ash_borer: (also comes with a paid version) is my favourite movie info app. Has ratings from IMDB, Flixster, Rotten Tomatoes, and Metacritic. The layout is great, you can create your own lists (to keep track of what you want to watch, for example).
This is movies and TV guide, this app is not for watching full movies and episodes. Organise and discover movies and TV shows. Get full information on movies and shows from multiple sources such as IMDb, Rotten Tomatoes, Metacritic, Flixster and more.
Manage trakt.tv or themovidb.org accounts. Add and modify watchlists and episode progress.
Watch Youtube trailers.
Search local cinema with Foursquare.
Search by genres, years, actors and studios.
DVD and theater release notifications.
