Boy my friends are being productive this year. First Rob with his book, now Jay with his first iPhone app that, uh, well let me just copy his description:
Yodel-Ay-Hee-Moo is the world’s first and only alpine cow timer… It is basically a countdown timer with a whole lot of fun and whimsy thrown in for good measure. What could you use it for? Many things I’m sure…..cooking, e-bay auctions, etc. Let your imagination be your guide. I absolutely love the “Moo-alarm”-the cow truly does sound alarmed…
I think that pretty much sez it all. 
Congrats for the launch! Go see his app at Runcible labs.
