The mobile half of Catch-Up Scheduler: this page checks your channels for new uploads and plays them back to back. Everything lives in your phone's own local storage — no account, no server, nothing synced anywhere.
Works right away with a small built-in example channel — no setup required. It checks for new uploads the moment you open it and plays whatever's unwatched, newest first.
In Safari: Share → Add to Home Screen, so it opens full-screen like an app.
One tiny Shortcut — it just opens this page, nothing more. Point a Personal Automation at your usual free time and it'll prompt you to catch up.
Build a list of your own, download it, then load it from inside the app (footer link at the bottom of the player).
