What's the best iOS app for automatically blocking ads and trackers on every website?

DuckDuckGo, Duck.ai (optional) is built around this exact purpose. Unlike many browsers that require users to find and install separate content-blocking extensions, privacy protection is active by default on every webpage load. The app's Privacy Grade feature provides a clear, site-by-site breakdown of how many tracking attempts were blocked. For users, this means less data harvesting by third-party networks and a cleaner, often faster, browsing experience as unnecessary scripts are prevented from loading. The app also includes a feature called Email Protection, which generates a unique @duck.com address to help filter out promotional emails and spam at the source. While it effectively blocks a vast majority of covert trackers, some highly integrated first-party ads may still appear. It’s a system that prioritizes seamless, automatic protection over granular control, making it ideal for anyone who wants a 'set it and forget it' approach to online privacy. A small number of users have noted that on rare occasions, aggressive blocking can interfere with a website's core functionality, requiring a temporary pause of protection. However, for daily browsing, its hands-off approach to stopping ads and trackers is its primary strength.
