How to block apps on iPhone: every method, honestly ranked

If your iPhone runs iOS 27, two of the menus below have new names: Apple renamed Downtime to Screen Time Schedule and App Limits to Time Allowances. They work the same way — where this guide says Downtime or App Limits, look for the new name.

Apple gives you more blocking machinery than most people realise, and none of it is advertised well. Below is every method that actually works on a current iPhone, in the order most people should try them, with a straight account of what each one enforces and how it fails. Nothing here requires jailbreaking, and most of it is free.

One thing worth knowing before you start, because it saves you comparing marketing claims: on iOS there is no such thing as an app that blocks another app on its own. Every third-party blocker on iOS, ours included, works through Apple's Screen Time framework. That sets a shared ceiling. What separates the tools is not how strict the enforcement is — it cannot be — but what you have to do to turn it off.

All eight methods at a glance

Built-in free toolsScreen Time, Digital Wellbeing, Focus mode. You hold the passcode, so you can always undo them.

Software blockersSchedules and stricter modes, free or on a subscription. The unlock still depends on software you control.

ANOTHER ROOM

LOCKED

Physical keys and lockboxesA key you walk to and hold the phone against, or a box that holds the whole phone until a timer ends.

1. Screen Time App Limits (free, built in)

1. Open Settings and tap Screen Time.
2. Tap App Limits, then Add Limit.
3. Choose whole categories (Social, Entertainment, Games) or tap a category open and pick individual apps.
4. Set the daily allowance. Fifteen minutes is a more honest starting number than an hour.
5. Go back to the main Screen Time page and tap Lock Screen Time Settings, then set a passcode that is not your phone passcode.

When you hit the limit, the app dims and a screen appears offering to ignore the limit. That screen is the whole story: Apple deliberately includes an override so a limit can never lock you out of something you genuinely need. Because you set the passcode, you can always grant yourself more time.

Who this is right for: anyone who has not tried it. It is free, it takes two minutes, and for a large number of people a visible speed bump is genuinely enough. Do not buy anything until this has failed you.

How it gets bypassed

• "Ignore Limit" or "Ask For More Time" on the limit screen — one tap, by design.
• You know the passcode, so any limit can be edited or removed.
• If you set up Screen Time Passcode Recovery, your Apple Account can reset a forgotten passcode — so forgetting it on purpose does not hold either.
• Deleting and reinstalling the app can reset some limit behaviour.
• The blocked service is often still reachable in Safari.

2. Downtime (free, better than App Limits for evenings)

Screen Time's Downtime makes most apps unavailable on a schedule: only calls, messages and the apps you choose to allow stay open. Settings → Screen Time → Downtime, set a window, then use Always Allowed to keep Phone, Messages and Maps available.

One setting decides whether any of it holds: Block at Downtime. It appears once you have set a Screen Time passcode, and without it Downtime is a reminder — Apple's own guide says you can simply choose to carry on using the apps. Turn it on.

Downtime is underrated. Because it works by exception rather than by naming offenders, you do not have to predict which app will capture you tonight. It fails the same way App Limits does — you hold the passcode — but it fails less often, because you have to actively unwind a schedule rather than tap one button.

Keep the Always Allowed list short and boring. The temptation is to allow anything that might conceivably be needed, at which point the schedule allows everything and enforces nothing. Phone, Messages, Maps and your UPI app cover almost every genuine evening emergency.

3. Remove the app from the Home Screen (free, five seconds)

Long-press an app, choose Remove App, then Remove from Home Screen. The app stays installed and logged in, but it no longer exists as a shape your thumb knows the position of. You have to search for it deliberately.

This sounds trivial and it is surprisingly effective for a couple of weeks, because a great deal of phone use is muscle memory rather than intent. It stops working when your muscle memory relearns the swipe-down search. Treat it as a cheap first experiment, not a solution.

4. Guided Access (free, the strictest thing Apple ships)

Guided Access locks the iPhone into a single app until you enter a passcode or use Face ID. It is buried under Settings → Accessibility → Guided Access, and it is the only built-in feature that stops you leaving an app rather than stopping you opening one — which makes it the odd one out on this list, and the most useful of them for a specific job.

1. Settings → Accessibility → Guided Access, and turn it on.
2. Tap Passcode Settings → Set Guided Access Passcode. Use one you do not use elsewhere, or turn on Face ID for it.
3. Open the app you want to be stuck in — Kindle, a notes app, a lecture recording.
4. Triple-click the side button (or Home button) and press Start.
5. Triple-click again and enter the passcode to leave.

What it is genuinely good for: reading, revising from one document, handing your phone to a child, or a two-hour stretch where you know exactly which single app you need. Nothing else Apple ships enforces attention that hard, because nothing else removes the home screen entirely.

