How to block porn on iPhone: the complete guide

To block porn on iPhone, turn on Escape's free Safari blocker, which blocks 40,000+ known adult sites with no account, and pair it with Apple's built-in Screen Time filter, Limit Adult Websites, behind a passcode someone else holds. Then add what your weak moments need. Premium's Deep Block extends the blocking to every browser and private tabs, app blocking locks the social apps no browser filter can see into, and Strict Mode makes turning blocking off wait 30, 60 or 120 minutes. The point is not to make porn impossible, but to add enough friction that the urge passes.

The short version

• Escape's Safari blocker: free, no account. Blocks 40,000+ known adult sites in Safari the moment you turn it on. The core of the setup.
• Apple Screen Time: built into iOS, free. Limit Adult Websites filters adult sites in Safari and the other browsers. Easy to set up, and easy to undo unless someone else holds the passcode.
• Escape Premium: Deep Block for every browser and private tabs, app blocking for the apps you pick, Strict Mode so blocking cannot be switched off on impulse, and Blocked Words for Safari searches.

Start with the two free layers, then add what your weak moments need. The point isn't to make porn impossible to reach. Anyone who is determined will find a way. The point is to add enough friction at 11pm on a Tuesday that "I'll just check" turns into "I'm going to bed."

Step 1: Escape's free Safari blocker

A Safari content blocker installs its own filtering into Safari, and by Apple's design it does the blocking without ever seeing what you browse. The blocking happens on your phone, and the app is never in the loop when you open a page.

Escape's blocker is built this way. It blocks 40,000+ known adult sites the moment you turn it on, it is free on iPhone, iPad and Mac, and there is no account, no name and no email. The App Store privacy label reads Data Not Collected. Escape on the App Store. Turning it on takes about two minutes: how to set up Escape's free Safari blocker.

Still choosing between apps? Here is how to pick the best porn blocker for iPhone, and the privacy questions to ask of any adult content blocker for iPhone.

Why a dedicated blocker on top of Screen Time?

• It's built for this one job. Apple's filter list is general. Escape's list is focused on adult sites, so it catches many that Apple's filter misses.
• It's visible. When Safari hits a blocked page, you see Apple's "blocked by content blocker" screen. That moment of seeing the page get refused can be the moment the urge breaks. Friction with feedback works better than silent filtering.

Step 2: Apple Screen Time, the built-in companion

Screen Time is Apple's built-in parental-controls system, but you can use it on yourself. It blocks adult websites in Safari, restricts certain App Store categories, and lets you set a passcode someone else holds (a partner, a friend, anyone you trust) so you can't easily undo it during a moment of weakness.

The full walkthrough, including the four common mistakes that defeat Screen Time, has its own page. The condensed version:

Setup, step by step

1. Open Settings → Screen Time.
2. If Screen Time isn't on already, tap App & Website Activity → Turn On App & Website Activity (on iOS 27 it is under Manage Screen Time; on iOS 17 and earlier, tap Turn On Screen Time).
3. Tap Content & Privacy Restrictions → toggle it on.
4. Tap App Store, Media, Web, & Games → Web Content (on iOS 17 the first row is called Store, Web, Siri & Game Center Content).
5. Choose Limit Adult Websites. iOS uses Apple's own filter list. It is far from perfect, but it catches the major sites.
6. Go back to the main Screen Time page and tap Lock Screen Time Settings (on iOS 27 it is under Manage Screen Time). Have someone else type the passcode. This is the single most important step. If you set the passcode yourself, you can take it off in thirty seconds.

What Screen Time catches

Most major adult sites in Safari. The big ones, the obvious search results, the redirects from social-media links. It also covers Apple's other built-in apps that load web content (Mail, Messages, Notes if you tap a link).

What Screen Time misses

• Not third-party browsers, despite the myth. Chrome, Firefox and Brave on iPhone all run on Apple's WebKit engine, which means they do respect Screen Time's web-content filter. It's easy to assume the filter is Safari-only.
• The feeds inside social apps (Twitter/X, Reddit, Instagram). Their in-app browsers use WebKit, so links are filtered, but the feed itself isn't. If a thread has explicit images, Screen Time can't help you there. Locking the app can, which is what Step 4 covers.
• Sites Apple's filter doesn't know about. The list isn't public and isn't updated by you. New sites slip through.
• You, in a weak moment, with the passcode. If you set the passcode yourself, you'll remember it. The whole system is roughly as strong as the friction between you and the passcode.

