Rox play is certainly one of the best apps for series and movie addicts. With it you'll never forget which episode you stopped at. It basically serves for you to mark what you've seen and what you want to see, as well as those series you've given up on. It notifies you when new episodes are coming and offers curious information such as how much time you've spent watching series and how many episodes you've watched. In addition, it is possible to follow friends, so you know what they have seen, rate shows, comment and test your knowledge in quizzes of your favorite series.
