How to block porn in Chrome on iPhone
Yes, you can block porn in Chrome on iPhone, and it is easier than it looks. Chrome on iPhone is not really the Chrome you know from a computer. Apple requires it to run on the same engine as Safari, which means the same iPhone-wide filters reach it. Here is what actually blocks porn in Chrome on an iPhone, including incognito mode.
Chrome on iPhone is Safari underneath
On a computer, Chrome runs its own engine and ignores Safari's settings. On iPhone, Apple does not allow that. Chrome on iPhone is Chrome's buttons sitting on top of Apple's engine, the same one Safari uses. The practical upshot is good news for you. A filter that works across the phone reaches Chrome too, so blocking it is not a separate project.
The methods that block porn in Chrome
Escape's blocking
Most porn blockers are Safari-only, so opening Chrome is the easiest way around them. Escape is built to cover every browser on the phone, Chrome included, and to stay on in Chrome's incognito mode where a lot of blockers switch off. So switching to Chrome does not switch the block off. Escape is on the App Store, free to download with no account. The deeper all-browser blocking is part of the premium tier.
Apple Screen Time
Settings, then Screen Time, then Content Restrictions, then Web Content, then Limit Adult Websites. Because Chrome uses Apple's engine, this applies in Chrome the same as in Safari. It catches the big sites and misses newer ones, so it works best as one layer. Set a passcode you do not hold yourself. Full setup guide.
DNS filtering
A network filter sits in front of every app, so it covers Chrome and everything else. It is the strongest single thing you can set up yourself. NextDNS walkthrough.
What about Chrome's incognito mode?
Chrome calls its private windows incognito. Incognito does not hide you from iPhone-wide filters like Screen Time or DNS, so those still apply. But many Safari-only blockers do switch off in incognito, which is why it is such a common bypass. The fix is blocking that stays on there, which Escape does. Open an incognito tab and try a blocked site to test whatever you are using. More on blocking private and incognito browsing.
Should you just delete Chrome?
For a lot of people early on, yes. One browser is one fewer path and one fewer decision at a bad moment. If you need Chrome for work or synced bookmarks, keep it and cover it with the methods above. There is nothing Chrome-specific to set up once the iPhone-wide filters are on.
