The app of the day rewards you for watching your favorite shows. It's called Viggle.

With the app, you "check-in" to shows and earn points as you watch TV. You can then trade those points for rewards like movie tickets, Starbucks giftcards, digital music, and more. Viggle even lets you share your "check-ins" on Facebook and Twitter. You can also earn extra points by playing games, watching videos, and taking quizzes in the app. Viggle is free to download and currently only available for the iPhone.
