That's amusing that SwissMicros branched off the work of Free42, a free (as in beer) reproduction of the HP-42S calculator. https://github.com/swissmicros/free

The author created and continues to support a build of Free42 for iOS, completely free. It's one of the most useful apps on my phone. My real 42S stays safe on a shelf.

- fmajid 5y agoYes, their innovation is in hardware, not software. I also keep my 1986 HP-15C safe and use a DM15L as my everyday calculator (a new meaning for EDC...). In fact I had a NIB HP-15C LE reissue (two, in fact, but one was stolen) and resold it when I got the DM15L (and a second one for redundancy), it's a much better calculator. I have Free42 for my iPhone and iPad but I tend to use the [official HP HP-15C emulator app](https://apps.apple.com/us/app/hp-15c-calculator/id503720774 https://apps.apple.com/us/app/hp-15c-calculator/id503720774) instead, or PCalc.
