Blindfold vs AdGuard: Which Safari Ad Blocker Should You Use?
If you’ve searched for “AdGuard for iPhone” or you’re looking for an AdGuard alternative, you’re really choosing between two different ideas of what an ad blocker should do. AdGuard has been blocking ads across every platform it can reach since 2009, with more than 150 million users worldwide. Blindfold is a newer app built for one thing: Safari on iPhone and iPad, done as transparently as possible. Both are legitimate approaches. This is a fair look at where each one wins.
What AdGuard does well
AdGuard’s biggest advantage is that it doesn’t stop at Safari. Its free tier blocks ads and trackers inside Safari using a content blocker extension, the same basic mechanism Blindfold uses. But AdGuard Premium (sold as an in-app subscription) or AdGuard Pro (a separate one-time-purchase app) adds a DNS filtering module that routes your device’s traffic through a local VPN profile. That lets AdGuard filter ad and tracker requests coming from other apps too, not just what renders in Safari. If you spend a lot of time in apps with their own ad networks and you want one tool cutting down request traffic across all of them, that’s a real capability Blindfold doesn’t have.
AdGuard is also cross-platform. The same account covers Windows, macOS, Android, and iOS, which matters if your household isn’t all-Apple. And it has a long track record: over a decade of filter list maintenance, a large user base, and a business built specifically around ad blocking and privacy tools, not a side feature bolted onto something else.
Worth knowing before you subscribe: the DNS module that reaches beyond Safari is a premium feature, not part of the free app. AdGuard’s premium plans run as a monthly or annual subscription with a 7-day free trial, or you can buy AdGuard Pro as a one-time app purchase if you’d rather not subscribe. Either way, if system-wide filtering across every app on your phone is the goal, AdGuard is built for exactly that, and it’s worth being upfront that Blindfold isn’t trying to compete on that front.
What Blindfold does differently
Blindfold stays inside Safari on purpose. It uses Apple’s native content blocker API, the same mechanism AdGuard’s free Safari layer uses, and nothing else. There’s no VPN profile, no local proxy, no routing of your network traffic through anything. Safari gets handed a rule list and applies it while a page renders. That’s the entire mechanism.
This isn’t just a feature gap, it’s a real privacy tradeoff worth explaining honestly. A DNS or VPN-based blocker like AdGuard’s premium mode sees more of your traffic pass through its filtering engine, because that’s the only way to reach outside Safari and into other apps. AdGuard says that traffic isn’t logged or sent anywhere, and there’s no reason to doubt that. But structurally, a system that filters your traffic has to be in a position to see your traffic. A content blocker never is. Blindfold only ever touches what Safari itself renders, because that’s the boundary Apple’s content blocker API draws. If you want the broadest reach, that boundary is a limitation. If you want the smallest possible amount of your traffic passing through any third party’s code at all, it’s the point.
Inside that boundary, Blindfold adds a few things. Three curated lists (ads, trackers, and page clutter like cookie walls and sticky overlays) run natively with no page-load overhead. When something slips through, an on-device AI reviews it after the page finishes loading and writes a precise hiding rule, without uploading anything you browse. Every rule running in the app, the stock lists and anything the AI writes, is visible and editable, so you can see exactly what’s being blocked and why.
There’s also a smaller, practical difference: plenty of sites run scripts that detect an active ad blocker and throw up a wall asking you to turn it off before you can keep reading. Blindfold answers those detection scripts quietly in the background, so you’re not stuck choosing between the article and your protection.
Pricing is a 30-day free trial, then $7.99/year or $19.99 once for lifetime access with no subscription at all. Both options include Family Sharing and every feature, and there’s no account to create. Compared to AdGuard’s 7-day trial and ongoing subscription (or a separate one-time-purchase app if you want to avoid that), Blindfold’s lifetime option is the more direct one-time-buy path if that’s what you’re after.

Which one should you use
If what you actually want is broad filtering that follows you into other apps, not just Safari, and you don’t mind a VPN profile handling that traffic, AdGuard’s DNS mode covers more ground than Blindfold ever will. That’s a legitimate reason to pick it, and it’s the one thing about AdGuard this comparison isn’t going to argue you out of.
If what you want is fast, private Safari blocking where you can see exactly what’s running and why, without a VPN profile in the mix and without committing to a subscription forever, Blindfold is built for that specifically. It’s not trying to be everything AdGuard is. It’s trying to be the clearest, most transparent version of the one thing it does. Try it free for 30 days or get it on the App Store.
