NBC has launched the official Windows Phone app for its hit music competition show The Voice. The app allows viewers of the show to, among other things, vote on their favorite contestants during the current season.

The Voice, in its US incarnation (the show actually originated in Holland) first started in 2011 and is now in its 8th season on NBC. This season's lineup of judges and coaches include Maroon 5's lead singer Adam Levine, country artist Blake Shelton, pop singer Christina Aguilera and R&B artist Pharrell Williams. Here's what Windows Phone users can expect when they access the app:

Keep track of your favorite artists through the season

Share your choices on Facebook & Twitter

Tweet the coaches right from the app

Make your own picks for battle winners and steals

Suggest songs you want the artists to perform

We're still waiting for the other big TV music competition in the US, American Idol, to launch a Windows Phone app.
