Droid48


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)

Good app, but it crashes a lot. After about five user inputs, the app will just hang, and you have to restart it, and your calcs all over again.

Crash problem is back 3/2013 The new update crashed yesterday. Fast response from developer!!! Today this is still my favorite and most used app. Thank you Arnaud. 6/18/2025 update--Constantly crashing on Galaxy S6. Appears to be an Android 5.0 problem.

Good app. Equation writer not so much. On the Samsung S6 edge equation writer will freeze up and stop. Please fix, worked great on Samsung S4.

Memory Clears on rotate I love the app, but the stack clears when I lay down my Android. Turns out the "rotate screen" clears all the stack. Annoying to loose all my calculations from just laying my Android down. Can you fix it?

Best RPN calculator! Great app. Functions exactly like the HP 48 calculator, which is the best RPN calculator ever made. I am so excited to have it on my phone so now I can take it everywhere I go.
