Keys are much more responsive than Emu48, but this emulator fails to save the state of the machine. A Google search indicates this may have been intentional, requiring the paid version in order to save the state of the emulator. Fair enough, but I see no play store option for a paid version... super annoying to not be able to save my custom unit conversions. All I really hold to be the single feature of my HP48GX is its unit conversion stuff, all else I do on a PC now....

This is perhaps the app I use more than any other. While it's an emulation and I probably won't be writing 80 lines of code for matrix decompositions.... I've still used it for a quick regression now and again. This is amazing, used it since year 1... I do hope there are plans to keep this going for another 20 years. I plan to still NEED RPN for 20 more years. Thanks again for this app. And yes... I would not mind keeping the stack my phone's memory registers... Even through reboot. Someday?

It's wonderful. I've found nothing to dislike. It's just like my old HP48 calculator from back in the day. I cut my teeth as an engineer using RPN (Reverse Polish Notation) and it's hard to go back. RPN sadly has gone out of fashion. It's faster, especially if a formula has lots of parentheses. One issue: I can't seem to keep my number format mode set to Engineering. Always back to Standard when I reopen the app. Help with that would be appreciated.
