The official UConn app is pretty good - it's run by CBS Sports.
Schedules, rosters, news, etc., etc.
I would hold off on the in-app purchase just yet - that being live audio feeds. There was some trouble with an early football game - chatted with someone from UConn about it at that time and they were taking steps to make it better. I want to see how it works during a hoop game before I recommend that aspect of it.
