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.

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.
