One of the big ideas I got out of Extreme Programming was the concept of velocity.  That is, the idea that a team can do only so much work in a given time. As we end week number 3, I think I’ve proven empirically that my velocity is roughly 0.5 apps per week. That is, I’ve produced roughly 50% of an app for the past 3 weeks now.  I’m now planning that my current and future apps for app-a-week will take 2 weeks total development time.

This week’s app is a timer app, and, as I’ve said, it’s about half done.  I’ll release it to beta testers shortly, and should have it polished and ready to submit by next Friday. In the meantime, here are a few screen shots to whet your appetite.
