Almost everyone who tries Screen Time App Limits has the same week. You set a cap on the apps that eat your evenings, you feel a small flush of control, and within a few days you're sailing past the limit without thinking. By the end of the week you've decided the feature doesn't work and you go looking for something stronger.
The feature does work. The blocking part is solid. What trips people up is the row of small, friendly buttons Apple puts between you and the block, and the fact that you hold the only key that opens it. Once you see the three gaps, you can shut them in about five minutes.
Gap one: the "One More Minute" button
When an App Limit hits, iOS shows a lock screen with a "One More Minute" option. Apple added it for a reasonable case: you're mid-sentence in an email or about to lose a level in a game, and you want a moment to finish cleanly before the app closes.
The trouble is what happens when you're not finishing anything. You tap "One More Minute," keep scrolling, and a minute later you tap it again. People learned long ago that you can force-quit the app, reopen it, and get a fresh grace period. The limit becomes a button you tap every sixty seconds instead of a wall.
There's no setting anywhere in iOS to delete that button on its own. But you can make the limit skip it. Go to Settings › Screen Time › App Limits, tap the limit, and turn on Block at End of Limit. Now when the time runs out the app just locks, with no one-minute extension offered.
Gap two: the "Ignore Limit" prompt
Block at End of Limit gets rid of the easy extension, but the lock screen still has a way through: a prompt that asks for your Screen Time passcode. Type the four digits and the app opens for the rest of the day.
This is the real leak. If you set the passcode yourself, you know it cold. So at the exact moment you're tired and want to keep scrolling, the only thing standing between you and the app is a code you can punch in with your eyes half closed. The block holds for about two seconds.
To even reach this point you need a Screen Time passcode set at all. Plenty of people never set one, which means the whole system can be switched off in a couple of taps. Set one under Settings › Screen Time › Lock Screen Time Settings. That closes the "just turn it off" exit. It does not, on its own, close the "I know the code" exit, which brings us to the part that actually matters.
Gap three: you know the passcode
None of the settings can fix the last gap. Every block on your phone ends with a passcode, and you're the person who typed that passcode in. Block at End of Limit, Downtime, content restrictions, all of it routes back to four digits sitting in your own memory.
This is why switching to a paid blocker rarely helps for long. Opal, Freedom, one sec, they all run into the same wall. You can end the session, because you set it up, so you do. The off switch moves to a nicer screen, but it stays in your hand.
If you want App Limits that genuinely hold, the fix follows straight from the problem: make the passcode something you don't know.
How to make App Limits actually stick
Do the two quick settings first, because they remove the lazy bypasses:
- Turn on Block at End of Limit for every limit that matters, so there's no "One More Minute" to tap.
- Set a Screen Time passcode and, while you're in there, set Downtime for the hours you keep slipping, like the last hour before bed.
Then deal with the part that everyone skips. The single most effective change is to stop being the one who knows the passcode. The simplest version costs nothing: ask a partner, a flatmate, or a friend to type a code into your phone that you never see. Now "Ignore Limit" leads nowhere, because there's no number in your head to enter. Getting past the limit means actually texting that person and asking, which is enough friction to stop most late-night impulse unlocks before they start.
If handing the code to someone feels awkward, or there's nobody you'd want holding it, WaitToUnlock does the same job without a person in the loop. It sets a random Screen Time passcode you never see, then only shows it to you after a wait of several hours. The limits you set stay set, because in the moment you want to override them, you simply can't.
The short version
Your App Limits aren't failing. They're handing you three off-ramps and you keep taking them. Switch on Block at End of Limit to kill the one-minute button, set a Screen Time passcode so the system can't just be flipped off, and then get that passcode out of your own head. Once you can't type it from memory, the limit you set at noon is still standing at midnight.
