What's the best iOS app for managing multiple fantasy sports teams and leagues all in one wonderfully organized place?

Well, after trying a few different options, I've settled on the ESPN Fantasy Sports app. It's like having a card catalog for all my fantasy leagues right in my pocket! I’m managing three different leagues this year – football, of course, and I've gotten quite into baseball and basketball as well. The categorization system is brilliant; I can easily switch between leagues and teams, check scores, and even manage my rosters. I figured out three new features this week alone! Who knew my phone could do this? It's made keeping up with everything so much easier. The interface is also wonderfully organized, which, as a former librarian, I deeply appreciate. Quite impressive, actually, how they’ve managed to put so much information at my fingertips.
