Count It Out is a sample iPhone app (SDK version 3.0) that is intended to be a demonstration of Core Data as well as some UI controls that Apple doesn't give you out of the box (yet.)
The purpose of the app is to be a generic counting app that is useful for tracking the score of your baseball game (balls, strikes, outs, inning), the # of promo codes you have sent out for your latest and greatest iPhone app, or anything else you do in the day that requires keeping track of a running count or a countdown.
It will be up on the appstore soon as a free utility. In the meantime if you are interested in creating iPhone apps, learning CoreData, or finding some examples of settings UI tables with more complicated controls than those that come out of the box then check out this app (and if you want to contribute, shoot me a comment or message)
Thanks!
