My First iPhone App in the Next 7 Days?

This week I'm doing some rather tedious non-programming tasks on my main product, Poker Copilot. So I need something else to exercise my mind. The goal I've set: my first iPhone app. I'll aim for daily progress reports over the next seven days.

I know some Objective-C and Cocoa; I'm well-acquainted with many iPhone apps (Angry Birds, cough, cough); I have an idea for a non-novel, simple iPhone app. I think I can do this.
