Best porn blockers for iPhone: a sourced 2026 comparison

Written by the developer of The Blocker, so we have a bias. We are not affiliated with the other products. Prices and features checked 28 September 2026 from each product’s website and US App Store listing; prices change. We do not show star ratings.

The short answer, by need

• Private and simple, for yourself: The Blocker in Safari plus Screen Time’s Limit Adult Websites. No account, no reports.
• Another person involved: Covenant Eyes (Victory) or Ever Accountable.
• Full parental control: Qustodio or Canopy.
• Focus across whole apps: Opal.
• Free, for all apps: CleanBrowsing or OpenDNS FamilyShield.

Side by side

Prices are in US dollars. US prices shown; the App Store shows the price for your country. Where a website and the US App Store differ, we list both. App Store pages often omit the billing period.

Each product in brief

The Blocker

A Safari blocker for iPhone and iPad, iOS 17.2 or later. Safari applies its rules on the device; the content blocker can’t see which pages you open. No account. The free app blocks adult sites and up to 10 sites you choose. Pro adds categories, unlimited sites, schedules and a delay to unblock. Limits: Safari only, no partner, and anyone with your Screen Time passcode can switch it off (our site).

Apple Screen Time

Built into iOS and free. Limit Adult Websites “limits access to many adult websites automatically” (Apple). Apple doesn’t publish which third-party browsers follow it. Turn on Content & Privacy Restrictions in Screen Time, then choose it under Web Content (iOS 26 steps). It is on by default for children under 18 (Apple). Apple suggests it for “simple or limited content-filtering needs”.

Covenant Eyes (Victory)

Now called Victory by Covenant Eyes. An ally you invite “sees where you go online” (Covenant Eyes). On iPhone, Victory Shield blocks “explicit domains in any app” and, with your permission, shares Safari screenshots with your ally (App Store). Stronger: reach across apps, a human ally, and apps for Mac, Android and Windows. Blurred screenshots and logged domains go to its servers for reports (privacy policy). Full comparison.

BlockerX

From its US App Store listing only (App Store). It describes protection “in both Safari and Chrome”, “daily browsing reports” to a partner, a panic switch, and alerts if the app is uninstalled or “the VPN is disabled”. Stronger: Chrome coverage and a partner. The download is free, but it “requires a subscription to access all features”. Its privacy label lists purchases, identifiers and usage data as “Data Used to Track You”.

Ever Accountable

An accountability service. An extension covers Safari. Before you open social apps or other browsers, you turn on its screen recording, and Apple’s Family Controls keep them locked until you do (Ever Accountable). An AI on the phone then checks the screen (its blog), with “No VPN” (App Store). A partner gets weekly reports; blocking is optional and off by default (plans). Data is stored temporarily on its server to build those reports (terms).

Canopy

A filtering and parental-control service. On iPhone you install Canopy Shield and an MDM profile (Canopy’s guide). Its AI “inspects images, videos and websites” before they appear (App Store). An Ally, human or AI, reviews requests to lower filters (Ally). Stronger: image and video filtering, parent tools, and apps for Android, Mac, Windows and Chromebook (pricing). Its policy covers device IDs and requested URLs (privacy policy).

Qustodio

Full parental control: web filtering, app blocking, time limits, reports and location (App Store). The kids app installs an MDM profile and a VPN, and can block unsupported browsers (kids app). On iOS, all data “is channeled through our servers” (terms). The free plan covers one device (Free vs Premium); paid plans start at $59.95 a year (pricing). Its App Store label lists data “Used to Track You”.

Opal

A focus app that uses Apple’s Screen Time API to block the apps and websites you choose. The App Store lists it as “Only for iPhone” (App Store). Each Block List has an Adult Blocking toggle (Opal help) that uses a list maintained by Apple (Opal help). Stronger: it blocks whole apps, and Pro’s Hard Mode is described as “No way out” (pricing). Its listing says “personal browsing data never leaves your device”.

CleanBrowsing

A DNS filter with free options. The Family filter blocks adult sites, proxy and VPN domains, and mixed sites like Reddit (filters). Install its profile or its app, which adds a VPN configuration (setup). A DNS setting can apply to every lookup on the device (Apple), so it reaches all apps. Free filters need no account but are throttled, with no support.

OpenDNS FamilyShield

A free DNS filter, “preconfigured to block adult content”, with “no sign-up required” (OpenDNS). Its guide recommends your home router, which covers every device on that network; its setup guide has no iPhone section (setup guide). On iPhone, DNS is set per Wi-Fi network (Apple), so it works on the networks where you set it.

How we chose, and our bias

We picked well-known tools of each kind and read their websites, US App Store pages and privacy policies. We did not test blocking, and we left out what we could not confirm. Our bias: we make The Blocker and value privacy and simplicity, but other tools are stronger for reach outside Safari, for involving another person and for parents. Found an error?

Which should you choose?

• Just for you, kept private: The Blocker plus Screen Time. Set it up, then make it harder to turn off.
• No budget: free ways to block porn on iPhone.
• Someone else involved: The Blocker vs Covenant Eyes.
• A child’s iPhone: Qustodio, Canopy, or our guide for a child’s iPhone.
• Whole apps: Opal. On iPad, see our iPad guide.
