I follow a lot of TV shows, but I do it a bit more systematically than just sitting down to see what's on. As such the concept of a TV guide that tells me what is on is rather useless, as I need something that tells me when something is on instead. On Android, an app I've used for ages now is helping me do that: TV Show Favs.
TV Show Favs is basically an all in one app for keeping track of what's on TV and when it airs. It has a lot of features like the ability to keep track of which episodes you've seen for a show, share your favorite shows on social networks, syncing between devices, and things like that. I personally use it to list all my favorite shows and display upcoming episodes for those as a widget. The app offers widgets for both phones and tablets, and the widgets also look better than many widgets out there. I've used a lot of methods for keeping track of TV schedules over the years, but I have to say that this one is my favorite so far.
The app comes in two versions, one ad supported free version and a $3 premiun version. There's a 14 day free trial for the premium version so you can try out the full experience, and if you're like me, $3 is well worth what this app offers.
