The HBO Go isn’t just your everyday app. Sure it’s all free to download but don’t let that fool you, it needs an HBO subscription through your cable TV services. But what makes this app valuable is its huge database. Missed the last season of the Game of Thrones? This is probably where you should look. HBO original shows like Band of Brothers, The Sopranos, True Blood and Entourage all feature here along with a giant collection of movies.
