1Blocker

1Blocker is a Safari content blocker rated 4.50 from 12,725 ratings, the largest rating base of any Safari blocker we checked, last updated 25 May 2026. It is free to download, then $2.99 a month, $14.99 a year, or $39.99 once for lifetime access — the pay-once route if you want the most configurable option rather than the cheapest. It is one of the few whose developer claims YouTube ad blocking, though that claim is scoped to Safari, it is the developer’s own, and no developer claims to block ads inside the native YouTube app.
