trakt.tv helps you keep a record of what TV shows and movies you are watching. Based on your favorites, trakt recommends additional shows and movies you'll enjoy!
There is an official API available which is already used by 3rd party developers to offer native Apps on Android and iOS.
Trakt.tv is a platform that does many things, but primarily keeps track of TV shows and movies you watch. It integrates with your media center or home theater PC to enable scrobbling, so everything is automatic. Some people like to check in from their phone, so we enable that too. Discover new shows and movies, follow people with similar tastes and voice your opinion.
The Trakt.tv API powers hundreds of apps on all the popular platforms like Kodi, Plex, MediaPortal, VLC, iOS, Android, Apple TV, Apple Watch, and more.

Pros
Cons
Con Not great support for non-english shows
Will only show content that has english titles. So even though the show you are looking for can have all the metadata with name, posters descriptions etc on "source" portals it will not appear on trakt unless it has english metadata to come with it.
