Users can log movies, series, seasons, and episodes, add ratings and notes, save titles for later, and write reviews. As their library grows, they can explore viewing statistics such as hours watched, rewatches, streaks, and taste patterns.

The service also offers customizable profiles featuring favourites, curated lists, badges, review statistics, and recent activity. Social features let users connect with friends, compare tastes, and share recommendations. For planning what to watch, iWatched supports detailed guides that can arrange movies and shows in a chosen order, estimate marathon runtimes, and track progress for individual or shared viewing runs. Lists can be kept private, shared through unlisted links, or published publicly.

With pages for movies, series, and community-created lists, iWatched brings watch tracking, discovery, planning, and social sharing together in one place. Its goal is to help users remember what they have seen and showcase their entertainment interests.
