The Short Answer

You can block porn on iPhone for free with Screen Time. Turn on Content & Privacy Restrictions, set Web Content to Limit Adult Websites, and add anything it misses to the Never Allow list.
Who holds the passcode matters as much as the filter. Let someone you trust set a Screen Time passcode you don't know, and have them use their own Apple Account for passcode recovery. If the recovery account is yours, you can reset the passcode yourself.
Then close the side doors. Test every browser, block new app installs, and turn on the sensitive-content settings inside Instagram, Facebook, X and Reddit.
A blocker limits access; it can't reach desire. It buys you a pause at the moment you'd otherwise act. What fills that pause, and who knows you're fighting, is the rest of the work.
Every menu path here was checked against Apple's documentation on October 1, 2026. iOS 27 moved some of them, and the steps say where.

Here's how to block porn on iPhone: open Settings > Screen Time > Content & Privacy Restrictions, switch it on, then go to App Store, Media, Web, & Games > Web Content and choose Limit Adult Websites. Then ask someone you trust to lock it with a Screen Time passcode you don't know. It's built into iOS, it's free, and it takes about ten minutes.

Nearly every guide to this is written for parents setting up a child's phone. This one is for the adult who wants a filter on their own phone, which raises the problem those guides skip: if you know the passcode, the filter is a few taps from gone at 1am. So below you'll find who should hold the code, the loopholes adults actually use, and what a filter can't do.

Doing this on a calm afternoon is the kind of foresight Proverbs commends: "The prudent see danger and take refuge, but the simple keep going and pay the penalty" (Proverbs 22:3). You aren't planning to fail. You're deciding, with a clear head, what you'll find on your phone at midnight.

How do I block porn sites on my iPhone?

Use the filter built into Screen Time. Go to Settings > Screen Time > Content & Privacy Restrictions and switch it on. Tap App Store, Media, Web, & Games, then Web Content, and choose Limit Adult Websites. Add sites it misses under Never Allow, test it in every browser, then lock it with a passcode.

Turn on restrictions
Open Settings > Screen Time, tap Content & Privacy Restrictions and switch it on. On iOS 27 the screen is redesigned, but Content & Privacy Restrictions is still where you start.
Choose Limit Adult Websites
Tap App Store, Media, Web, & Games, then Web Content, and choose Limit Adult Websites. Apple's iPhone guides for iOS 18 and iOS 26 give this exact path.
Add what it misses
Under Never Allow, tap Add Website and enter any site you know you've used, plus the web versions of apps you're about to delete, so that deleting an app doesn't just send you to its website in Safari.
Test it safely
Don't test it by searching for porn. Add a harmless site such as example.com to Never Allow, then try to open it in Safari and in every other browser on your phone. A restricted-page message means the filter is working in that browser; if the page loads, that browser isn't covered.
Hand over the passcode
Set a Screen Time passcode last: Screen Time > Lock Screen Time Settings on iOS 18 and 26 (Apple), or Screen Time > Manage Screen Time > Lock Screen Time Settings on iOS 27 (Apple). Don't choose it yourself. The next section covers who should, and the one recovery setting that decides whether any of this holds.

Want it stricter? The same Web Content screen can allow only websites you approve and block everything else. It's heavy for daily life, but some people choose it for a season.

Who should hold the Screen Time passcode?

Someone you trust who isn't you: a friend, a mentor, a pastor, or your spouse if you've both agreed to it. They choose a four-digit code you don't see and enter their own Apple Account for passcode recovery. If the recovery account is yours, you can reset the passcode yourself whenever you want.

This is the loophole most guides skip. After a Screen Time passcode is set, iOS offers Screen Time Passcode Recovery: an Apple Account that can reset the passcode if it's forgotten. Apple recommends not skipping it, and for good reason, because without it a forgotten passcode can't be reset or removed. But if the recovery account is yours, your own Apple Account password resets the passcode, and the filter protects nothing. Apple notes that the recovery account can be a different Apple Account from the one signed in on the phone, such as a family member's.

