New Filtr Tool Blocks Ads Across iPhone and Mac Apps Using URL Filters

Filtr, a new privacy tool developed by Kaylee Serena Calderolla, blocks ads in iPhone, iPad, and Mac apps using a feature called URL filters introduced in iOS 26 and macOS 26. Unlike traditional ad blockers that only work in browsers, Filtr operates at the device level, enhancing user privacy by preventing tracking without accessing user traffic data. The tool is a paid feature of the popular Wipr ad blocker, which has been updated to include this functionality. Users report significant improvements in their app experiences, with ads in various applications, including sports and transit apps, being effectively blocked. However, Filtr cannot block ads served through apps' own networks, such as YouTube and Instagram. The tool is available for a $5 annual subscription, and Calderolla has maintained a blocklist that is regularly updated. This development marks a significant advancement in ad-blocking technology for Apple devices.

Key Points: • Filtr blocks ads in iPhone and Mac apps using new URL filters in iOS 26 and macOS 26. • The tool enhances privacy by preventing tracking without accessing user traffic data. • Filtr is a paid feature of Wipr and costs $5 annually, significantly improving user experience.
