An interesting app for fans of films and series: Trakt.
Trakt helps you keep track of the films and series you have watched. The makers have built up a database for this purpose with a large collection of films and series. You look up the series or film and then indicate that you have watched it. You can also assign a grade so that you can sort the series at a later time. It is also possible to create a viewing list in which you list the productions that you would like to watch.
Do you have no inspiration, but would you like to watch television? Trakt also offers an overview with suggestions. You can also rely on the findings of fellow users: based on what others have seen (and any comments they have given on productions), you can make new selections.
You can use the app for free, but there is also a paid version available. This allows you to request statistics about your viewing behavior, among other things. You see how many productions you have watched and how many hours you have spent on them. The paid version also has more filters, which should make it easy to search for specific productions. If you do not need the app, you can also use the associated website on which the app is based. You can find this on Trakt.tv.
