Contentualize is an app for rating movies, television series, books, and podcasts, and receiving recommendations based on those ratings. In its Discover section, users can like, dislike, or skip titles and save items to try later. After a user rates five titles in a day, the app generates a new batch of picks based on their ratings rather than current trends. The app also provides Circles, where users can discuss titles with others. Users can create a Circle for a group, such as a movie night or book club, post titles for consideration, and upvote options. Circles are public and can be found and joined by other users. Favoriting a title also lets users join its Circle and discuss it with people interested in the same title. Contentualize is available on iPhone, iPad, and Android. The app is free and supported by ads, with a Plus upgrade available to remove them. Its privacy information states that ratings are used to generate recommendations and app usage data is used to fix bugs. The advertising partner, Google, uses a device advertising ID to show ads; on iPhone, the app asks for permission first.
