If you’ve ever wondered how to block websites on iPhone for yourself or someone in your care, you’re in the right place. Whether you want to curb distractions, limit adult content, or protect young users from inappropriate pages, iOS offers built-in tools and third-party solutions to help you take control. In this guide you’ll find four effective methods—Screen Time, Safari content blockers, DNS filtering, and the mSpy app—so you can choose the approach that fits your needs and tech comfort level.
Use Screen Time to block websites
Screen Time is Apple’s native feature for monitoring and restricting app and web access. It runs at the system level, so once you set it up, any attempt to visit a blocked site in Safari or other browsers will be denied.
- Open Settings and tap Screen Time, then choose This is My iPhone or This is My Child’s iPhone.
- Tap Use Screen Time Passcode, enter a four-digit code, and confirm.
- Select Content & Privacy Restrictions and enable the toggle.
- Tap Content Restrictions > Web Content.
- Choose Limit Adult Websites to block common adult sites and add custom URLs under Never Allow, or select Allowed Websites Only to whitelist specific domains.
Once configured, Screen Time will also generate weekly reports showing which sites were attempted. You can combine web limits with Downtime—a schedule that suspends internet access during set hours—to reinforce your rules without micromanaging each day.
Install a Safari content blocker
Safari supports third-party extensions that filter pages as you browse. These apps use Apple’s Content Blocker API, which can improve page load times and block trackers in addition to unwanted sites.
To get started:
- Open the App Store on your iPhone.
- Search for “content blocker” or a specific name like AdGuard, 1Blocker, or Wipr.
- Install your chosen app.
After installation, enable it:
- Go to Settings > Safari > Content Blockers.
- Toggle on the blocker you installed.
- Relaunch Safari for changes to take effect.
Recommended Safari blockers:
- AdGuard – comprehensive filters and custom lists
- 1Blocker – user-friendly rules and preloaded sets
- Wipr – automatic updates and minimal setup
These extensions work only in Safari, but they offer granular control and can be turned on or off instantly.
Configure a DNS-based filter
DNS filtering blocks unwanted sites before your device even loads them. By pointing your iPhone to a family-friendly DNS service, you can filter categories like adult, social media, or malicious content across all browsers and many apps.
Popular DNS options include OpenDNS FamilyShield, CleanBrowsing, and Cloudflare’s Family DNS. To set one up:
- Open Settings and tap Wi-Fi.
- Tap the information icon (i) next to your network.
- Under Configure DNS, select Manual.
- Delete existing entries and add the DNS addresses provided by your chosen service.
- Tap Save.
Now any DNS request for a blocked category will fail, effectively preventing page loads. Note that this change applies per Wi-Fi network; for cellular data you can use a VPN app that lets you specify DNS servers or set up filters on your home router for broader coverage.
Block websites with mSpy
If you need remote management, deeper monitoring, and automatic enforcement, mSpy is a powerful third-party solution. It runs in the background and lets you control web access from an online dashboard:
- Sign up for an mSpy account and install the app on the target iPhone following the step-by-step guide.
- Log in to your mSpy control panel on any browser.
- Navigate to the Block websites section under Controls.
- Enter the domains you want to block or choose from preset categories.
- Set schedules for when sites should be inaccessible.
Unlike Screen Time or Safari blockers, mSpy applies restrictions across all browsers and can’t be removed without your dashboard password. You’ll also gain insights into browsing history, social media activity, and even recovered messages, making it a versatile tool for both parental oversight and relationship monitoring.
Frequently asked questions
Open Settings > Screen Time > Content & Privacy Restrictions > Content Restrictions > Web Content. Either remove the site from Never Allow or switch back to Unrestricted Access. For Safari blockers, go to Settings > Safari > Content Blockers and toggle off the extension.
Screen Time’s web restrictions apply to Safari and most WebKit-based browsers. Some third-party browsers may bypass these rules, so it’s wise to combine Screen Time with a DNS filter or mSpy for system-wide coverage.
Determined users might try deleting extensions, changing DNS settings, or creating new user profiles. Always protect Settings and Screen Time with a passcode. For stronger enforcement, use mSpy’s stealth mode and remote-lock features.
mSpy intercepts web requests at the system level. Once installed and configured via your mSpy dashboard, any attempt to visit a blocked URL in any browser or supported app will be instantly denied, with denial logs sent to your account.
Yes—Wipr and some OpenDNS options are free. Apple’s Screen Time is built in at no extra cost. Paid solutions like AdGuard Pro or mSpy offer advanced filters, scheduling and remote controls for a subscription fee.
Conclusion
Blocking websites on your iPhone is easier than you might think. Use Screen Time for basic, built-in controls, add a Safari content blocker for browser-specific filtering, configure a DNS filter for network-wide protection, or choose mSpy for remote enforcement and comprehensive monitoring. Pick the method that best matches your goals and tech comfort, set up the restrictions, and enjoy a more focused, secure mobile experience.
