How to study from YouTube without falling into the feed

This is the hardest blocking problem a student has, and it is worth saying why: the lecture and the trap are the same app. Physics Wallah, Unacademy, Khan Academy and half the best explanations of organic chemistry in existence are on YouTube, sitting one tap from a Shorts feed engineered by the same company to keep you there. Advice that says “block YouTube” is written by someone who does not study from it.

The order to do this in

1. Set the Shorts feed limit to zero (ten seconds, any platform).
2. Decide where your lectures will actually be watched — phone or laptop. Pick one.
3. On that device, narrow YouTube to the channels you study from.
4. On the other device, block YouTube outright during study hours.
5. Put the unlock somewhere that costs you a walk, or step four undoes itself in a week.

First: turn the Shorts feed limit to zero

In the YouTube app, tap You → Settings → Time management → Shorts feed limit, and set it to zero. When you hit the limit, YouTube shows a message you can dismiss or ignore, so this is a reminder rather than a lock — but it is free, it takes ten seconds, and it converts an automatic swipe into a decision. On an account a parent supervises it is stronger: the parent sets it from Family Center, and YouTube stops the Shorts feed for the rest of the day, resetting each morning.

Two other settings in the same area help. On the Home feed, tapping More above a grid of Shorts and choosing Show fewer Shorts thins them out (you can undo it from My Activity). And turning off your watch history removes video recommendations from Home altogether — which is the single biggest change you can make to what YouTube shows you when you open it to study.

On Android: an allowlist beats a blocklist

Android is the only phone platform where a blocker can see inside YouTube, because the accessibility service lets it tell the Shorts player apart from the watch page. That makes two useful things possible: blocking Shorts while leaving the rest of YouTube alone, and the stronger version — Study Mode in Spark, where you list the channels you study from and only those play. Everything else on YouTube, Shorts included, hits a block screen.

An allowlist is the right shape for this problem, and it is worth understanding why. A blocklist is a list of things you have already noticed pulling you in, which means it is always one new obsession behind. An allowlist is a list of what you actually came for — typically four or five channels for an exam — and it does not need updating when the algorithm finds a new way to interest you.

One practical detail when adding a channel: give its name as well as its @handle. A channel saved from a Short by handle alone can still play on the watch page, which is exactly the gap you were trying to close.

On a laptop: the cleanest answer on this page

If you can watch lectures on a computer, do. A browser lets an extension rewrite YouTube before you see it: Unhook, for example, is free on the Chrome Web Store and has a Hide YouTube Shorts switch, alongside options for recommendations, comments and the wall of videos at the end. Turn those on and YouTube becomes something close to a lecture player.

Then change how you arrive. Open your Subscriptions tab rather than Home, or bookmark the specific playlist you are working through, so the algorithm never gets a turn. The extension's limits are honest ones: it lives in one browser on one machine, and switching it off takes two clicks — which is fine, because on a laptop you are usually already working.

On iPhone: what is actually possible

Nothing on an iPhone can block Shorts and leave the rest of YouTube playing. Screen Time works on whole apps, and Spark on iPhone runs through the same framework, so it blocks YouTube or it does not. Any product promising Shorts-only blocking on an iPhone is describing something the platform does not currently allow.

So the split: lectures on a laptop with an extension, YouTube blocked on the phone during study hours, and the Shorts feed limit at zero for the times you do open it. It is less elegant than the Android answer, and it is the one that survives contact with a real revision week.

The part no setting fixes

Every method above is undone by the same thing: the off switch is on the device you are trying to resist. You will hit a block screen at 11 p.m. with a genuine reason — the lecture is for tomorrow's test — and the tool that lets you through in two taps will let you through in two taps every night after that.

This is what a physical key is for. With Spark, locking is one tap in the app or a schedule, and never needs the key once one is paired. Unlocking means getting up, walking to the key and holding the phone against it for about fifteen seconds (or tapping the NFC key). Put it in the next room and the 11 p.m. decision costs you a walk, which is usually enough to make you finish the chapter instead. The app is free, the key is a one-time purchase, and calls always get through.
