What does your workflow look like? After two weeks, what have you actually made to aid you in making the app, I'm talking about models, diagrams, mockups, pseudocode etc. You're building apps in such a short timeframe. I'm currently building my first serious app for a client, and I'm already a few months in, and I'm far from done, it's not an unreasonably complex app either. Also, if you don't mind, may I take a look at your mini-framework? I'd love to see it.
