There are six different ways to block an app on an iPhone, and all of them are already on your phone. Here is how each one works, in the order most people need them — and the one thing they all have in common, which decides whether the block survives past Tuesday.
Everything below is built into iOS. Nothing here needs an account, a subscription, or a download. Settings paths are current as of iOS 26; on older versions the names are close but the menus sit one level deeper.
1. App Limits: a daily quota per app
This is the one most people mean by “blocking an app.” You give an app a daily allowance, and once you spend it the app stops opening.
- Open Settings → Screen Time.
- Tap App & Website Activity, then Turn On App & Website Activity if it isn’t already on. Nothing else in Screen Time works without it.
- Tap App Limits → Add Limit.
- Pick a category — Social, Games, Entertainment — or tap the category name to drill down and select individual apps.
- Tap Next, set the time, and optionally Customize Days to allow more on weekends.
One thing to know before you rely on it: Apple states it plainly in its own documentation — by default, Screen Time limits can be ignored once reached. When the limit screen appears, so does a way past it.
2. Downtime: block apps on a schedule
Downtime blocks apps and their notifications across a window of time rather than a quota. It is the stronger of the two, because you set it once while calm and it fires on its own.
- Settings → Screen Time → Downtime.
- Tap Turn On Downtime Until Tomorrow for a one-off, or Scheduled for a recurring window.
- Choose Every Day or Customize Days, then set start and end times.
- Turn on Block at Downtime. Without it, blocked apps are only dimmed and you can carry on using them; with it, they can’t be opened at all.
- Use Always Allowed to keep Phone, Messages, or specific contacts reachable throughout.
Block at Downtime requires a Screen Time passcode (Settings → Screen Time → Lock Screen Time Settings). That passcode is what turns a suggestion into a block — with one caveat, covered below.
3. Lock or hide an app behind Face ID
Touch and hold an app icon on the Home Screen until the menu opens, then tap Require Face ID (or Touch ID, or Passcode). The app now asks for authentication every time, and relocks the moment you quit it. On the same menu, Hide and Require Face ID moves the app off the Home Screen entirely, into a Hidden folder at the bottom of App Library.
A handful of built-in apps can’t be locked — Calculator, Camera, Clock, Contacts, Find My, Maps, Shortcuts and Settings — and only apps you downloaded yourself can be hidden. This is the right tool for handing your unlocked phone to someone else, and a weak one for blocking yourself: you are the face the lock is waiting for.
4. Content & Privacy Restrictions: take the app off the phone
Go to Settings → Screen Time → Content & Privacy Restrictions and turn it on. Under Allowed Apps & Features, switching off a built-in app removes it from the Home Screen until you switch it back — Safari and Mail included. Under App Store, Media, Web, & Games → Web Content, choosing Limit Adult Websites unlocks a Never Allow list where you block individual sites by URL. It is also where you stop new installs, which closes the reinstall loophole below.
5. Block a contact, or limit who can reach you
For one person: Settings → Privacy & Security → Blocked Contacts → Add Blocked Contact. Their calls, FaceTime calls and messages stop arriving. For something broader, Settings → Screen Time → Communication Limits lets you narrow who can reach you during the day and, separately, during downtime — down to a short list of specific contacts.
6. Delete it, or lock the phone to one app
The bluntest option still works. Touch and hold the icon, tap Remove App, then Remove from Home Screen to keep it in App Library, or Delete App to remove it and its data. Most feeds stay signed in and can be reached from Safari, so pair it with a Never Allow entry if you mean it.
If you are handing the phone to a child for one specific thing, Guided Access is the tool nobody mentions: Settings → Accessibility → Guided Access, turn it on, set a passcode, then open the app and start a session from the Accessibility Shortcut, Control Center, or Siri. The phone is locked to that one app until the passcode is entered. Genuinely airtight — for someone who doesn’t know the passcode.
Focus modes deserve a mention but not a promotion. Settings → Focus silences chosen apps and people, can swap you to a stripped-down Home Screen page, and can start on a schedule or at a location. Focus manages attention rather than access: the apps are still there, one tap away. It pairs with Downtime; it doesn’t replace it.