Worth knowing

You can also use Screen Time to set App Limits (e.g. cap Twitter at 30 minutes a day) and Communication Limits. For recovery the App Limits piece is sometimes the bigger lever, because relapse paths often run through scrolling now, not direct search. The Late Night course walks through specifically how to use App Limits to lower scrolling at the worst hour.

Step 3: Deep Block, for every browser and private tabs

Screen Time's filter reaches every browser, but its list misses a lot. Escape's list is the deeper one, and the free version lives inside Safari, so Chrome, Brave, Firefox or a private tab can walk past it. Deep Block, part of Escape Premium on iPhone and iPad, closes that gap. It sits underneath all browsers, so the blocking extends to Chrome, Brave, Firefox, Edge and any other browser, and to private and incognito tabs. While Deep Block is on, the Safari extension toggles in Settings are locked, so the block cannot be quietly switched off there. How Deep Block works.

Step 4: Lock the apps, and make it hard to undo

• App blocking locks the apps you pick, like the social feeds no browser filter can see into. The Late-Night window locks them every night from 10pm to 6am, and the After-Work (5 to 8pm) and Quiet Morning (5 to 8am) windows cover other hard hours. How to block apps on iPhone.
• Strict Mode puts a wait of 30, 60 or 120 minutes between you and turning blocking off. You get the timer, not a toggle. Why that holds.
• Blocked Words stops any Safari search for a word you choose from loading. How to block words in Safari search.

All three are part of Escape Premium. Escape also guides you through Apple's own deletion lock: Screen Time's Deleting Apps set to Don't Allow, behind a passcode someone else holds. The deletion lock, step by step.

Looking for one setup that covers the whole phone? On iPhone, the honest version is Deep Block plus app blocking: every browser is filtered, and the apps you pick are locked rather than filtered.

Putting it together: the layered defense

The simplest stack:

1. Turn on Escape's Safari blocker. Free, about two minutes.
2. Set up Screen Time with someone else's passcode.
3. Add Deep Block if you use other browsers or private tabs, and app blocking for the apps that pull you in.
4. Turn on Strict Mode, so a weak moment has to wait out the timer.

This stack is not unbreakable. Nothing is. What it does is make every path to adult content take deliberate, multi-step effort: turn off Screen Time, wait out Strict Mode, switch off the blocker, then search. By the time you've done all of that, the urge has usually passed. That's the whole point.

The blocker is the start, not the finish. The work happens after the block hits, when the urge is still there but the easy outlet isn't. That's what the 90-second urge ritual is for, and what the recovery timeline describes hour by hour.

Frequently asked questions

Will third-party iPhone browsers like Brave or Firefox bypass these blocks?

Not Screen Time. On iOS, every browser is required by Apple to use WebKit underneath, which means Screen Time's web-content filter applies to all of them. Escape's free blocker is Safari-only, and Deep Block extends Escape's blocking to every browser and private tabs. More on blocking porn in Chrome, Brave, and Firefox on iPhone.

Can I block porn on iPhone for free?

Yes. Escape's Safari blocker is free, with no account and no subscription needed for the blocking itself, and Screen Time is built in. Deep Block, app blocking, Strict Mode and Blocked Words are the paid layers in Escape Premium.

Does Escape's blocker collect what I browse?

No. Escape hands Safari a list of sites, and Safari decides what to block, on your phone. The Escape app never sees the URLs you visit, there is no account, and the App Store label reads Data Not Collected. More on the Escape privacy posture →

What about iPhone parental controls for someone else?

If you're setting this up for a child or another family member, the same layers work. Use Family Sharing in Screen Time so the passcode is held by the parent's phone, not the child's. Apple's official family Screen Time guide walks through that flow.

Is blocking really enough?

Blocking by itself, no. Blocking is the front door. Recovery is everything that happens after the door is locked: what you do at the moment the urge hits, what you replace the habit with, how you talk to someone about it. The site you're reading is built around that part. Browse the 28 courses if you want a structured starting point, or read the hour-by-hour recovery timeline if you want to see what changes in the first week.

Escape blocks porn in Safari for free, extends to every browser with Deep Block, and adds a 90-second urge ritual, practice games that retrain how you meet an urge, and 28 short courses on identity and the long arc of recovery. No account, no personal tracking.
