ZapSeries is an easy to use library that allows you to track & share everything you've watched.
Follow your series, share your opinions about an episode with your friends.
The application does not provide video content and does not emulate the user interactions yet - (more features to come soon).
But you can still build your own library, tag episodes/series on the fly and get notified about new episodes to watch.
And you can go to the website: http://www.zapseries.com to set everything up.
