It’s late, you open YouTube for one clip, and autoplay quietly loads the next, and the next. Deadbolt ends the rabbit hole before it starts — bolt YouTube shut, or schedule it to lock every night on its own.
Option 1 — Apple’s built-in Screen Time
Free, already on your iPhone, and fine for a soft limit. Here’s the fastest path:
Open Settings → Screen Time.
Tap App Limits → Add Limit.
Choose Entertainment or search for YouTube, then tap Next.
Set a daily limit and tap Add.
The catch: Screen Time limits are one tap to ignore — "Ignore Limit → Ignore for Today" — so they rarely hold once the craving hits. That’s the whole reason dedicated blockers exist.
Option 2 — Deadbolt (the one that holds)
When "ignore for today" is too easy, bolt YouTube shut for real:
Open Deadbolt and tap Edit on the apps card.
Select YouTube (add it to a "Deep Work" blocklist for one-tap arming).
Pick a duration and tap Bolt it — no more "one more video."
Add a daily schedule for late nights so YouTube locks itself at bedtime.
Enable Strict Mode so autoplay can’t lure you back mid-session.

YouTube blocking — FAQ
How do I stop watching YouTube Shorts and autoplay?
Shorts and autoplay are designed to chain videos together. Blocking the YouTube app during your focus or wind-down hours removes the rabbit hole entirely — Deadbolt bolts it shut for a set time or on a schedule.
Can I block YouTube only at night?
Yes. A recurring overnight schedule (e.g. 11pm–7am) locks YouTube every night automatically, so "one more video" at midnight isn’t an option.
Can I block YouTube during study sessions?
Create a strict daily schedule for your study block, or bolt YouTube manually before you start. In Strict Mode you can’t quit early without a cooldown or a walk.
Does it block the YouTube website?
Deadbolt blocks the YouTube app through Apple’s Screen Time. For web access, add a Safari website limit in Screen Time during the same window.
Is it free?
Yes — bolt YouTube for free (up to 15 minutes, twice a day). Longer sessions, Strict Mode, daily schedules and unlimited blocklists come with Deadbolt Pro ($4.99/mo or $29.99/yr).
