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.

DeniedPixels is an app that finds nudity on web pages and covers it before you see it. Images, video, GIFs and even explicit words in page text, censored in real time as you browse. Everything runs on your iPhone. Nothing is uploaded and no browsing data is collected. Available as app and Safari extension. CHOOSE EXACTLY WHAT GETS COVERED 28 detection zones, each with its own toggle. Cover only explicit areas, or include faces, hands, feet and more. Set preferred sensitivity. Silhouette Masking covers a whole person along their outline instead of rectangles. 18 CENSORING STYLES Pixelate, Blur, Black Bar, Color Fill, Sticker, Noise, Glitch, Oil Paint, Redacted, Word Wall and Color Invert, plus seven animated styles: Static Noise, Scan Line, Spotlight, Shrinking, Permission Denied, Loading Bar and Pixel Wall. Every style is adjustable, and you can give each body part its own style. VIDEO, DONE PROPERLY Frame-accurate censoring that keeps up with playback, with minimum flickering or missing frames. Covers embedded video, GIFs and animated images. A loading placeholder keeps content hidden until it has been checked, so nothing flashes while a page loads. TEXT CENSORING Blacks out explicit words in page text. A built-in wordlist, your own additions, exceptions for medical or educational reading, and an on-device deep scan that catches writing which avoids obvious vocabulary. It never touches what you type. MODES Only Once: an image is permanently blocked after its first encounter. Decay: content degrades further each time you see it, until it is gone. Challenge: a number-guessing barrier before temporary access. Reverse: censor everything except the detected areas. Beta TV: the whole page pixelated, with one small window on the body part you chose. Red / Green Light: videos switch between visible and covered at random intervals, within limits you set. STAY LOCKED Self Lock puts your settings behind a password, a timer, or both. Shared Access lets someone you trust manage your settings remotely, and you can revoke it at any time. SITE BLOCKING A built-in blocklist of over 42,000 sites known for sensitive content, plus your own blacklist and whitelist. Or filter only on known sites and leave the rest of the web alone. PRIVACY All detection runs on your device with an on-device AI model. No images, URLs or browsing data are ever sent anywhere. ONE LICENCE, PHONE AND DESKTOP A subscription bought here also unlocks the desktop extension, so one purchase covers your phone and your computer. Requires iOS 17 or later.
