The new fall shows are on TV and it can get a little overwhelming to keep track of what you've already watched. SeriesGuide Show Manager makes a list of everything you've seen. You start by adding your favorite shows into the app, as you watch and episode, you can check mark it. SeriesGuide will show you which shows you need to watch, plus give you a rundown of each episode. You can also share your favorite episodes with your friends.
SeriesGuide is free to download. Currently, it is only available on Android devices.
