Google IO starts in just six days, and the official app has finally hit the Android Market. It's a must-have if you're going to be at Moscone West next week (hey, that's us!), as it has a schedule of the keynotes and sessions, map of the venue (all three levels of it), sessions lists, bulletins, real-time tweets and more. Heck, even if you can't be in San Francisco next week, check it out just to follow along. Download links are after the break.