Hand them the phone at the passcode screen and look away while they choose four digits they won't write anywhere you'll find them.
When iOS asks for Screen Time Passcode Recovery, they sign in with their own Apple Account, typing it themselves.
Agree on what happens when you ask for the code. A good passcode holder asks a question before handing anything over. Decide now whether a request means a call, a conversation, or a day's wait.
Agree how new apps get approved if you block installs (next section). A quick text naming the app is enough.

If you're married, talk it through before asking your spouse. Some want the role; others would rather not be the gatekeeper, and a friend or mentor can carry it instead. If you're under 18, ask a parent, youth pastor or school counselor to help you set this up.

“Two are better than one, because they have a good return for their labor: If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up.”

Ecclesiastes 4:9–10

The code is a small thing to ask of a friend. The larger gift is that someone now knows you're fighting this, and will notice if you go quiet.

How do I block porn sites on Chrome and other iPhone browsers?

Start with the same Screen Time filter, then test it. Apple has said the filter works in Safari and other apps, but its newer documentation only promises supported browser apps, so run the example.com test in every browser you have. Keep one browser that passes, delete the rest, and block new app installs.

Apple's 2024 parental-controls article said iOS filters adult content in Safari and other apps. Its iOS 27 documentation is more careful, describing its newest web controls as working in Safari and other supported browser apps without naming them. Rather than rely on either sentence, rely on the test.

Keep one browser. Delete any browser that fails the example.com test, and any you don't need.
Stop new browsers arriving. In Content & Privacy Restrictions, tap iTunes & App Store Purchases and set Installing Apps to Don't Allow before the passcode is locked. You'll need your passcode holder each time you want a new app, which is a small price for keeping a fresh browser off the phone.
Turn on SafeSearch. In Chrome or the Google app, go to google.com/safesearch and choose Filter, which Google says blocks explicit results; the default, Blur, only blurs explicit images. You can switch it back yourself, so treat it as an extra layer.

How do I block porn on Facebook, Instagram, X and Reddit?

Use each app's own setting, because Limit Adult Websites filters websites and Apple doesn't describe it as filtering what social apps show in their feeds. Set Instagram and Facebook's sensitive content to the lowest level, turn off sensitive media on X and NSFW content on Reddit, and delete any app you can't rein in.

App	Where the setting is	What to choose
Instagram	Profile > Menu > Content Preferences > Sensitive content	Less, then Confirm
Facebook	Menu > Settings & privacy > Settings > Content preferences > Sensitive content	Show less
X	On x.com: Settings and privacy > Privacy and safety > Content you see	Uncheck Display media that may contain sensitive content
Reddit	On reddit.com: your preferences > Content	Turn off Show NSFW Content (18+), then restart the app

X and Reddit both say their iPhone apps take these settings from the website (X, Reddit), so sign in on the web to change them. None of the four promises a clean feed: Instagram's control only covers accounts you don't follow, X notes that media it hasn't labeled may carry no warning, and Facebook's reduces rather than removes. Where an app won't behave, delete it and add its website to Never Allow, or give it a daily limit whose passcode someone else holds (App Limits on iOS 18 and 26, Time Allowances on iOS 27).

Images can also arrive by Messages or AirDrop. Turn on Settings > Privacy & Security > Sensitive Content Warning, which Apple says blurs photos and videos that may contain nudity before you view them, in Messages, AirDrop, FaceTime video messages and some other apps. You can still tap Show, so it's a speed bump, but a speed bump at 1am is worth having.

Should I add a DNS filter to block porn on my phone?

It's optional. A family DNS filter such as Cloudflare's free 1.1.1.1 for Families blocks adult domains for apps as well as browsers. Set it up in Cloudflare's 1.1.1.1 app rather than in Wi-Fi settings, which cover only one network. You can remove it as easily as you added it, so it adds friction rather than a lock.

Cloudflare's family addresses, 1.1.1.3 and 1.0.0.3, block malware and adult content. In the 1.1.1.1 app, open the menu, go to Advanced > Connection options, and under DNS settings pick the 1.1.1.1 for Families option that blocks adult content. Typed into Wi-Fi settings instead, the addresses work only on that network and not on cellular, Cloudflare notes. One catch: if you pay for iCloud+ and use Private Relay, Apple encrypts Safari's DNS lookups through its relays, so a DNS filter may not see Safari traffic at all. That's one more reason Screen Time stays the first layer.

