About

SlySeries

Read full description

SlySeries is a simple, no-nonsense show tracker: what you're watching, what's coming up, and what the community thinks of it. TRACK YOUR SHOWS Add a show, check off episodes as you go โ€” SlySeries remembers everything and syncs your library across your devices via iCloud. Episodes check off in order, so there's no need to scroll through a whole season by hand. NEVER MISS A RELEASE The Agenda gathers new seasons of shows you follow, and surfaces catalog releases from your subscribed platforms (Netflix, Disney+, Canal+, Paramount+, HBO Max, Prime Video). Turn on notifications to get alerted the day an episode drops. THREE RATINGS, ONE PAGE Every show shows its BetaSeries rating, its TVmaze rating, and the SlySeries community rating โ€” built from votes across every SlySeries user, independent of the other two sources. DISCOVER WHAT'S WORTH WATCHING The app's Top 10 ranks the highest-rated shows across the whole SlySeries community โ€” including ones you haven't added yet. YOUR DATA, YOUR ICLOUD Your library (tracked shows, watched episodes, favorites) stays in your own private iCloud account โ€” SlySeries never has access to it. No ads, no third-party tracking. Data provided by betaseries.com and tvmaze.com.
