I wrote an iPhone calculator app

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&rsquo;ve been plugging away at it for 3 months now as one of my many side projects. &#xA; I&rsquo;m ready to call it a usable version 1.0. I&rsquo;m sure there are bugs, but I&rsquo;ll work those out as I use it more.
