About 1Blocker

1Blocker is one of the longest-running content blockers for Safari on Apple devices. It uses Apple's native content-blocking system, so all filtering happens on your device and Safari stays fast, with over 100,000 built-in rules for ads and tens of thousands of known trackers, plus filters for annoyances, cookie notices and social widgets. Custom rules let you block or allow specific sites and elements. A tracker firewall for apps on iOS extends protection beyond the browser. 1Blocker is free to download on the App Store for iPhone, iPad, Mac and Apple Vision Pro, with premium features unlocked by subscription or purchase that supports Universal Purchase and Family Sharing. Because it relies on Safari's content-blocker API, it is limited by Apple's rule caps and cannot inject scripts the way desktop extensions can, so some YouTube and anti-adblock tricks get through.

Best for: iPhone, iPad and Mac users who mostly browse in Safari.

Pros and cons

Why people leave