How do I block porn on iPad?

The same way as on iPhone. iPadOS uses the same Screen Time settings: Content & Privacy Restrictions, then App Store, Media, Web, & Games, then Web Content and Limit Adult Websites, locked with a passcode someone else holds. Set it up on the iPad itself, then run the example.com test there too.

Apple's iPad guide gives the same path, and the iOS 27 changes above apply to iPadOS 27. On a Mac, the filter lives in System Settings > Screen Time > Content & Privacy > App Store, Media, Web, & Games (Apple). Any device you can reach at midnight belongs on the list, including the old phone in a drawer.

What can't a porn blocker do?

A blocker limits access. It can't reach desire, loneliness or the habit of reaching for your phone when you're tired, and any setting on a phone you own can be undone if you're determined enough. Treat the filter as a wall that buys you a pause, and decide now what you'll do with that pause.

Why blockers alone usually aren't enough is its own article. The short version is that a filter is an outer wall, and Proverbs points to an inner one.

“Like a city whose walls are broken through is a person who lacks self-control.”

Proverbs 25:28

That isn't a reason to skip the filter. When Jerusalem's rebuilders were threatened, Nehemiah records that "we prayed to our God and posted a guard day and night" (Nehemiah 4:9). He wasn't writing about phones, but the pairing is the point: prayer and practical guards work together. And the self-control Proverbs describes doesn't come from software. Paul says the grace of God "teaches us to say 'No' to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age" (Titus 2:11–12). A filter holds the door while that slower work goes on.

If something gets past the filter anyway, don't let one slip turn into a long night: what to do after a porn relapse walks through the first ten minutes, and how to stop a porn urge right now covers the moment before. The complete Christian porn recovery guide puts walls, people and a plan together.

Where PrayBreak fits (we make it)

Everything above is free and built into iOS. We also make PrayBreak, an iPhone app (iOS 18 or later, rated 16+, a paid subscription after a free download) with two optional tools that run on the same Screen Time system. Adult Site Shield walks you through turning on this same Limit Adult Websites setting in five steps. The filtering is Apple's, PrayBreak can't see whether it's on, and the passcode advice above still applies. App Shield helps block apps you choose until you've prayed: finishing a prayer opens them for 5, 10, 15 or 20 minutes of use, then they're blocked again, even with PrayBreak closed. It has no partner key, so it's a pause you set for yourself rather than a lock someone else holds. For many people, a friend with the passcode and a deleted app will do the job.

Frequently Asked Questions

Is it free to block porn on my iPhone?

Yes. Limit Adult Websites, the Never Allow list, the Screen Time passcode and the app-install restriction are built into iOS at no cost, and Cloudflare's family DNS filter is free too. Paid apps add other features, but you don't need one for anything on this page.

Does Screen Time block porn in every app?

No. Limit Adult Websites is a website filter. Apple has said it works in Safari and other apps, but it isn't described as filtering what social apps show in their own feeds, and browser coverage can vary. Test each browser, use each social app's sensitive-content setting, and delete apps you can't filter.

Can I block porn on my phone without a passcode partner?

Yes, but know the limit: if the recovery account is yours, you can always reset the passcode. Pick a code you won't memorize and store it somewhere inconvenient, so switching the filter off takes effort. Then tell at least one person what you're doing; that adds what a setting can't.

Will Limit Adult Websites block every porn site?

No. Apple describes it as limiting access to many adult websites, not all of them. When something slips through, add it to Never Allow. Once the passcode is set, that needs the passcode too, so telling your passcode holder is how a gap gets closed instead of kept.

How do I block porn on Facebook on my iPhone?

In the Facebook app, open the menu, then Settings & privacy > Settings > Content preferences > Sensitive content, and choose Show less. Facebook says the setting covers friends, Pages you follow and suggested content in Feed and Reels. It reduces what you see; it can't promise a clean feed.

Can I block porn on an Android phone?

Yes, but the steps on this page are for iPhone and iPad. Android has its own built-in controls, and the SafeSearch and family DNS options above work on Android too.
