When you tap the screen, Viggle's software for iPhones and iPads listens to what's on, recognizes what you're watching and gives you credit at roughly two points per minute. It even works for shows you've saved on a digital video recorder. Rack up 7,500 points, and you'll be rewarded with a $5 gift card from retailers such as Burger King, Starbucks, Apple's iTunes, Best Buy and CVS, which you can redeem directly from your device.
