If you want to know how to block websites on iPhone without Screen Time, the short answer is that you need a separate blocking layer. Safari does not include a general built-in per-site deny list outside Apple's Screen Time web content controls.
The practical alternatives are a Safari extension, a DNS filtering service, or a filter on the Wi-Fi network you control. They are not interchangeable. A Safari extension can be simple but may only cover Safari. DNS filtering can cover more traffic but needs careful setup. Router filtering works on one network and stops when the phone switches to mobile data or another Wi-Fi connection.
Short answer
Choose the narrowest block that covers the path you actually use
If you only open the distracting site in Safari, use a Safari extension that supports a custom block list. If you switch browsers or open the same domain inside apps, consider device-level DNS filtering. If the problem happens only at home, a router or home DNS filter may be enough.
Three ways to block websites without Screen Time
Use a Safari extension with a custom block list
Install a reputable Safari extension that explicitly supports blocking chosen domains or URLs. Enable it in Settings under Apps, Safari, then Extensions. Menu labels can vary by iOS version. Test the exact website in a new Safari tab after setup.
Use a DNS filtering service
A DNS filter can block selected domains before they load. Depending on the service, setup may use an app, a configuration profile, or network settings. Check whether the service covers both Wi-Fi and mobile data, and whether another VPN or encrypted DNS setting can bypass or conflict with it.
Filter the domain on your home network
Some routers and home DNS services can block selected domains for devices on that network. This is useful for a home study desk or evening routine, but the block normally ends when the iPhone uses mobile data or joins a different Wi-Fi network.
How to use a Safari extension for a simple block
- Choose a Safari extension that clearly says it supports custom website or domain blocking.
- Install it from the App Store and review its privacy information, pricing, and permissions.
- Open Settings, then Apps, Safari, and Extensions. Turn on the extension and grant only the access it needs.
- Add the distracting domain to the extension's block list. Add common variants if the extension treats them separately.
- Open a fresh Safari tab and test the site. Also test links opened from Messages, Mail, or another app if those are part of your habit.
Apple also supports Safari content blockers, but not every content blocker offers a personal deny list. Some focus on ads, trackers, images, or page resources. Confirm that the product blocks the websites you choose before paying for it.
When DNS filtering is the better option
Choose DNS filtering when a Safari-only block leaves an obvious route around the rule. It can be useful if you use several browsers, if distracting links open inside other apps, or if you want the same domain blocked across more of the phone.
DNS filtering is broader, not automatically stronger. Some apps use their own network methods, and VPNs, Private Relay, encrypted DNS, or another configuration profile can change what the filter sees. Follow the provider's current iPhone instructions and test every route you care about.
Why blocking the website may not stop the app
Blocking a social or video website does not necessarily block the matching iPhone app. The app may connect to several domains or use services that a simple website rule does not cover. Trying to guess and block every technical domain can also break login, messaging, media, or unrelated services.
If the native app is the main problem, use an app-specific tool instead. Start with how to block social media on iPhone or compare the best app blockers for iPhone. Keep the website block for the browser route rather than treating it as a complete app block.
Make the block hard enough without making browsing useless
A total browser block can interfere with research, maps, support pages, banking, tickets, study links, and work. Begin with the exact domains that create open-ended sessions. Keep useful browsing available and add a replacement for the moment you would usually visit the blocked site.
That replacement could be a reading list, notes, a flashcard deck, a saved course, a planning app, or a real offline break. The goal is not only to remove a website. It is to make the next intentional action easier to choose.
Test your website block before relying on it
Open the full domain and a saved deep link
Test the homepage, a specific post or video URL, and any mobile subdomain you normally use.
Try another browser and an in-app link
If either route loads the site, decide whether you need broader coverage or can remove that route from your setup.
Test Wi-Fi and mobile data
A home-network block may work perfectly on Wi-Fi and disappear as soon as the phone switches networks.
Keep a safe way to change the rule
Know how to disable or edit the filter if it blocks a site you genuinely need for study, work, travel, finance, or support.
Use your phone on purpose
Use website blocking for domains and Timo for intentional app access
Timo is not a dedicated website or domain blocker. It is built for the app-access decision: reduce distracting phone time, grow useful phone time, name a reason before access, choose a duration, and track the balance.
If the browser is the route to a distracting site, use one of the website-blocking methods above. If native apps are the route, Timo can add intention before app access. Timo requires an active Pro subscription to use its app features. Pricing, trial details, and subscription terms are shown before purchase through Apple's In-App Purchase system.

Questions people ask
Can you block websites on iPhone without Screen Time?
Yes. Use a Safari extension with a custom block list, a DNS filtering service, or filtering on a home network. Test the browsers and networks you actually use.
Does Safari have a built-in website block list without Screen Time?
Safari does not provide a general built-in per-site deny list outside Screen Time. Apple supports third-party Safari extensions and content blockers, but you need one that includes custom website blocking.
Will a Safari extension block websites in every iPhone browser?
Not necessarily. A Safari extension normally applies to Safari. Check the product's coverage or use device-level DNS filtering if you need a broader block.
Can Timo block websites on iPhone?
Timo should not be treated as a dedicated website or domain blocker. It adds intention before distracting app access and helps you reduce distracting phone time while growing useful phone time. Timo requires an active Pro subscription to use its app features.
