I can't believe the Massive Dev Chart is available on the itunes store. That's great news. Even has a built-in timer.

Worth the $6 to me. Probably the best $6 I'll spend on the app store, everything else I've bought has been great for a few minutes then eventually loses its novelty pretty quickly.

I've been using a tea timer on my Centro since my dollar store timer broke. Now I can use my iTouch.
