Stremio lets you stream things. Stremio can integrate with Trakt which keeps track of all the episodes/series you have watched. This addon uses your personal Trakt watched list to create custom catalog(s) of series with with only unwatched episodes visible.

These catalogs are a simple way to stay on top of when new episodes or seasons of your watched shows come out.

While Trakt's website can show you all of the 'in progress' shows you are watching using the following URL: https://trakt.tv/users/{$YOUR_USER}/progress/watched/activity/asc?hide_completed=true, this information is not exposed via it's API. The Up Next addon is an attempt to construct the same output using the lower level Trakt API's that are available and expose it as a Stremio addon.

The addon is not perfect and there are some edge cases that are not handled correctly. If you find a bug, please reach out on the StremioAddons Discord.

The metadata from Trakt is enriched with data from CineMeta to avoid hitting Trakt API rate limits. This mapping is done using the series IMDB id. If the a show in Trakt does not have an IMDB id associated with it, then it will not be displayed in the catalog.

Additionally, some series in Trakt do not have a 'last aired' episode associated with them which is used to determine if you have any unwatched episode. These series will not be displayed in the catalog.

Authorized Trakt apps have valid access tokens for around 3 months. Normally, applications would store and use a refresh tokens to automatically renew the access token before this expiry date. At this stage, the Up Next addon does not do this to avoid having to persist any data. This means that after 3 months, you will need to install the addon again through this page.

When enabled (disabled by default) the addon will fetch your Trakt Watchlist and add any series that are not already in your watched list to the catalogs. This is useful if you want to keep track of a series that has not started airing yet but want to be informed as soon as episodes air.

A user's Watchlist is a special Trakt list that will automatically have items removed once you start watching a series/season/episode (depending on what you added to the list).

This is relatively new functionality so please share feedback if you find it useful.
