Some apps are especially useful to those of us of the geekier persuasion, particularly the conversion utilities. Many are revealed via Google search: simple javascript snippets on various web-sites scattered across the internet, or via any of a host of free app store utilities. In my geekier pursuits, I might rarely have to convert a HEX - RGB value for instance (to apply a particular color, etc.), or potentially do some binary math to calculate a proper subnet address. Actually pretty lightweight geek stuff, but hardcore coder types need to get at base conversions when programming in machine code. ProCode is written as a bare bones calculator focused for just that purpose. Oh, it will also help you calculate 2+2 (which I probably need more than the binary conversions anyway).
