1Blocker vs Ka-Block!

1Blocker is an ad and content blocker for Apple devices, with Safari filtering, custom rules and options for tracker and cookie-popup blocking. Its Safari content blocker filters ads, cookie banners, annoyances and trackers; the separate 1Blocker Scripts extension targets harder-to-block ads and annoyances, including YouTube video ads. On iOS, an in-app tracking filter uses a local VPN profile to block invisible trackers across apps. 1Blocker says filtering happens locally and that the app does not collect personal information or track visited sites. Listed platforms are iOS, macOS and browser extension, with visionOS also supported. Requirements are iOS 16.0 or later and macOS 13.0 Ventura or later. Free mode permits one blocking filter at a time and custom rules. A 14-day trial is listed. Paid options are $2.99 a month, $14.99 a year and a lifetime plan listed at $39.99 a month, described as a one-time payment. Premium includes multiple categories, filter updates and in-app tracker protection.

Ka-Block! is a free Safari browser extension for blocking a curated selection of advertisements and trackers. It is available as an extension and on iOS and macOS, covering desktop and mobile devices while supporting only Safari. The project says blocking third-party scripts can reduce page-load time, data use and battery drain. Its filtering code makes zero network connections, and the extension does not access pages loaded by the browser. Apple’s listing reports that the developer says the app collects no data. Ka-Block! aims to block most ads and trackers without slowing pages, while acknowledging that some advertisements may remain. The blocked-domain list changes only when a new extension version is released, and custom filter lists are not supported. The project is open source under the MIT license. The listed plans cost nothing. iOS requires version 12.0 or later, and the listed App Store version is 3.5 from November 6, 2021.
