Even if the firmware could be updated to support RPN, the keyboard doesn't look very usable for RPN entry. The HP Prime might be a better choice if you want RPN, or the HP 35s.

About RPN...

Or, alas, just RPN Calculator on Android, which besides not having real keys is otherwise close to perfect.

If NumWorks did propose an RPN version (with associated keys) I would buy it immediately indeed...

There are at least two apps in the Play Store by that name, and a boatload of apps with similar names. I'd like to see if I can get used to RPN; which app would you recommend?

I have "RpnCalc" by Edward Falk. It's not like having my old HP 41C back, but it is a good emulation of the RPN calculator experience. I'd recommend it.

One alternative is Free42, which emulates an HP-42. Then there's an app version of the HP Prime, which was mentioned earlier.
