The America's Got Talent judges want YOU to vote! With such power at your fingertips — as viewers now are in charge of voting — the audience is now the most important judge of the NBC talent competition show.

As the America's Got Talent live shows continue, the judges Simon Cowell, Mel B, Howie Mandel, Heidi Klum, and the show's host Tyra Banks are urging fans of the show to vote using the AGT app or by going online.

Available by Google Play and the Apple store, the AGT app allows viewers to vote as the show proceeds. You can even customize the buzzer sounds with each of the judge's voices! Are you a Simon fan? Maybe you like Heidi's judging style best… This customizable feature is combined with access to real-time results of voters, red, green, and golden buzzers during performances, a Facebook Share button, and the ability to tweet Tyra and the judges directly from the app.

For viewers who aren't interested in downloading the AGT app, voting is still available online through NBC's website. Voting begins tonight, as soon as the live show starts.
