What Screen Time's app limit actually is
Set a daily limit on Facebook or Reddit, and the app goes gray with a lock screen once you hit it. That's the entire mechanism. The screen that appears has a button on it: Ignore Limit for one more minute, or for the rest of the day. Tap it, and the limit is gone until tomorrow.
That button isn't a bug. Apple's own documentation states plainly that Screen Time limits can be ignored once reached by default.[1] The restriction exists, and so does the way around it, built into the same screen.
Why Facebook and Reddit don't have smaller toggles
Most platforms in this library get a specific fix, hide Shorts, remove Reels, default to Following, because there's a specific recommendation surface doing the damage. Facebook's feed ranking and Reddit's front page don't split apart the same way into a named feature you can target individually. There's no Shorts shelf to hide. The whole feed is the thing.
That's why DoomOff treats both platforms with one switch each: block the site entirely, or leave it alone. Not because the toggles weren't built out, but because a partial fix doesn't correspond to anything real on either platform right now.
What actually holds a block
The difference between Screen Time's block and a Safari extension's block isn't strictness, it's where the decision happens. Screen Time asks you, in the moment, whether to keep the limit, which is the exact moment willpower is weakest. A site-level block through a Safari extension has no Ignore Limit button on the same screen. Getting past it means turning the extension off deliberately, in Settings, which is a different, slower decision than a single tap on a lock screen.
What this looks like in DoomOff
Facebook and Reddit both get the same option: block the site entirely, replacing it with a plain screen instead of the app. There's a break-glass unlock built in for the rare case you actually need in, fifteen minutes, once a day, so the block isn't absolute. It's just not one tap away, which turns out to be most of the difference.
