How to Block Porn on iPhone (So It Actually Stays Blocked)

There are plenty of ways to block porn on an iPhone, and Apple even ships one in Settings. The hard part was never the blocking. It's that every method can be undone by the same person who set it up: you. This guide covers each option, what it's good for, and how to close the "just turn it off" loophole.

The four ways to block porn on iPhone

1. Screen Time's built-in filter

Apple's own option: Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content → Limit Adult Websites. It filters adult sites in Safari and most other browsers, and as a bonus it switches off Safari's Private Browsing while it's active.

Good: built in, takes a minute, no downloads. Bad: you know your own Screen Time passcode, so turning it off takes the same minute. Coverage is patchy on newer sites, and apps are a separate battle. There's a reason "Limit Adult Websites not working" is one of the most-searched phrases in this space.

2. DNS filtering

Point your Wi-Fi network at a family-filter DNS provider (Settings → Wi-Fi → your network → Configure DNS → Manual), or install a filtering DNS profile so it covers cellular too. Adult domains stop resolving.

Good: works across apps and browsers. Bad: it's a settings field. Anyone who can set it can un-set it in ten seconds, and per-network setup means one new Wi-Fi network punches a hole in it.

3. Someone else holds the passcode

Screen Time restrictions genuinely hold when another person sets the passcode, so some people hand theirs to a partner or friend.

Bad: handing a passcode over is awkward, "Forgot Passcode?" resets it with your own Apple ID, and most people quietly get control back.

4. A Screen Time-based blocker app

A dedicated blocker app built on Apple's Screen Time technology enforces adult-content blocking system-wide, in every browser and every app, without you managing lists or settings. Blocking happens on the device itself, so nothing about your browsing needs to leave your phone.

This is the strongest blocking layer on iPhone. But on its own, it shares the same weakness as everything above: the off switch is still yours.

The real problem: you hold the keys

Be honest about how relapse happens. It's not that the filter failed to filter. It's that at some point (usually late at night) you decided to switch it off. A minute later everything is accessible again, nothing happened as a consequence, and by morning the blocker is back on like nothing occurred.

Blocking is a solved problem. Unblocking without consequence is the unsolved one. Any serious answer to "how do I block porn on my iPhone" has to answer "what happens when I try to unblock it?"

How Pledgely closes the loophole

Pledgely is a porn blocker for iPhone built around that exact question:

1. Enable the blocker. The app uses Apple's Screen Time technology to block adult content system-wide, in every browser and every app, including Safari.
2. Set your pledge. Sign in at pledgely.app and choose a daily amount that would genuinely sting, from $1 to $100. It's held on your card each day, not taken. The iPhone app handles the blocking, streaks, and milestones; your pledge lives on the web.
3. Live your life. Visiting a blocked site is never logged and never charged. The sites simply don't load. Pledgely collects zero browsing data.
4. Face the consequence. Turn the blocker off mid-cycle and your pledge is charged. Keep it on and the hold is released, so staying clean costs you nothing beyond the subscription.

Now the 2am decision isn't "toggle a switch." It's "pay real money to relapse." That's a different conversation with yourself, and it's the one that works.

Recommended setup

Pledgely with a pledge high enough to make you wince. Optionally layer DNS filtering underneath as a second net.

Willpower gets you through the moments the blocker doesn't cover. The blocker, with stakes behind it, gets you through the moments willpower doesn't.
