The ultimate app for the NCAA tournament is, aptly, from the NCAA. Watch all the games streaming live, listen to radio broadcasts, check scores and track your bracket with NCAA March Madness Live (Free, Universal). The only thing it won't do is make you snacks for the games. You'll have to make a purchase to watch all of the games, but it's a lot of basketball for $3.99.

One of the best parts of March Madness is the emergence of the underdogs -- seeing that 14-seed that has no business beating anyone sneak their way into the Sweet 16. Cheer for your favorite Cinderella stories with PlayUp (Free, iPhone). Hop into live chats and discussions with other fans to share your support, discuss big plays, or argue about which team has better jerseys.

Whether you're rooting for your alma mater or you've jumped the bandwagon of your personal pick to win it all, you'll want to display your true colors. Let everyone know who you've thrown your support behind with the University Wallpapers app (Free, Universal). Plaster on your background with the team colors of all your favorites -- or just the winners.

One of the longest-standing traditions of March Madness is filling out as many brackets as possible, followed by the tradition of never getting more than half of your picks right. Make filling out brackets even easier with PocketBracket ($0.99, iPhone). Create unlimited combinations with a few quick touches; because at least one of them has to be correct, right?

With so many games on and a lot overlapping in the opening rounds, it's hard to know what to watch. Thankfully, Thuuz (Free, iPhone) is here to let you know where to direct your eyes. Using algorithms to determine the excitement level of match-ups, the app notifies you when a game starts to heat up so you can flip to the right channel in time for a buzzer-beater.

The self-proclaimed "Worldwide Leader in Sports" would be remiss if it missed an opportunity to cover the biggest event in college basketball. ESPN is more than happy to provide excellent coverage of all the games with ESPN Bracket Bound 2012 (Free, iPhone). Flip through highlights, recaps, and analysis in both text and video form so you're always up on what's going down.

Sometimes you don't want all the noise of the analysis of the talking heads out there -- you just want to know what the score of the game is. Strip out all the babble and just get the updates you need from College Basketball Scoreboard (Free, iPhone). This app delivers the updates you want, and can be customized to your liking to display the teams you care about most.

With the field of 68 determined, it's time to fill out your bracket to determine who will be crowned champion. The only problem is you don't know the first thing about basketball. Don't worry, Office Pool Picker 2012 ($0.99, Universal) has your back. Just answer a few pop culture questions and the app takes care of the rest. It beats picking teams by who has the cooler mascot.

If you can't make it to any of the tournament games across the country -- or the title match in New Orleans -- but still want the atmosphere of being at the game, grab Sounds of Madness (Free, iPhone). The app comes loaded with some of the big calls from announcers and chants from the crowd, plus you're sure to be a hit at any watching party with the air horn feature.

The March Madness tournament has a long history of great matches, emerging stars, and some of the most memorable events in sports. Relive them all and quiz your friends -- or strangers if you really want -- with iQ College Basketball Trivia ($0.99, iPhone). Unlock bonuses, land achievements, and compete against the global scoreboard. Try to beat the shot clock with your answers.
