For many adults, Screen Time’s free Limit Adult Websites setting is enough to stop drifting into porn on an iPhone, as long as you set a passcode you can’t easily look up. A paid blocker earns its price if you keep switching Screen Time off, need the same protection on Windows, Android or a Chromebook, want explicit images filtered on sites that aren’t blocked outright, or want reports sent to someone you trust.
Here’s what each option does, where each falls short, and a simple way to decide.
What Screen Time does #
Screen Time is built into every iPhone and iPad. Apple’s support page walks through the Web Content setting under Content & Privacy Restrictions, which offers three levels:
- Unrestricted: no filtering.
- Limit Adult Websites: Apple’s automatic filter for adult sites.
- Only Approved Websites: blocks everything except sites on an approved list.
The path is Settings, then Screen Time, then Content & Privacy Restrictions, then App Store, Media, Web, & Games, then Web Content. Changing it asks for your Screen Time passcode. Full steps are in how to block porn on iPhone.
Strengths: free, already installed, no account with a third party, and nothing about your browsing goes to anyone else.
Where Screen Time falls short #
- You set the passcode. If you know it, undoing the filter takes seconds. The fix is to let someone else set it, or to write a random one down and store it somewhere inconvenient.
- It’s a list-based filter. Automatic filtering catches many adult sites but not all, and new or mixed-content sites slip through.
- It doesn’t tell anyone. There’s no report to a partner, which matters if accountability helps you.
- It’s Apple-only. It won’t cover a Windows laptop or an Android tablet.
- Social apps are separate. Suggestive content inside social media apps is governed by those apps’ own settings, not by a website filter.
What paid porn blockers add #
Paid blockers fill specific gaps. What each one adds, based on the companies’ own sites in September 2026:
| Feature | Screen Time | Paid examples |
|---|---|---|
| Blocks adult websites | Yes | All of them |
| Filters explicit images on sites that aren’t blocked | No | Canopy screens content in real time |
| Makes the filter harder to remove | Passcode only | Canopy’s removal prevention; BlockerX premium uninstall protection on Android and uninstall alerts on iOS |
| Reports to a partner | No | Covenant Eyes, Truple, Ever Accountable, Accountable2You |
| Works on Windows, Android, ChromeOS | No | Most of them; check each app’s list |
| Cost | Free | Free tier (BlockerX) to about $18 a month (Covenant Eyes) |
Screen Time, DNS filters and paid blockers side by side #
A family DNS filter sits between the two: free like Screen Time, but it covers other devices too.
| Screen Time | Family DNS filter | Paid blocker | |
|---|---|---|---|
| Price | Free | Free | Free tier to about $18/month |
| Devices | iPhone, iPad, Mac | Any device (router or per-device) | Varies; often phones and computers |
| How it blocks | Apple’s adult-site filter | Refuses to look up adult domains | Domain lists, real-time content filtering, or both |
| Hard to undo? | Only with a passcode you don’t know | No, easy to change | Some add tamper protection |
| Tells a partner? | No | No | Accountability tools do |

How to decide #
Work down this list and stop at the first “yes”:
- Do you only use an iPhone, and you’ve never switched Screen Time off during an urge? Screen Time plus SafeSearch is likely enough. Add a family DNS on your home Wi-Fi for other devices.
- Do you keep switching the filter off? Hand the Screen Time passcode to someone else first. If that’s not possible or doesn’t work, try a paid blocker with tamper protection.
- Do you need the same protection on Windows, Android or a Chromebook? A family DNS filter covers them for free. A paid blocker adds more control.
- Does explicit content reach you through sites that aren’t blocked outright? Consider a content-level filter like Canopy.
- Does knowing someone will see your activity help you? Choose an accountability tool. See Covenant Eyes alternatives for the options.

Make free Screen Time stronger #
Before you pay for anything, tighten the free setup:
- Let someone else set the Screen Time passcode. They don’t need to know why.
- Add Cloudflare’s free 1.1.1.1 app with the Families adult-content option. Cloudflare says the app applies on every network, including cellular.
- Set Google SafeSearch to Filter. Google notes it only covers Google Search, so it’s a layer, not a solution.
- Keep the phone out of the bedroom at night. The best filter is not having the device in hand.
Neither one stops the urge #
Screen Time and paid blockers both work by adding friction. That’s valuable: a few minutes of delay can outlast an urge. But you control your own device, so no block is absolute, and neither option addresses the stress, boredom or late-night routine that sets the urge off.
Full Clear is built for that other half. It isn’t a blocker; it logs each urge with the hour, mood and situation so you can see your pattern, and its free panic button walks you through breathing, your own reasons and a 90-second timer. There’s no account and nothing leaves your phone, so it works alongside Screen Time or any paid blocker.
Frequently asked questions #
Is Screen Time enough to block porn? #
For many people, yes, especially paired with SafeSearch and a passcode held by someone else. It’s less effective if you know the passcode, use non-Apple devices, or run into explicit content on sites that aren’t blocked outright.
Can you get around Screen Time’s adult website filter? #
Yes. Anyone who knows the passcode can switch it off, and automatic filters miss some sites. That’s why the passcode matters so much, and why some people add a DNS filter or a paid tool as a second layer.
Do I need a porn blocker if I already have Screen Time? #
Not necessarily. A paid blocker makes sense if you keep switching Screen Time off, need cross-platform coverage, want content-level filtering, or want reports sent to a partner. If none of those apply, the free setup may be all you need.
Is there a Screen Time equivalent on Android? #
Android’s closest free equivalent for your own phone is Private DNS with a family filter, such as Cloudflare’s family.cloudflare-dns.com, which blocks adult domains across the whole phone. Google Family Link is built for supervising children’s accounts rather than an adult’s own device.
