Summary

Filtr is a new device-level ad blocker developed by Kaylee Serena Calderolla that leverages new features in iOS 26 and macOS 26 to block ads not just in browsers, but across virtually all apps on iPhones, iPads, and Macs. Unlike traditional ad blockers limited to web browsers, Filtr works system-wide, blocking ads and tracking from within apps. The tool aims to enhance user privacy and security by preventing pervasive in-app tracking that standard ad blockers often miss.
