Sequel gathers a media backlog into a single library. Films, television, books, and games can be organized into collections, with progress records to distinguish something you plan to start from something already underway. The official listing includes iCloud syncing in the free tier.
Free features include unlimited library items and a limited number of collections. Sequel+ adds tools such as Trakt integration, watch availability, release reminders, notes, and additional collection options. Those additions are most relevant when maintaining a larger library or following upcoming releases.
Sequel is a tracker and discovery tool rather than a subscription to the media it lists. Streaming availability and release information can change, so confirm availability with the relevant provider. This overview is based on official descriptions; it does not claim testing of Trakt synchronization or catalog completeness.
