How to block apps on iPhone so the block actually holds

Screen Time limits are easy to skip. The three ways to block apps on iPhone, why the built in one fails, what a blocker can and cannot do under Apple's rules, and how to make unlocking cost something.

Updated 2026-09-16

Every iPhone has a blocker built in, and almost nobody’s holds. The problem was never the block. It is the button that says Ignore Limit.

Option 1: Screen Time, built in

Settings, Screen Time, App Limits. Pick the apps, set a daily allowance, done. Downtime does the same on a schedule. It works until the limit hits, when iOS offers Remind me in 15 minutes and Ignore limit for today. You will press one of them. Everyone does.

The fix inside Screen Time is a Screen Time passcode that someone else holds, so the skip needs a code you do not have. That works for a child. For an adult it means asking your partner every time.

Option 2: Delete the app

Underrated. Instagram in Safari is worse than the app, which is the point. Costs nothing, holds for as long as you can resist reinstalling, which for most people is about four days.

Option 3: A blocker that makes unlocking cost something

Third party blockers use Apple’s Screen Time and Family Controls frameworks. When an app is blocked, iOS puts a shield over it at the system level. Force quitting the blocker does not remove the shield. What the blocker controls is the rule for taking the shield off, and that is where they differ.

Sixteen’s rule is that your body pays:

  • At night, apps lock on the sleep schedule you set and stay locked until morning. Your recovery score can hold them a little longer after a bad night.
  • During the day, three slow breaths open a ten minute window, then the shield comes back on its own. A walk, a workout, a logged meal or a finished task pays minutes into a bank you spend on the apps you chose.
  • In a focus block, everything distracting is quiet until the block ends.

That is enough friction to stop the reflex, and not so much that you delete the blocker on day three.

What no blocker can do on iPhone

Apple’s rules mean a blocker cannot read what you do inside blocked apps, cannot stop you deleting the blocker, and cannot block a website without you picking it first. Anyone promising more than that is not using Apple’s framework. We say so on the screen time page too.

The order that works

  1. Delete the two apps you are most ashamed of.
  2. Block the rest on a bedtime schedule, because night is where the hours go.
  3. Make daytime unlocking cost something small and physical.
  4. Look at the weekly number once a week, not the daily one every hour.

Questions people ask

Can you completely block an app on an iPhone?
Yes, three ways. Screen Time's App Limits and Downtime, which you can skip with a tap. A Screen Time passcode held by someone else. Or a third party blocker built on Apple's Screen Time API, which shows a shield over the app and only opens it under the rules you set. Deleting the app is the fourth, and the one people forget.
Do app blockers actually work?
The blocking works: Apple's Screen Time API shields the app at the system level and the blocker cannot be bypassed by force quitting. What fails is the unlock. If the way out is a tap, you will tap. Blockers that make unlocking cost something, time, a task, a breath, or a walk, are the ones people keep.
How do I permanently block certain apps?
Set a schedule that covers the hours that matter and remove the easy exit. In Sixteen, apps lock on your sleep schedule and stay locked until the morning; during the day a three breath pause opens a ten minute window and then the shield comes back on its own.
Can a blocker see what I do in the blocked apps?
Not through Apple's Screen Time API. Apple designs it so the blocker never receives which apps you use or for how long. Sixteen cannot see the list of apps you chose or your usage; only your phone can.
Is there a free app blocker for iPhone?
Apple's Screen Time is free and built in. Several third party blockers have free tiers. Sixteen is not free: $99 once or $19.99 a month, because the blocker is one part of a health app that scores your sleep and recovery and uses them to decide when apps open.
