(CBS News) March Madness is here! Sixty-four National Collegiate Athletic Association (NCAA) teams will duke it out to win the championship. Here are some websites and apps that will keep you on your game as we countdown to the final four.
Surprisingly, there aren't many apps created for the NCAA championships. CBS Sports has the most used app, with over 60,000 active users. The app lets you create brackets, pick your final four and check scores.
There is also an app called 2012 March Madness Office Pools with 900 active users. The app strips down the brackets to just two teams. Make your picks and wait it out.
NCAA March Madness Live (Android, iOS) - The official NCAA app lets you check game schedules, fill out brackets and get game alerts. For an extra $3.99, you can also stream games on mobile devices.
Thuuz (Android, iOS) - Thuuz actually tracks all of the major sports leagues and games - not just the NCAA. Once you pick your teams, the app will send alerts and game schedules. One cool feature is the use of location-based technology to find a sports bar in the area to watch games.
PocketBracket: Men's College Basketball (Android, iOS) - PocketBracket is a pretty slick looking app. It has a touch interface that makes it super easy to pick teams.
SportsCaster (Android, iOS) - SportsCaster is the best way to keep up with a game if you can't actually watch it. The app lets you check scores and read real-time updates from teams, analysts and players via their Twitter accounts.
All of the major networks, like ESPN, CBS and NBC have brackets available. Fill in your teams ASAP because time is running out!
