Over Christmas, I spent a lot of time with my beloved (and quirky) HP-16C. I decided I wanted to take it everywhere, but doing a phone calculator app seemed daunting. I've been plugging away at it for 3 months now as one of my many side projects.

I'm ready to call it a usable version 1.0. I'm sure there are bugs, but I'll work those out as I use it more.

@mrdoornbos Very cool. I have the SwissMicros replica but I can’t stand the texture on the back. I use it constantly when I’m doing assembly and am continuously reminded how much I would prefer a real one.
@tpolecat I happen to have both. The original has gotten expensive to find these days.
