User reviews of Free42
I have been a HP-42s user since 1991. I am very pleased with the Free42 emulator. I have used the versions for Palm OS, Windows, and now Android.

Excellent Best HP emulation that I have found. Don't need programming function, so a simpler model would be easier to use.

Using HP calculators since the first HP35 I bought back in 1974. This emulator is as good as any of the HP hardware I've owned. Love it and use it everyday!
