Blindfold vs 1Blocker: Comparing Two Safari Ad Blockers for iPhone & iPad

If you have used an iPhone for a while and care about blocking ads in Safari, 1Blocker is almost certainly on your shortlist. It has been on the App Store since the early days of iOS content blocking and gives power users a lot of switches to flip.

Blindfold is a newer blocker for iPhone and iPad built around full rule visibility, an on-device AI that catches new ads after a page loads, and interactive Safari tools for fixing broken pages or zapping clutter. Here is a fair comparison of where each app wins.

What 1Blocker does well

1Blocker has nearly a decade of history on Apple platforms. One purchase or subscription covers iPhone, iPad, Mac, and Vision Pro with iCloud sync.

Its main strength is granular category control: separate Safari extensions for Ads, Trackers, Annoyances, Adult Sites, Comments, and regional rules, plus 1Blocker Scripts and a custom rule builder in the app for URL blocks, CSS selectors, and regular expressions. For blocking outside Safari, its in-app Firewall uses a local VPN proxy on the device to block known tracker domains across other apps.

1Blocker’s free tier only lets you enable one filter category at a time. Premium unlocks all categories simultaneously, automatic updates, Scripts, and the Firewall for $2.99/month, $14.99/year, or $39.99 lifetime.

What Blindfold does differently

In day-to-day browsing on an iPhone, the differences between Blindfold and 1Blocker come down to four things:

Fixing broken elements right on the page (“Show what’s blocked”). When a strict filter rule breaks a checkout button, login modal, or video player in 1Blocker, you generally have to allowlist the whole site or guess which category caused it. In Blindfold, tapping Show what’s blocked in Safari reloads the page with every hidden element outlined in translucent amber boxes. Tap the amber box on the broken item to see the exact rule that matched it and allow just that element on that page, domain, or everywhere.
On-device AI and a live Element Zapper. Both apps apply 200,000+ native Safari rules during page load. When a site changes its markup and an ad slips through, Blindfold’s on-device AI (built on Apple’s on-device model) inspects suspicious elements after page load and writes an editable, domain-scoped CSS hiding rule on your iPhone. You can also tap Hide something on this page in Safari to tap any element, step up or down the HTML container with - and +, and save a permanent rule without hand-writing CSS selectors.
Scroll-lock and App Store redirect guards. Blindfold automatically unlocks frozen scrolling when a blocked overlay leaves overflow: hidden on the page, auto-rejects supported cookie prompts, and includes Stay in Safari to stop scripts from bouncing you into the App Store (itms-apps://).
System-wide filtering without using your VPN slot. 1Blocker’s Firewall occupies your iPhone’s personal VPN slot. Blindfold Everywhere uses Apple’s URL Filter API on iOS 26 with private information retrieval, so it blocks ad and tracker connections across other apps without conflicting with a work or personal VPN. Blindfold also lets you subscribe directly to external .txt or JSON filter list URLs.

Which one should you pick

1Blocker costs less ($14.99/year or $39.99 lifetime versus Blindfold’s $19.99/year or $69.99 lifetime) and includes a Mac app in the same purchase. If you need Mac support included or run an older iOS version before iOS 26, 1Blocker is a proven choice.

If you are on iPhone and iPad running iOS 26 and want an on-device AI for new ads, an amber X-ray view (Show what’s blocked) to fix broken elements in seconds, protection against forced App Store redirects, and system-wide filtering that leaves your VPN slot free, try Blindfold free or get it on the App Store.
