Viggle, a TV check-in app that's already seen popularity on iOS, has just seen its first beta release for Android. Viggle, for those who don't know, allows users to check in to their favorite TV shows. The app accomplishes this by "listening" to audio and comparing the sounds it hears to a database, matching them with a certain television show.
What makes Viggle more interesting than many check-in apps is that users can earn tangible rewards. By checking in to TV shows, users earn points (specially featured shows offer more points), and those points can be redeemed for everything from sweepstakes entries to gift cards and electronic gizmos.
