How to Block YouTube on iPhone

If YouTube is what turns a ten-minute check into an hour, the failure is usually not that iPhone cannot block it. The failure is blocking only the app while Safari, short links, and the settings screen are still open.

First: the four ways a YouTube block fails

1. You blocked the app, not the website. YouTube still loads in Safari.
2. You blocked the main domain, not the route you actually open. m.youtube.com or youtu.be becomes the fallback.
3. Settings are unlocked. The same tired version of you can remove the block in seconds.
4. You never tested shared links. A YouTube link from Messages, Mail or Notes becomes the remembered escape route.

1. Block the YouTube app itself

For a single-app block, go to Settings → Screen Time → App Limits → Add Limit, open the Entertainment category, and choose YouTube. Set the limit to 1 minute so it behaves like a wall instead of a budget.

If your real problem is bedtime or work hours, Downtime is often better than App Limits because it blocks on a schedule instead of waiting for you to use up today's allowance first.

2. Block the website routes too

1. Open Settings → Screen Time → Content & Privacy Restrictions
2. Tap Content Restrictions → Web Content
3. Choose Limit Adult Websites
4. Add youtube.com, m.youtube.com, and youtu.be under Never Allow

This is the step most "block YouTube" guides skip. Blocking only the app is usually just moving the habit from the app icon to the browser tab or the short-link domain friends text you.

3. Lock Screen Time Settings

Use Lock Screen Time Settings and pick a passcode you do not know reflexively. Without this, the block is technically real and behaviorally useless.

4. Test the routes you actually use

• Open the YouTube app directly
• Open youtube.com in Safari
• Open a youtu.be link from Messages or Mail
• Try the route you usually relapse through late at night

If one path still works, your brain will keep it. Fix it now rather than counting on restraint later.

Best built-in setup by goal

Goal	Best built-in move
Kill YouTube after a minute	App Limit on YouTube
Block YouTube at night	Downtime + Always Allowed trimmed down
Stop both the app and browser route	App Limit or Downtime + Web Content restriction
You keep undoing it	Passcode + extra friction like sessions or streaks

What if the real problem is Shorts?

If long-form YouTube is useful but Shorts is the trap, the honest limitation is that iPhone cannot hide only the Shorts tab at system level. The practical workaround is still blocking all of YouTube during your danger hours, or using a narrower setup built around when the spiral starts.
