About this app

Emulator of the HP 48 scientific calculator, using RPN. Port of the X48 project (sources available on github). HP48's "grayscale mode" cannot be emulated.

Visit www.hpcalc.org for a large program collection.

Cool tip: tap the HP's LCD to show/hide a simpler numeric pad !

Very good emulation. The solver functions differently than my 48g/gx. Especially with the TMV function. One cannot move thru the data fields with the directional keys like the original. Some moves are allowed others are not and have to be made with the enter key. Also some of the loan length calculations seemed to miss calculate. The number display is not a extensive either. However this is one of the best emulations I have used.

i enjoy using this since i have been a long time hp48g user. i do miss the authentic button clicks. one flaw is that the random number generator isn't random. every time the app starts the function returns the same sequence of values. maybe base the seed in current time or something rather than returning sequential entries in an array (which is what it seems to be doing).

I have used the physical version of this calculater for 10+ years. Once I learned that there was a phone version I downloaded it because using the base calculater on my phone was confusing. I now have the calculater I use daily for work on my phone. The only downside of the app is that I haven't figured out how to turn of the vibration when buttons are pressed.
