How to block apps on an iPhone

Everything that blocks an app on an iPhone — including every blocker in the App Store — runs on the same foundation: Apple’s Screen Time and Family Controls. So the first useful question is not which app to buy. It is whether the free thing already on your phone does what you need, and if not, exactly which part of it fails.

Menu wording moves slightly between iOS versions; the paths below are current for iOS 26.

1. App Limits — a daily allowance

Settings → Screen Time → App Limits → Add Limit.

Choose whole categories (Social, Entertainment, Games) or tap into a category to pick individual apps, then set a daily time. The limit resets at midnight.

Two things worth knowing:

• Category limits cover apps you have not installed yet. Limit Social and the replacement app you download next month is already covered. This matters more than it sounds, because substitution is the normal failure mode.
• One minute is the shortest allowance. There is no zero. A one-minute limit is the closest Screen Time gets to blocking an app outright for a whole day.

The part everyone misses

By default, hitting a limit shows a screen offering One More Minute, Remind Me in 15 Minutes, or Ignore Limit For Today. That is not a block, it is a speed bump, and by the second week most people tap through it without reading it.

Open the limit you created and turn on Block at End of Limit. Then set a passcode — see below — or the toggle is just as easy to turn off as the limit was to ignore.

2. Downtime — a curfew

Settings → Screen Time → Downtime.

Downtime inverts the logic: instead of allowing everything and capping some of it, it blocks everything except what you list, for a scheduled window. You can set one schedule for every day or customise per day.

Settings → Screen Time → Always Allowed controls the exceptions. Phone cannot be removed, for obvious reasons. Keep this list short — every app on it is a hole in the curfew, and Messages on the list is enough to lose the evening.

Downtime is the right tool for a fixed problem hour. If your usage is a spike between ten and midnight, Downtime handles it more cleanly than any limit.

3. The Screen Time passcode — the step that decides everything

Settings → Screen Time → Lock Screen Time Settings.

Without this, every block above is one tap from off, and you will make that tap at precisely the moment you least want to. With it, changing a limit requires the code.

Use a code you do not use anywhere else. And consider the version that actually works for people who have already failed at this twice: have someone else set it and not tell you. It sounds extreme, and it is the difference between a block and a preference.

4. Restrictions — the loopholes

Blocking the app leaves three doors open. All three are closed in Settings → Screen Time → Content & Privacy Restrictions.

The website. Blocking TikTok does nothing to tiktok.com in Safari. Go to Content Restrictions → Web Content → Limit Adult Websites, then add the site under Never Allow. Do this at the same time as the app block or you have not blocked anything.

Reinstalling. Deleting an app and downloading it again takes fifteen seconds. Under App Store, Media, Web & Games → Installing Apps → Don’t Allow.

Deleting the blocker. The eleven-o’clock uninstall is the most common ending to all of this. Deleting Apps → Don’t Allow.

5. What does not block apps

Focus modes. A Focus silences notifications and can hide Home Screen pages. Useful against the reflex to check, useless against a deliberate open — the app still launches.

Deleting the app on its own. Fine for some people; a fifteen-second reinstall for others. Pair it with the install restriction or expect it back.

Hiding it in a folder or the App Library. Genuinely worth doing — it removes the unconscious open, where your thumb lands where the icon used to be — but it stops nothing you actually decide to do.

Deleting your account. A larger decision than this page covers, and a surprising number of people do it, fail to stay away, and end up here anyway.

When Screen Time is not enough

Two honest failure modes, both common:

You keep turning it off. The blocks work; the passcode is one you know. Either hand the code to someone else, or use a tool whose escape is genuinely expensive — a physical NFC tag, or a strict mode that cannot be ended mid-session. The comparison of iPhone app blockers sorts those by mechanism rather than by rank.

The block works and nothing replaces the time. This is the quieter failure. An hour removed and not filled gets reclaimed by a different app within a fortnight — usually a worse one, because you did not choose it. Things to do instead of scrolling is a list sized to that specific hour.

That second failure is the whole reason BookGate exists: the apps you nominate are shielded for the length of a reading session and come back when you close it, so the hour has somewhere to go rather than simply being taken away.
