The three ways to block websites on iPhone

You can block websites on iPhone using Screen Time (built into iOS), a third-party app from the App Store, or your Wi-Fi router settings. Screen Time is the easiest option if you want to block sites on your device itself. Third-party apps give you more control over what gets blocked and why. Router-level blocking affects all devices on your network, which works best if you're managing a household.

Each method has a different purpose. Screen Time works when you're on cellular data or Wi-Fi. Router blocking only works when connected to that specific Wi-Fi network. Third-party apps sit somewhere in between — they work on your device but can be more flexible than Screen Time about what counts as blocked.

Key Takeaways

  • Screen Time, built into every iPhone, lets you block websites through Settings without installing anything extra.
  • You can set different restrictions for different times of day, or block sites permanently until you change the setting.
  • Third-party apps like Freedom and 1Blocker offer more detailed controls but require you to install them from the App Store.
  • Blocking at the router level affects every device on your Wi-Fi network, not just your iPhone.
  • Screen Time requires a Screen Time passcode to remove blocks, so you cannot accidentally unblock a site.

Using Screen Time to block websites

Screen Time is the simplest method because it comes with iOS and requires no extra apps. Open Settings, tap Screen Time, then tap App Limits or Content & Privacy Restrictions. Under Content & Privacy Restrictions, turn on the toggle, then go to Web Content. Choose Unrestricted Access, Limit Adult Websites, or Specific Websites Only.

If you choose Limit Adult Websites, iPhone filters out known adult sites automatically. If you choose Specific Websites Only, you build a list of sites you can visit — everything else is blocked. To add sites to either list, scroll down and tap Add a Website or Add a Website Under "Never Allow".

To block a specific website without allowing only certain sites, use the "Never Allow" section. Type the web address exactly as it appears — for example, example.com will block example.com and www.example.com, but typing www.example.com alone may not block the non-www version.

Once you set up blocks, create a Screen Time passcode in Settings > Screen Time > Use Screen Time Passcode. Without this passcode, anyone with your phone can remove the blocks. If you forget the passcode, you have to reset your iPhone.

Blocking websites with third-party apps

Apps like Freedom, 1Blocker, and Cold Turkey offer more detailed blocking options than Screen Time. These apps let you block sites on a schedule, see reports of what you tried to visit, and sometimes block apps at the same time. Search the App Store for "website blocker" to see current options.

Most third-party blockers work by installing a VPN profile or content filter on your device. This means they can block sites even when you switch between Wi-Fi and cellular data. Some apps charge a monthly subscription; others are free with limited features.

The trade-off is that third-party apps require more setup than Screen Time. You have to install the app, configure which sites to block, and often create an account. Some apps also drain battery faster because they monitor your traffic constantly.

Blocking websites through your Wi-Fi router

If you want to block websites for everyone on your home network, you can do it through your router settings instead of on individual devices. Log into your router's admin page — usually 192.168.1.1 or 192.168.0.1 in a web browser — and look for Parental Controls, Content Filtering, or Access Control.

Router blocking works on any device connected to that Wi-Fi network, including iPhones, computers, and tablets. The blocked sites stay blocked even if someone tries to unblock them on their device, because the router itself is refusing the connection.

The downside is that router blocking only works on your home Wi-Fi. Once someone leaves the network or switches to cellular data, the blocks no longer apply. Also, router settings vary widely by manufacturer — you may need to check your router's manual or contact your internet provider for help.

What happens when you try to visit a blocked website

When you try to open a blocked site on iPhone, you see a message saying the site is restricted. With Screen Time, the message says "This website is restricted" and offers a button to request access. If you tap Request, the device asks for your Screen Time passcode — if you don't have one set, you can bypass the block immediately.

With third-party apps, the message varies depending on which app you use. Some show a full-screen blocker; others just prevent the page from loading. The exact wording and options depend on the app you installed.

If a site is blocked at the router level, your iPhone shows a generic error message like "Cannot connect to server" — it looks like the site is down, not blocked. This is why router blocking is harder to bypass by accident.

Blocking websites for a specific time period

Screen Time lets you set App Limits that turn on and off automatically. Go to Settings > Screen Time > App Limits, tap Add Limit, choose Web, and set the time window. For example, you can block websites from 9 p.m. to 6 a.m. every day, or only on weekdays.

When the time limit expires, the site becomes inaccessible until the window closes. You can set different limits for different days of the week. If you need to override the limit, you enter your Screen Time passcode.

Third-party apps often have more flexible scheduling. Some let you block sites only during work hours, or only on certain days, or with different rules for different sites. Check the app's settings to see what scheduling options it offers.

Removing or changing website blocks

To remove a block in Screen Time, go back to Settings > Screen Time > Content & Privacy Restrictions > Web Content and delete the site from your list. If you set a Screen Time passcode, you need to enter it to make changes.

If you forgot your Screen Time passcode, you have to reset your iPhone. Go to Settings > General > Reset > Erase All Content and Settings. This erases everything on your phone, so back up first if you have data you want to keep.

For third-party apps, open the app and remove the site from your blocked list. Most apps let you do this without a passcode, so if you want to prevent accidental unblocking, set a passcode within the app itself — not all apps offer this feature.

Frequently Asked Questions

Can someone bypass a website block on iPhone?

If you set a Screen Time passcode, they cannot bypass it without knowing the code. If you did not set a passcode, anyone with your phone can remove the block by going back to Settings. Third-party apps vary — some require a passcode, others do not. Router-level blocks cannot be bypassed on that Wi-Fi network, but they do not apply to cellular data.

Will blocking a website on my iPhone block it on my iPad too?

Only if you use the same Apple ID on both devices and have Screen Time synced across them. Third-party apps install separately on each device, so you have to set them up on both. Router blocking affects all devices on that Wi-Fi network automatically.

Can I block a website only during certain hours?

Yes, with Screen Time App Limits. Set a limit for the Web category and choose which days and times it applies. Third-party apps often have more detailed scheduling options. Router blocking is usually always on or always off — most routers do not support time-based rules.

What is the difference between blocking a website and limiting screen time?

Blocking a website prevents you from visiting it at all. Limiting screen time lets you visit the site, but only for a set amount of time per day before it becomes inaccessible. Screen Time can do both — you can block specific sites and also set daily time limits for categories like Social Media or Entertainment.

Does blocking a website use more battery?

Screen Time has minimal battery impact. Third-party apps that use a VPN profile or content filter may drain battery faster because they monitor all your network traffic. Router blocking has no battery impact on your iPhone because the blocking happens on the router, not your device.
