How to Block Adult Sites on iPhone (2026)
The fastest free way to block adult sites on iPhone is Apple Screen Time: go to Settings > Screen Time > Content & Privacy Restrictions, turn it on, and set Web Content to Limit Adult Websites. Lock it with a passcode you do not know. If you have turned that off before, add a blocker with a turn-off wait.

Quick answer
Use Apple Screen Time first. It is free, already on your phone, and blocks a large number of adult sites in a few taps. Its one big limit is that it can be switched off instantly by anyone who knows the passcode. If that person is you, the block is only as strong as your weakest moment, so plan for that from the start.
Block adult sites with Apple's free Screen Time
Menu names vary a little between iOS versions. On some versions, Content Restrictions is called App Store, Media, Web & Games. The options inside are the same.
- Open Settings and tap Screen Time. If it is off, turn on App & Website Activity.
- Tap Content & Privacy Restrictions and switch the toggle on.
- Open Content Restrictions, then tap Web Content.
- Choose Limit Adult Websites. Add any site that still loads under Never Allow.
- Go back to Screen Time, tap Lock Screen Time Settings, and set a passcode. Ideally, let someone you trust type it so you do not know it.
While you are in Content & Privacy Restrictions, open iTunes & App Store Purchases and set Deleting Apps to Don't Allow. You can also set Installing Apps to Don't Allow for a while, so you cannot download a new browser on impulse.
Limits of the Screen Time method
Screen Time is a good start, but it has gaps worth knowing before you rely on it:
- It is a list, not a guarantee. Apple decides which sites count as adult. Some sites are missed, and you have to add them yourself.
- Apps are a separate door. The web filter does not block social or video apps that can show explicit images.
- The passcode is the only lock. If you know it, the filter is gone in seconds.
- There is no wait. Turning it off takes effect immediately, so there is no time for the urge to pass.
BlockMind, Covenant Eyes, Opal, Canopy, one sec, and NextDNS
These apps take different approaches. Features and prices change, so check each App Store listing before you decide. This table is a general guide, not a full review.
| App | Best for | Price | Strengths | Weaknesses |
|---|---|---|---|---|
| BlockMind | People who switch blocks off in weak moments | Subscription, see App Store | Adult sites blocked on every browser, app blocking, turn-off wait, Strict Mode, deletion protection | iPhone focused, requires a subscription |
| Covenant Eyes | People who want activity reports sent to someone they trust | Subscription, see App Store | Reporting plus filtering | Monitoring is not for everyone |
| Opal | Reducing distraction and screen time | Free and paid plans, see App Store | Focus sessions and app blocking | Built mainly for distraction, not adult sites |
| Canopy | Families and parents | Subscription, see App Store | Content filtering aimed at explicit images | Designed mainly for parental control |
| one sec | Slowing down impulsive app opens | Free and paid plans, see App Store | Adds a pause before opening apps | A pause, not a hard block |
| NextDNS | People comfortable with network settings | Free tier and paid plans | DNS filtering that is highly configurable | Technical setup, can be removed in Settings |
How to close common loopholes
Most blocks fail through a few predictable routes. Close them before you need to.
Other browsers
If adult sites still open in a browser other than Safari, test each browser you have installed and remove the ones you do not need. Set Installing Apps to Don't Allow in Screen Time while you settle in, so you cannot install a new one. A blocker that applies to every browser on the phone closes this gap for good. Our guide on how to block adult content on iPhone walks through the full setup.
Deleting the app
Most blocking apps stop working the moment they are deleted. In Screen Time, set Deleting Apps to Don't Allow. BlockMind also has deletion protection, which waits out a cooldown before it can be turned off, so deleting it on impulse is not an option.
Turning off Screen Time access
Screen Time restrictions can be switched off by anyone with the passcode. Have someone else set it, or store a random code somewhere inconvenient. For more strength, use a blocker with a turn-off wait. In BlockMind, turning protection off starts a cooldown you choose, from 15 minutes up to 24 hours, and Strict Mode locks settings completely for a period you pick. See iPhone app blocker with Strict Mode for how that works.
Block the apps that lead you there
Websites are only part of it. If a social or video app often leads you to explicit content, block it at your riskiest times, or entirely for a while. How to block apps on iPhone covers Screen Time App Limits, Downtime, and stronger options.
How BlockMind works
BlockMind is an iPhone app that blocks adult sites on every browser and the apps you choose. You can block apps right now, on a schedule, or after a daily limit. Turning protection off waits out a cooldown, Strict Mode locks your settings, and deletion protection keeps the app installed. When something is blocked, you see a short message from your past self. A limited emergency pass is there for real emergencies. Your streak grows day by day, and so does a house: a new one at the start, at 7 days, at 30 days, and a final house at 60 days.
