1Blocker: Safari Ad Blocker for iPhone, iPad and Mac
Last updated: 5 October 2026
The 1Blocker ad blocker plugs into Safari on iPhone, iPad, Mac and Apple Vision Pro and stops ads, trackers, cookie notices and chat pop-ups before a page loads. The filtering happens on your own device, and the app never sees the pages you visit. The indie team behind it has been making 1Blocker since 2015, and it does not take money from advertisers to let their ads through.
The download is free and the free version lets you switch on one blocking category. 1Blocker Premium is £2.99 a month, £14.99 a year or £39.99 once, and one purchase covers all your Apple devices. Those prices come from the UK App Store, checked on 5 October 2026.
It works in Safari only, so ads in Chrome, Firefox or inside other apps are not blocked.

What the 1Blocker ad blocker does
Safari lets an app hand it a list of rules, and Safari then refuses to load anything on that list. 1Blocker writes and updates those lists. It does not open, read or change the pages you visit, so it has no record of where you go.
Because Safari does the blocking itself, there is no proxy and no VPN running in the background. The developer says pages open two to five times faster on average with it switched on. The filter lists update from the cloud each week without you doing anything.
The four blocking categories
- Block Ads: banners and other display ads, from a list of over 100,000 rules.
- Privacy Protection: over 50,000 known trackers, tracking cookies set by third-party sites, and fingerprinting scripts that build a profile from your browser and screen settings.
- Block Annoyances: cookie notices, marketing widgets and chat pop-ups.
- Block Adult Content: over 9,000 adult sites, which makes it useful on a phone or iPad that children use.
Free against Premium
The free version lets you switch on one category, for example Block Ads on its own. You can also allow ads on sites you want to support, straight from the Safari extension, and that allow list syncs between your devices through iCloud.
Premium switches on every category at once. It also adds custom rules: you can block any web address with a pattern, hide any part of a page by its CSS selector, and block cookies. Your settings and custom rules sync across iPhone, iPad and Mac through iCloud.
1Blocker prices in the UK
- Monthly: £2.99
- Yearly: £14.99
- Lifetime: £39.99, paid once
The yearly plan works out at about £1.25 a month. If you expect to keep it for three years or more, the lifetime price costs less than paying yearly. 1Blocker supports Universal Purchase and Family Sharing, so one payment covers your Mac and iPhone and can be shared with your Family Sharing group.
What it cannot block
Some sites serve ads in ways a Safari content blocker cannot stop, so you will still see the odd ad. It also has no effect outside Safari. Ads in Chrome or Firefox on an iPhone, and ads inside apps, carry on as normal.
If you want blocking that covers every app on a device, look at a filtering DNS service such as NextDNS, which works at network level. If you would rather switch browser, Brave blocks ads and trackers inside its own browser on iPhone, Android and desktop.
Setting it up
After installing, open the app and switch on the categories you want. Then turn on 1Blocker's content blockers in Safari's Extensions settings, which the app walks you through step by step. On a Mac, the same switches sit in Safari's Settings under Extensions. The 1Blocker for Mac app can also show you which companies tried to track you on each site.
