The rundown

A tracker that keeps up with your backlog

No spreadsheets, no “wait, which episode was I on?” Marothon does the bookkeeping so you can get back to the couch.

Your Rot List

Your whole watch life on one screen

The Rot List groups everything by what you should do next — so opening the app answers the only question that matters: what do I put on right now?

  • Up Next and Watching surface shows you’re mid-marathon on.
  • Lagging Behind nudges the ones piling up new episodes.
  • Watch Later parks the maybes without cluttering the queue.
Episode-level tracking

It knows the exact next episode

Mark an episode watched and Marothon advances you automatically. Across every show you’re juggling, Up Next always points at the right S-E — no counting, no guessing.

  • Season-by-season progress for TV, plus movie watchlists.
  • Rate as you go and build a history you can actually scroll back through.
Upcoming & alerts

Never miss a drop

See what’s on the way with countdowns to new episodes and releases — sorted by streaming vs. in theaters, right on your Rot List. Turn on push alerts and a new episode is never more than a glance away.

  • Air-date countdowns for the shows and movies you follow.
  • Push notifications the day a new episode drops — opt in from Settings.
