Marothon tracks TV and movies at the episode level, remembers exactly where you left off, and lines up what to watch next. Built for people who marathon. YOUR ROT LIST Everything you're watching on one screen, grouped by what to do next. Opening the app answers the only question that matters: what do I put on right now? EPISODE-LEVEL TRACKING Not "seasons watched" — the exact next episode, every time. Mark one off and the next slots in. Rewatches, half-finished seasons and shows you bailed on are all handled. NEVER MISS A DROP Get told when a new episode lands or a film you're waiting on hits streaming. Air times follow your timezone, not a server's. DISCOVER SOMETHING NEXT Browse by what's airing, what's new, what's leaving, and what people are actually watching — with cast, crew and trailers on every title. ROT TOGETHER Follow friends and see what they're watching. Compare your libraries side by side to find the shows you've both been meaning to start — and the ones you're hopelessly behind on. Accounts can be public or private, follow requests are yours to approve, and you can block or report anyone. Prefer to keep it to yourself? Turn the whole social side off in Settings. FREE No subscription, no ads, no paywalled episodes. Sign in with email, Google or Apple. This product uses the TMDB API but is not endorsed or certified by TMDB.
