Key Takeaways
- iPhone has built-in website blocking through Screen Time. No app required to start.
- Open Settings → Screen Time → Content & Privacy → Web Content to enable.
- Block sites without Screen Time using a free DNS Profile (Method 3).
- Productivity adults and parents use the same five methods on iPhone.
You open Safari to check one thing and end up on Twitter for twenty minutes. Or your kid promised to do homework but the YouTube tab is open again. According to UC Irvine research from Dr. Gloria Mark, the average focused work session on a connected device now lasts just 47 seconds before interruption.
Yes, iPhone has built-in website blocking. Screen Time handles it natively, with no app required to start. This article covers how to block websites on iPhone in five practical methods: Screen Time Content Restrictions, blocking directly in Safari, DNS filtering for users who don’t want to use Screen Time, third-party apps with more granular control, and router-level blocking for the whole home network. For the broader parental controls picture, see iPhone parental controls.
What Is Website Blocking on iPhone?
Website blocking on iPhone is the system that prevents specific URLs from loading in Safari and other browsers. iPhone has it built in via Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content.
Because all iOS browsers (Safari, Chrome, Firefox) use Apple’s WebKit engine, a block set in Screen Time applies system-wide. This differs from Android, where each browser can behave separately. For users who don’t want to use Screen Time, methods like DNS filtering (Method 3) or third-party apps (Method 4) accomplish the same outcome through different paths.
5 Methods to Block Websites on iPhone
Five methods, depending on whether you want to use Apple’s built-in tools or skip them entirely. Method 1 is the default native answer (Screen Time). Methods 2 and 3 work alongside or instead of Screen Time. Method 4 is the third-party route for users who want more granular control. Method 5 covers the whole network at the router level.
Method 1: Block Websites on iPhone with Screen Time
Open Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content. Tap Limit Adult Websites to block adult content automatically, or tap Allowed Websites Only to whitelist specific sites. Add custom URLs to Never Allow for site-by-site blocking.
The default native answer for most readers.
1. Open Settings → Screen Time. If first time, tap Turn On Screen Time and set a Screen Time passcode different from your iPhone unlock passcode.
2. Tap Content & Privacy Restrictions and toggle on.
3. Tap Content Restrictions → Web Content.
4. Choose Limit Adult Websites for category filtering, or Allowed Websites Only for whitelist mode.
5. Scroll down and add specific URLs to Never Allow.
Limit Adult Websites uses Apple’s category list, which catches most adult content automatically. Custom URLs in Never Allow let you block specific sites by name. For what daily time limits to pair with this, see 4 screen time rules every parent should set. To remove blocks later, see how to turn off parental controls on iPhone.
Method 2: Block Websites Directly in Safari on iPhone
Safari on iPhone doesn’t have a standalone site blocker outside Screen Time. The closest direct option is Settings → Safari → Block All Cookies, which prevents most tracking sites from functioning. For specific URL blocking in Safari, use Method 1 since Safari inherits from Screen Time.
Safari on iPhone shares its blocking model with Screen Time. There’s no separate “block this site in Safari” toggle outside Content Restrictions. Chrome on iPhone uses Apple’s WebKit engine (same as Safari), so blocks set in Screen Time apply to Chrome too.
For the full Chrome breakdown including the desktop method (which works very differently), see block websites on Chrome.
What Safari can do by itself: block pop-ups (Settings → Safari → Block Pop-ups), block all cookies, hide your IP address from trackers. These are content and privacy controls, not URL blocking. For URL blocking, Screen Time (Method 1) is the answer.
Method 3: Block Websites on iPhone Without Screen Time (DNS Filtering)
To block websites on iPhone without using Screen Time, install a DNS Profile. Free services like CleanBrowsing, NextDNS, and OpenDNS provide installable iOS profiles that block adult content and malware system-wide. Setup is one download and one tap. The block is harder to remove than Screen Time.
The no-Screen-Time alternative. Right method when you want blocking that applies to every browser and every app on the phone, on both Wi-Fi and cellular, and that’s harder for a kid to disable than a Screen Time toggle.
1. Choose a DNS provider. CleanBrowsing Family (cleanbrowsing.org/filters) blocks adult content. NextDNS (nextdns.io) is most customizable. OpenDNS Family Shield is the simplest.
2. On the provider’s website, download the iOS configuration profile (.mobileconfig file).
3. Open the profile. Go to Settings → General → VPN & Device Management → Downloaded Profile. Tap Install.
4. Enter your iPhone passcode. The profile installs.
5. DNS filtering is now active across Wi-Fi AND cellular.
DNS Profile blocks apply across all browsers and apps. The trade-off: DNS blocks whole categories (adult content, gambling, social media) rather than specific URLs. For specific-URL blocking, combine DNS with Method 1.
Method 4: Block Websites with a Third-Party iPhone App
BlockSite, Freedom, and Opal are the most popular iPhone apps for website blocking with more granular control than Screen Time. They support time-based schedules, accountability features, and pairing across devices. All available free on the App Store with paid premium tiers.
