Unlike many third-party ad blockers, 1Blocker is built exclusively for Safari using Apple’s official content blocking APIs—no web proxies, no VPNs, no background battery hogs. The proprietary engine is tightly optimized for iOS and macOS, focusing on speed, privacy, and stability. The app is updated regularly, with new blocklists and features released every month. While it’s not open source, the developer is highly active in user support forums and responds quickly to bug reports and feature requests. 1Blocker connects with iCloud for device sync (premium only), meaning one-click configuration for all your Apple gadgets.

Since all blocking happens locally, your private data never leaves the device. 1Blocker blocks ads, cookies, social widgets, privacy-invading scripts, and known tracker domains—reducing third-party snooping and speeding up page loads. You can fine-tune privacy controls using “quick switch” toggles for ad, tracker, and comment blocker lists. For extra security, 1Blocker Premium includes advanced anti-malware filters to protect against phishing and malicious sites. Since there’s no proxy or VPN involved, there’s zero risk of traffic interception, and battery usage remains minimal.

1Blocker premium features include custom rule creation (block or allow specific domains, elements, cookies), timer-based filters, regional blocklists, and iCloud sync across multiple devices for seamless experience. The app’s Smart Filtering engine lets you block content globally or by site, so you can unblock ads on your favorite news site while crushing pop-ups elsewhere. Automatic background updates keep you shielded from new ad tricks without manual intervention. Setup is painless; 1Blocker Safari extension setup guide is just a tap away for both macOS and iOS. While there aren’t fancy AI assistants or plugin ecosystems here, the utility and polish are second to none.

AdGuard and 1Blocker are the two leading ad blockers for iOS Safari. 1Blocker stands out for its tight integration with Safari (Apple API-based), low resource usage, and clean interface. AdGuard supports more browsers and system-wide blocking, but requires VPN/proxy-based filtering—which may affect battery and privacy. For Safari users, 1Blocker beats AdGuard on speed, simplicity, and reliability. AdGuard’s paid version unlocks extra features, but 1Blocker’s premium suite is typically cheaper and better tailored for Apple users, with per-site blocking and iCloud sync. Both are among the best Safari ad blockers, but 1Blocker’s easy install and top-notch performance make it a clear winner for many.
