Bracket Busting Apps—Guide to March Madness on your iPhone, iPod, iPad, and Android.

iOS (Apple iPhone, iPod, iPad):

March Madness On Demand (iPad, iPhone) - Easily the number one app that needs to be installed for anyone interested in following the tournament on their iOS device. Why? Two words: live streaming. You'll get all of the games, on Wi-Fi or 3G, for free and the quality is solid.  We'll see if the app can survive with all of the attention it's going to get during this first weekend.  A full review with screenshots is available here.

ESPN Bracket Bound (iPhone/iPad) - For those looking to follow their brackets and check out the leaderboards, chances are you are likely on either ESPN or Yahoo.  Fortunately, both have their own free app for you. ESPN presents a universal app, which is great for iPhone and iPod Touch users, but those with an iPad will have to deal with the small screen (see photos). Once logged in, you'll be able to not only see all entries and leagues, but you can create new and edit existing entries all through the app. And when the tourney is rolling, you'll be able to see leaderboards both for any groups you've joined as well as the overall one (fun for watching as the number of perfect brackets decrease daily.)    

 Yahoo Tourney '11 (iPad, iPhone) - This free app offers a similar experience for their bracket game - Yahoo Tournament Pick'em. Use the app to pick your teams, track your brackets and compare your standing to others in your group. Similar to the developer's Sportacular offering, Yahoo Tourney '11 offers push notifications for several options including game start, end, and even when there's a close game.
