Droid48 is a HP 48 calculator emulator for Android.

Quote:
- Better emulation loop, could fix the issue with the Settings panel closing the app
- New dynamic interface, better adapted to high resolution screens and tablets. The previous interface is available as an option (see "HP48 Bitmap Skin")
- HP48S emulation (you need to enable it in settings and restart the app)
- X86 and MIPS support
