48sx, a vintage RPN calculator v13.1

48sx : The HP48 sx emulator!

HP48sx is a vintage RPN calculator. I have used this calculator 30 years ago and I truly appreciate its functionality. Now, I can conveniently carry it in my pocket every day thanks to the HP48sx emulator for Android, recently launched on the Play Store. The bundled ROM is available for free for non-commercial purposes and is ad-free, making it a desirable choice for calculator enthusiasts.