The third-party option for users who want more than Screen Time offers. Productivity users especially gravitate here.
BlockSite: most popular cross-platform option. Blocks websites and apps. Free tier covers basics. Paid removes ads and adds unlimited sites.
Freedom: productivity-focused. Sync blocking schedules across iPhone, iPad, Mac, and Windows. “Locked Mode” prevents disabling during scheduled work hours.
Opal: newer focus-mode app with accountability features. Blocks specific apps and websites during scheduled focus sessions.
Steps for BlockSite (representative of all three):
1. Open the App Store and search for BlockSite. Tap Get to install.
2. Open BlockSite and grant the requested Screen Time access.
3. Tap the plus icon, enter a URL, and tap Save.
iPhone blocking apps work by requesting access to your Screen Time settings (Apple’s API requirement). This means they can read what you’ve set up in Screen Time and add their own blocks. Only install well-known apps with clear privacy policies.
Method 5: Block Websites on iPhone at the Router Level
Router-level blocking covers every device on the home network, including iPhones, iPads, and other family devices. Configure URL filtering in the router admin panel, or set the router’s DNS to a filtering service. Works when iPhone is on Wi-Fi but not on cellular.
The parent-with-multiple-devices method. Right answer for households where you want one block list to cover every device on Wi-Fi.
1. Open the router admin panel (usually 192.168.0.1 or 192.168.1.1) and sign in with admin credentials.
2. Find Parental Controls, URL Filter, or Access Control in the menu.
3. Add URLs to block. Most routers accept 10 to 20 URLs at a time.
4. Save and reboot the router if prompted.
Router blocking only applies on Wi-Fi. Once the iPhone switches to cellular data, the block doesn’t apply. Pair router blocking with Method 1 (Screen Time) or Method 3 (DNS Profile) for full coverage that follows the phone onto cellular networks.
For Parents: When Blocking Sites Isn’t the Full Answer
For older kids and teens, blocking sites is a useful layer in a larger setup. For younger children handed an iPhone or iPad for a video session, an endless block list often loses to the next unknown site they discover.
Instead of building and maintaining a block list, some parents skip the browser-level controls for younger kids and use a closed environment. An app where every piece of content has been pre-reviewed for safety, so there’s no list to maintain.
That’s what Jellies does. A video app for kids where every video is hand-reviewed by our team for safety, with no ads, no autoplay, and no comments. For parents with young kids, browsing what’s safe by design at jelliesapp.com is worth a look. It works alongside any block-list setup you have on the rest of the device.

Common Mistakes When Blocking Websites on iPhone
Three things commonly trip people up.
- Using the same passcode for Screen Time and iPhone unlock. If a child knows the unlock code, they know how to disable restrictions. Set a different Screen Time passcode that the child doesn’t know. Our kids bypass Screen Time post covers the workarounds children actually use against weaker setups.
- Blocking only the main URL. Many sites have mobile subdomains (m.example.com) or country versions (example.co.uk). Add all known variants, or use a DNS service that blocks the entire site family by category.
- Forgetting Screen Time syncs across iCloud devices. A block set on iPhone applies to iPad if both use the same Apple ID. Usually a feature, but causes confusion when an iPad block is “mysteriously” gone after toggling on iPhone. Turn off “Share Across Devices” in Screen Time to manage each device independently.
Wrapping Up
Five methods, depending on your setup. Screen Time for the default native answer. Safari direct settings for cookie and pop-up control. DNS filtering for blocking without Screen Time and across cellular. Third-party apps for more granular schedules. Router-level for whole-network coverage.
The fastest action right now: open Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content. 60-second test. For the Android side if your household has both platforms, see block websites on Android.
Frequently Asked Questions
Can I block websites on iPhone without Screen Time?
Yes. Use a DNS Profile (Method 3), install a third-party app like BlockSite (Method 4), or block at the router level (Method 5). All work without Screen Time turned on.
Why does my iPhone block list reset randomly?
Screen Time “Share Across Devices” is on, and another device on the same Apple ID changed the settings. Turn it off in Settings → Screen Time to manage each device independently.
Does the block work on Chrome and Firefox on iPhone?
Yes. All iOS browsers use Apple’s WebKit engine, so Screen Time blocks apply system-wide. Chrome and Firefox on iPhone are essentially Safari skins, unlike on Android where each browser is separate.
Can I block a website only during specific hours on iPhone?
Yes, with Downtime in Screen Time (Settings → Screen Time → Downtime). Or use a third-party app like Freedom or Opal which support more granular schedules. BlockSite supports schedules on its paid tier.
Can my child bypass a Screen Time website block?
Some workarounds exist (switching to mobile data if router-only, using a different Apple ID, guessing the Screen Time passcode). Combine Screen Time with DNS Profile and use a strong, unique Screen Time passcode.
