Who Has It? — John Carstens

For "The X Factor" website, we focused on the show’s fundamental concept—defining, nurturing, and celebrating that innate star power that resides in all of us. On the homepage, choose from the ever-diminishing lineup of contestants, and your selection steps forward on the stage and belts out their signature riff. Each contestant has their own profile page, which contains clips, interviews, behind-the-scenes looks, and social buzz about them—including the occasional judge or celebrity comment.

And then there's the X Factor Rating, where we break down this trait into four subcategories: Voice, Look, Energy and Presence. Score the contestants on each of these measures to contribute to their overall rating, boost their confidence, and even influence the judges' assessments. Your dashboard tracks your favorite contestant’s “performance” between shows: changes in the community's X Factor Ratings, social commentary, and exclusive new footage. It also tracks your ability to predict winners and losers.

Use this second-screen app for viewing parties, where you and your friends dish on the contestants during the show—and compare your ratings and predictions.