Key takeaways
- App Limits and Downtime are the two real blockers in Screen Time; everything else mostly hides or silences apps.
- Locking an app behind Face ID stops other people, not you — you are the one who can authenticate.
- Apple states plainly that Screen Time limits can be ignored once reached unless you lock them with a passcode.
- Every built-in method keeps its off switch on the same phone, which is why they work for a child and fade for yourself.
The thing all six have in common
Read the list back and a pattern shows up. Every one of these methods keeps its off switch on the phone you are trying to put down, and hands you the key to it.
An App Limit can be ignored the moment it appears. A Face ID lock opens for your face. A deleted app is a search and a download away. And the Screen Time passcode — the one piece that makes any of it hold — is a four-digit code you chose yourself, that you can change in Settings, and that Screen Time Passcode Recovery will reset with your Apple Account if you forget it.
This isn’t a flaw. These are parental controls, and they were designed for two people: one who sets the limit and one who lives with it. In that arrangement the passcode is a real wall. It works. The trouble starts when both people are you — when the version of you who set the limit on Sunday has to be enforced by the version of you at 11pm on Thursday, who knows the code, holds the phone, and has a reason. Screen time isn’t a character flaw — it is what happens when the person enforcing the rule is also the person allowed to lift it.
The short version
Use Downtime with Block at Downtime for a real schedule, App Limits for quotas, and Guided Access when you hand the phone to someone else. All of them can be undone in Settings by whoever knows the passcode — which, when you’re blocking yourself, is you.
Moving the switch off the phone
If the weakness is that the off switch sits on the screen, the fix is to move it off the screen. That is the idea behind Norma: a stainless-steel disc you scan with your iPhone to block the apps you chose, and scan again to bring them back. No passcode, no “ignore,” no timer to argue with — the block only changes when the disc and the phone are in the same room. Leave it at home and the block holds. One-time purchase, and the same scan blocks distracting sites on your Mac. How that compares to software blockers, and what to try first if it’s the scrolling.
Questions, answered.
- How do I block apps on my iPhone?
- Go to Settings, tap Screen Time, tap App & Website Activity and turn it on, then tap App Limits and Add Limit. Pick a category or an individual app, set the daily time, and the app is blocked once you pass it. For a schedule instead of a quota, use Downtime in the same menu.
- How do I lock an app on my iPhone?
- Touch and hold the app icon on the Home Screen until the menu opens, then tap Require Face ID (or Touch ID or Passcode). The app then asks for authentication every time it is opened, and relocks when you quit it. Calculator, Camera, Clock, Contacts, Find My, Maps, Shortcuts and Settings cannot be locked this way.
- Can I block an app permanently on iPhone?
- Not with the built-in tools. The closest is Settings, Screen Time, Content & Privacy Restrictions, Allowed Apps & Features, which removes a built-in app from the Home Screen, or deleting a downloaded app outright. Both are reversible in under a minute by whoever knows the Screen Time passcode — which, if you set it up for yourself, is you.
- How do I restrict apps on iPhone without deleting them?
- Use App Limits for a daily quota, Downtime for a schedule, or Content & Privacy Restrictions to hide a built-in app from the Home Screen. All three leave the app and its data in place, and you can undo any of them in Settings.
- Why does my iPhone let me ignore an App Limit?
- Because that is the default. Apple notes that Screen Time limits can be ignored once reached unless you set a Screen Time passcode and turn on Block at Downtime. Even then, the passcode is one you chose yourself, and Screen Time Passcode Recovery can reset it with your Apple Account.
- How do I block distracting apps for myself, not for a child?
- The parental-control tools assume the person setting the limit and the person living with it are two different people. When they are the same person, the reliable approach is to put the switch somewhere your hand cannot reach in the moment — a scheduled Downtime you never touch, or a physical object like Norma that has to be scanned before anything changes.
Block the apps, not the impulse.
Scan a steel disc to switch the block on. Scan again when you actually mean to.
