For more info on the non-technical side of Callisto, visit its own website at http://callisto-app.com
First let me preface by saying that Callisto is the very first app I've ever made, period, for any mobile device. With that in mind, there will undoubtedly be things that you see that are done stupidly, and sometimes I see them too. I wrote Callisto after one summer class in Mobile Development, during which we mostly just modified existing code. So Callisto was as much a learning experience for me as it was a project.
