Fantasy Monster Pro
Available for: iPhone, iPod, iPad
Go ahead, waste a whole lot of time and effort downloading and using NFL.com, Yahoo (YHOO) and ESPN fantasy football apps. It's cheap, if cumbersome and terribly inefficient. If you're serious about your multiple fantasy football teams, though, and can ill afford to forget if you benched Drew Brees in your Yahoo league but kept him in your NFL.com lineup, this is the only app you'll ever need. Fantasy Monster lets users do quick drag-and-drop edits and updates to all of your fantasy league teams in any sport, just in case your baseball team is still in the running and you're wondering if C.C. Sabathia will make his next start. The app also allows you to post to your league's message board and add, drop or trade players just as you would on your league's home page. Fantasy Monster Pro is definitely one of the costlier fantasy sports apps out there, but unless you're in a CBSSports (CBS) league, there's no substitute.
