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 !

- Freezing should occurs less, I'm still working on the issue
- Minimal screen is accessible again with a single touch !
- Menu is then accessible on the right side of the LCD screen ("3 dots" appearing on top right, at each app launch)

Excellent, incroyable, mais il me semble que le dessin des touches est encore plus proche de la réalité dans l'application iphone m48; p. ex, la lettre x est mal dessinée à droite... 1) Et encore: l'heure normale (d'hiver) (UT+1), revient tj à UT+0. 2) Impossible d'obtenir le son, par exemple 5/0, lorsqu'on coche l'option sound. 3) Pour l'éteindre, il faut faire "2nd"ON, puis ON (le sablier tourne tj), puis encore ON !

There is a bug when using an option from the menu (say FFT), going then back to the menu using green arrow-NXT, then picking another menu (say CONS) and then trying ot go back to menu. It goes back to previous choice

This is a great app! Regarding the request for the Casio FX-602P, there is one! Just look for it.

Does EVERYTHING!! Unfortunately, it doesn't work like the TI-83/89, and I cant figure out how to use it. Steep learning curve, but a great replacement for graphing calculators. I prefer Andy-83, but still a great app!

HP48G I love my three HP48G calculators, and when I don't have one of the three with me, this app is fantastic on my phone and tablet. RPN is the best.

Simply the best calc app! Great emulator for one of the best calculators made during my college years ...HP48g. Thank you so much. Im really thrilled to be able to carry this app around in my cell phone. Update: Freezes up constantly on Nexus 5. Hopefully the developer will find a solution for this. At least for replacement there's also the droid48sx app that resembles this app a lot and is very stable on most Android versions.

HP RPN cals were the best I still think the RPN system, is the best way to do cals. I had one at uni and used it extensively until it was stolen (if you read this you can still give it back, please). This app is almost like the real thing, the only thing it is missing is the feeling of a real HP keyboard.

Love this app! Bug fix please! I have been using this app for a long time. Replaces my 48gx completely. When I got my nexus 5 a couple months back, it started freezing up randomly. It happens right after I touch a button, even just adding two numbers, but it happens almost every time I use it. Maybe every tenth calculation. Force close and restart and it works again for a bit. Both on KitKat and lollipop.
