Start with Apple Screen Time, which is free and blocks many adult sites. If you keep switching it off, add a tool with friction or accountability. Forge Shield suits adults quitting for themselves (blocking plus a recovery app, a 60 second off-switch wait and optional partner alerts). Covenant Eyes and Ever Accountable focus on screenshot or activity reports to a partner. Canopy is strongest as a family filter.
There are two kinds of porn blocker. Filters stop the page loading. Accountability apps report what you did to someone you trust. The best setup for most adults uses a bit of both. Here's how the main iPhone options compare, using each app's own public information as of October 2026.
1. Apple Screen Time (free, built in)
The adult content filter that comes with every iPhone. Turn on Limit Adult Websites, add sites to Never Allow, and lock it with a passcode someone else types. Step-by-step guide here.
Good for: everyone, as a starting point. Watch out for: it misses some sites, and if you know the passcode it's easy to turn off. Nobody finds out if you do.
2. Forge Shield (part of Forge Pro)
Forge Shield for iPhone uses the same Apple Screen Time system, so it covers Safari and every other browser on your phone. It adds what the built-in setting doesn't: you can block any site or app you pick, all day or only at night, a 60 second wait before you can switch it off, and an optional email to an accountability partner if you do. Forge never sees which sites you visit. It's part of Forge Pro, with a 7-day free trial.
Forge is also a full recovery app: streak tracking, an urge-surfing timer, an AI coach and a 90-day plan, so blocking is one part of a bigger plan rather than the whole thing.
Good for: adults quitting porn (or shopping, social media and other habits) who want blocking plus support. Watch out for: it's a speed bump, not a lock. It doesn't send screenshots or browsing reports to anyone, by design. iPhone only.
3. Covenant Eyes
One of the longest-running accountability services. It's built around reports to an "ally" rather than pure blocking. Third-party pricing listings put it around $17 a month for an individual plan, but check their site for the current price.
Good for: people who want detailed reports going to a partner. Watch out for: some people find screenshot-style monitoring too invasive, and reviewers note the cost and cancellation process.
4. Canopy
A filtering app with a dedicated porn blocker for adults as well as parental controls. It filters websites, can limit screen time and includes removal prevention. It offers a free trial, and pricing is on its site.
Good for: families, or adults who mainly want a strong filter. Watch out for: it's built around filtering, not recovery support.
5. Ever Accountable
An accountability app that reports concerning activity to a partner using on-device detection. The App Store lists a 14-day free trial, and third-party reviews put it at about $14.99 a month or $129 a year.
Good for: people who want reports rather than hard blocks. Watch out for: reviewers describe it as built to report rather than to block, and some App Store reviewers mention gaps on Apple devices.
6. BlockerX
A blocker app focused on adult content, with free and premium tiers. Premium pricing varies a lot between sources, so check the in-app purchase list on the App Store.
Good for: people who want a dedicated blocker app. Watch out for: check what's free versus premium before you rely on it.

How to choose
- Start free. Turn on Screen Time today. It costs nothing.
- If you keep switching it off, you need friction or another person, not a stronger filter.
- Decide how much you want shared. Some people want a partner to see everything. Others only want them to know if the blocker comes off. Both are valid.
- Blocking alone rarely does it. Pair it with a plan for your hardest hour.
Frequently Asked Questions
What is the best free porn blocker for iPhone?
Apple's built-in Screen Time filter. Turn on Limit Adult Websites under Content & Privacy Restrictions and add extra sites to Never Allow.
What's the difference between a porn blocker and an accountability app?
A blocker stops pages loading. An accountability app reports activity to someone you trust. Many adults do best with a blocker plus some form of accountability.
Can porn blockers be bypassed?
Yes, any of them can be with enough effort. Good ones add friction and accountability so bypassing isn't quick or invisible. Be wary of any app that claims it can't be bypassed.
Does Forge Shield send screenshots to my partner?
No. Forge never sees what you visit. If you add a partner, they're only emailed when Shield is turned on or off.
Do I need a paid app to block porn on iPhone?
No. Screen Time is free and works well as a first step. Paid apps add things like app blocking schedules, off-switch delays, reports or recovery tools.
Which porn blocker is best for adults rather than kids?
Tools built for adults treat you as the one in control: they let you choose what's blocked and who knows. Forge Shield, Covenant Eyes and Ever Accountable are aimed at adults. Canopy covers both families and adults.
