Every other feed on your phone has at least the pretence of an ending — an inbox that empties, a list that runs out. TikTok's For You feed doesn't, on purpose. There's no bottom, no "you're caught up" marker, no natural place to stop that isn't just you deciding to stop. Searching for how to block it usually means the built-in screen-time tools have already been tried and quietly ignored, which isn't a willpower problem — it's what an interface with no stopping cue does to anyone.
What actually makes TikTok hard to close
Three things compound. The videos are short enough that "one more" is a real commitment of seconds, not minutes, which makes the decision to keep going feel almost too small to be worth resisting. The feed is aggressively personalised from very early in a session, so the fourth video is usually more relevant to you than the first one was — the algorithm gets better at holding your attention the longer you stay, not worse. And autoplay removes the one moment where you might have paused to decide whether to continue: the next video is already playing before you've finished deciding whether you liked the last one.
The built-in iPhone route, and where it gives way
iOS Screen Time can cap TikTok with an App Limit like any other app. Reach it and you get a one-minute warning, then a lock screen with a single "Ignore Limit for Today" button — no separate approval needed unless you set a Screen Time passcode yourself, in which case you're also the person who knows it. The mechanism is built for a parent restricting a device someone else can't unlock. On your own phone, the limit and the override both belong to you, which erases the entire point of having a limit in the first place.
The built-in Android route, and where it gives way
TikTok also ships its own screen-time nudge on top of whatever Android's Digital Wellbeing is doing — a periodic reminder that you've been on the app for a while, common on accounts flagged as belonging to a younger user. It's dismissed with a single tap, same as the reminder itself, and Digital Wellbeing's own App Timer for TikTok can be extended or switched off entirely from Settings at any time, by anyone holding the phone. Two separate reminder systems, both removable in one motion, aren't a barrier so much as a second thing to swipe past on the way back into the feed.
What changes when the toll is three questions
Mr. Grummel doesn't try to out-design an algorithm built by a much bigger team with much better data than a screen-time toggle has. It does something the feed itself can't route around: it puts three questions between your thumb and the app, before a single video has had the chance to autoplay. There's no "one more" to fall into, because nothing is playing yet. Answering costs a few minutes of actual thought, not a countdown you can wait out passively, and you keep whatever fact you land on either way.
A realistic day
Right now: you open TikTok meaning to check one thing, and forty minutes later you're not sure what the one thing even was. With the toll in place: the reach for TikTok hits three questions first, every time, with no bypass tap waiting on the other side of it. Some days you answer it and scroll anyway — that was never going to change, and it isn't supposed to. Other days, the few minutes of thinking are enough to notice you weren't actually looking for anything, and the phone goes back in your pocket instead.
