1Blocker lets you block obtrusive ads, sneaky trackers, and annoying elements on sites. With 1Blocker, you’re safe online and nothing will distract you from enjoying sites. 1Blocker is very easy to use — just flip a couple of switches to start blocking ads and trackers. The app will automatically receive cloud updates to the built-in filters silently, so you don’t need to do anything. It’s as simple as setting and forgetting. 1Blocker is a fully native app designed to extend Safari naturally. It’s lightweight and doesn’t drain your battery by taking up your device’s resources. The blocking itself is super fast because Safari does it itself. We only provide filters to Safari and don’t modify webpages in any way. This vastly improves efficiency because Safari knows in advance what should be blocked. So, with 1Blocker, sites load on average 2-5x faster. It’s important to note that not all ads can be blocked though. Some sites use techniques that make it impossible for us to block their ads using currently available features for Safari content blockers. SECURE BY DESIGN 1Blocker is secure and private. It doesn’t have access to webpages and doesn’t track you in any way. We believe that privacy is not for sale. That's why we don't have an "Acceptable Ads" program. We stay independent, and the only way we make money is through direct sales of 1Blocker in the App Store to you. ADVANCED CUSTOMIZATION 1Blocker is a highly customizable content blocker, providing the possibility to create powerful custom rules. It allows you to create custom rules that block any URL by providing a regular expression or hide any element by CSS. It also lets you block cookies. (Available in Premium) AVAILABLE ON ALL DEVICES 1Blocker is available for iPhone, iPad, and Mac. Your preferences and custom rules are always in sync through iCloud no matter which device you're using. FEATURED IN THE PRESS 1Blocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more. FEATURES AVAILABLE FOR FREE • The ability to enable one category (for example, Block Ads only) • Whitelisting sites right from the Safari extension • Whitelist synchronization between devices via iCloud FRIENDLY SUPPORT Send your feedback at @1BlockerApp on Twitter or via email. Your feedback is always very welcome and considered for the next release. We have been making 1Blocker since 2015. We believe it’s the best all-around package currently available in the App Store.

In-App tracking prevention
15/06/2021

I initially downloaded this app to block ads and learned after about the in-app tracking blocker. This will prevent first party app tracking. You really have no idea of how muck tracking is going on until you turn on the feature and check the logs. The free version will do a great job at blocking ads. The premium features work extremely well and have been worth the money for me. The app is really impressive. If you value your privacy it is worth looking in detail at what this app can do for you.

1Blocker; an app saves li

This app feels like putting a tiny research team in your pocket. From the moment you open it the layout is clean the tools are obvious and you never feel lost. Type in a claim a headline or a random “Is this actually true?” question and the app goes to work pulling in sources highlighting key facts and flagging anything that looks suspicious. It turns that messy chaos of information into something you can actually understand. What makes it stand out is how fast and transparent it is. You do not just get a yes or no answer. You see where the information came from why it is considered reliable and how different sources compare. That builds trust. You do not have to be a journalist or researcher to use it yet it still feels powerful enough for serious work. It turns everyday scrolling into informed scrolling. The real superpower of this app is how it fits into real life. You can fact check a headline before sharing it in a group chat double check a statistic before using it in a school assignment or quickly scan different viewpoints on a big global story. Notifications can highlight trending rumours and give you a clean breakdown of what is confirmed what is uncertain and what is straight up false. Instead of feeding panic it quietly feeds your brain. Introducing this app to the world is basically handing people a shield and a spotlight at the same time. A shield against misinformation and a spotlight on real verified knowledge. In a world where anyone can post anything this app gives you a calm clear way to say “Show me the facts.” It feels less like another app on your phone and more like an everyday superpower for thinking clearly speaking confidently and staying smart.

Disappointed. A long time user, now uninstalling.

I've been using this extension for at least the last couple of years. It's been unobtrusive and generally a 'nice to have' with the odd occasion where it would cause a page to not behave as expected, but was easily turned off temporarily. The newest update now requires you to pay a premium subscription for any more than one category (e.g. you can block ads or you can block trackers, but unless you pay the subscription you can't do both). This isn't a subscription for new features that weren't available before, this is a subscription for features that were included in the previous version. This isn't a 'need to have' as there are a number of other services out there that offer the same features, some of which are still completely free. So, while the extension does what it says, it has moved to a subscription model with no added benefit to the user. Because of this, I'll now be uninstalling and looking elsewhere.

Hello, thank you for making us aware of the situation. This is definitely not the way the app should work for you.We strived to avoid any negative impact on the existing customers, and the new app still offers the same conditions for you. You should have access to multiple blocking categories, custom rules, iCloud Sync, etc. at no extra cost. The rules are still updated with every 1Blocker release to the App Store, just like it was before.The app is supposed to sync your previous purchase automatically. However, if it doesn't let you turn on multiple categories, please, reinstall it and use the Restore Purchase button in the Settings > Premium section.If you still have any questions, please, let us know via any of the feedback buttons available in the app or our email (support@1blocker.com).We will meet you there and guide you through them!

Great, but new UI is awful
15/01/2025

Great app. I’ve used it for years and it does what it says well. But the latest update changed the UI and it’s worse than before. The main page used to give you a summary of what you had enabled, now it’s all obfuscated and hidden under weird menus. A good example is what used to be called Firewall. I get the name change, but now it’s no longer clear from the home page if it’s enabled or not. It’s hidden inside somewhere that I always forget. The problem is that because it creates a VPN profile, if you connect to a real VPN, this feature gets disabled. It’s now a pain to see quickly if it’s enabled or not, and then a further pain to enable it if it isn’t. Would be a five star app with the previous UI for sure.
