice features, but not RPN.

I use one called 48sx, however, I've only ever used +-*/. Clicky physical buttons are much better of course. An accountant I worked with years ago had one with a printer, which meant she had a paper record and could verify that the entries were correct.

Which one do you have on your phone? Plus42 for Android has been mentioned. I like Droid 48 (also Android).

Hiper is pretty good (I paid for it, even) but the the lack of undo really winds me up.
