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.
