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 !

Ratings and reviews

It's just like a real hp48. It's fast, complete, the keys work well. Every function I tried worked just like the actual calculator. I'm keeping it. Thanks for the great program! Update! For about a year I've used this app all the time. It is in my top 5 most trouble free apps. It doesn't need access to anything. The author has no ulterior motives. It's actually 'free'!

It works just like an hp48 for everything I've tried. (I haven't tried running other software on it). One requested feature would be some sort of undo button. Since its a bit smaller on my phone, and I can't feel the keys on a touch screen, it's easy to hit the wrong button.

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).

Trying some things to help with the crashes/freezes
