What is a YouTube RSS feed?
RSS is a simple, open format websites use to publish a list of their latest posts so other apps can read it — no login, no API key, no permission needed. Most people associate it with blogs and podcasts, but YouTube quietly kept the same system for every channel. It's just not something YouTube points to from its own app, since RSS feeds have no room for recommended videos, autoplay, or ads.
Every public YouTube channel has a feed URL built from its channel ID, and that feed lists new uploads in the order they were posted — nothing else. Focus Feed handles finding and reading that URL for you: you paste in a normal YouTube channel link, and the app takes care of the rest.
How it works
Using Focus Feed comes down to three steps: paste a channel link, get new uploads in order, and watch with nothing else attached — no recommendations, no autoplay.
