The NCAA men's basketball tournament tips off Tuesday, providing days of excitement and hours of lost productivity. These apps can help you manage your brackets and office pools and keep tabs on March Madness wherever you are.

NCAA March Madness Live

(iOS, Android; free)

There are 67 NCAA Tournament games, and unless you're planning on doing nothing but staying home and firing up the big-screen TV over the next few weeks, this app will help you do some unimportant things, such as go to work or enjoy the spring weather outdoors. The app, from NCAA broadcast partner Turner Sports, will stream all the games, including those on CBS. For games shown on Turner's cable channels (TBS, TNT and truTV), you must log in with your paid-TV subscription credentials.

CBS Sports

(iOS, Android; free)

As usual, CBS will televise several tournament games, including the National Championship game on April 6. But the network is leaving the streaming to broadcast partner Turner Sports and its March Madness Live app. Still, the CBS Sports app offers a plethora of tournament news, scores and videos. There is also a Bracket Games feature, allowing you to set up pools and compete to win a trip to the 2016 NCAA Final Four in Houston.

If you don't want to create your own pool, you can join pools set up by fans and celebrities.

ESPN Tournament Challenge

(iOS, Android; free)

The players doing all the work won't get paid, but you might. This popular app from ESPN lets you use your knowledge of how the games will turn out to compete against others for prizes. Set up your brackets with your picks, and if you have the most correct predictions, you will win the grand prize of a $20,000 Best Buy gift card.

Swiss unmade?

"Swiss Made" has become a gauge of quality for watches, but Apple may sell as many timepieces as all of Switzerland, according to Elmar Mock, who helped create the popular Swiss-made Swatch in 1983. He said the Apple Watch may sell 30 million units annually. "I do expect an ice age coming toward us," Mock said. Switzerland's watch industry exported 28.6 million watches in 2014.-- Bloomberg News