How it fails: you know the passcode, and leaving is three clicks and a Face ID glance away. It is also all-or-nothing — you get one app, not a working set — so it is unusable for a normal day where you need messages and maps but not Instagram. And it does not survive a restart, which is a thirty-second bypass anyone discovers by accident.

One caveat Apple states plainly: emergency calls and Crash Detection are unavailable while a Guided Access session is running, and you have to end the session to use them. That is worth weighing before you lock yourself into one app for two hours.

Worth knowing about anyway, because most guides to this subject skip it entirely, and for the narrow case of one app for one stretch it beats every other free option on this page.

5. Focus modes (free, good for context switching)

Settings → Focus lets you create a mode that silences notifications from chosen apps and can swap to a different Home Screen page showing only what you want available. Combined with a Home Screen page containing four useful apps and nothing else, this is the best free result you can get on iOS.

The limitation is that Focus hides and silences; it does not block. Anything you deliberately go looking for, you will find.

Pair it with Downtime rather than choosing between them. Focus removes the prompt — the badge, the banner, the icon in the corner of your eye — and Downtime handles the moment you go looking anyway. Most people only install one of the two and conclude the built-in tools are weak.

6. Shortcuts automation (free, more stubborn)

The Shortcuts app can run an automation when an app opens. A common pattern is: when Instagram opens, close it, or open a different app, or show a reminder. Shortcuts → Automation → New → App → choose the app → Is Opened → add the action.

This is more stubborn than a limit because there is no "ignore" button in the flow — you have to go and disable the automation. It is also fiddly, occasionally unreliable, and worth the effort only if you enjoy this sort of thing.

Two practical notes. The automation must be set to run without asking, or you are simply building yourself another dialog to tap through. And the exact menu wording moves between iOS versions, so if the path above does not match your phone, look for the Automation tab rather than assuming the feature is gone.

7. Third-party blockers (paid, varying strictness)

Dedicated blockers on iOS work through Apple's Screen Time APIs — the same underlying machinery, wrapped in a better interface with scheduling, cross-device sync and stricter modes. They cannot exceed what those APIs allow, which is a useful thing to know before comparing marketing claims.

Most charge a subscription. Some sell a physical device. The meaningful question is not how strict the marketing sounds but what the unlock depends on: if unlocking depends only on software you control, you are back to the symmetry problem.

A subscription has a second, quieter cost. You are renting a restriction, and the renewal notice arrives in the same inbox as the invitation to cancel it. Plenty of people discover they cancelled a focus subscription in exactly the mood the focus subscription existed to survive.

8. A physical key (paid, hardest to argue with)

The last category moves the unlock off the phone entirely. Blocking still runs on the device through Apple's official APIs — no app can block another app without them — but re-enabling means walking to a separate physical object and holding the phone against it.

This is what Spark does, and it is worth being precise about the mechanism. Locking is one tap in the app: no key required, no decision about duration, because hesitating to lock is the failure mode that ruins everything else. (It does need a Spark paired first — the app will not lock without one.) Unlocking is the only gated direction: you get up, go to the key and hold the phone against it for about fifteen seconds, or tap it if you have the NFC version. Nothing unlocks because the key happens to be nearby. Leave it in a drawer in another room and the cheapest route back to the feed is standing up.

Three things worth knowing up front. Turning Bluetooth off does not end a session — the lock is remembered on the phone and stays until you unlock it, and unlocking the Bluetooth key needs Bluetooth on and the phone held to the key. Deleting the Spark app does end a session: iOS allows it, and we would rather you read that here than discover it. And there are five emergency unlocks, for life — hidden if you turn on Strict mode — because a phone you genuinely cannot open is a liability rather than a discipline.

On the commercial side: the app is free and there is no subscription, though it is not in the App Store yet. The key is a one-time purchase in rupees, quoted ex-GST like everything else on this site, with free shipping to most of India and a replacement if it arrives damaged or faulty (report it within seven days). The Bluetooth key runs on a CR2032 coin cell and the NFC key has no battery at all, so there is no cable in the box and nothing to remember to charge.

It is not a cage, and we would rather say so than imply a guarantee we cannot keep. You own the phone; a determined person can always find a route — and the key itself is not cryptographic: the Bluetooth key's signal can be recorded and replayed, and the NFC key is a standard tag that can be copied. It is built to beat a moment of weakness, which in practice is the thing that actually beats you.

Unlocking

Hold your phone against the key — about 15 seconds for the Bluetooth Spark, a tap for the NFC one. Leave it in another room and the cheapest route back to the feed is standing up.

What to actually do

Start free. Set up Downtime with a short Always Allowed list, remove the two worst apps from your Home Screen, and give it a fortnight. If that holds, you are done and you have spent nothing.

If it does not hold, notice how it broke. If you kept tapping through the limit screen, you need the unlock to stop depending on your own judgement in the moment. If you simply stopped bothering to switch anything on, you need locking to be faster, not stricter.
