A new feature in the Google app will make it easier for you to keep track of the shows and movies you've watched and want to watch. Some users on Reddit spotted a new card underneath the trailer tab with buttons "Watched It?" with a checkmark and "Watchlist" with a bookmark icon. Not all users seem to have access to this feature yet. But it's accessible through the Google app for iOS and Android or on the web.
If you tap on the Watched It button, this will then change to Watched. Meanwhile, if you select the Watchlist button, the movie or show will be added to Google's bookmark list, which you can access through this link (google.com/save). There you will see a new Watchlist collection with cover art featuring the movies and shows. One other way to see your list is to type "My watchlist" into the Google search bar, which shows your complete list as well as film release dates. There doesn't seem to be a way to see what you've watched, unfortunately.
