Filtr launches as first device-level ad blocker for iOS 26 and macOS 26
Original: Filtr is a new privacy tool that blocks ads in almost every iPhone and Mac app
Why This Matters
First device-level ad blocker leveraging new Apple privacy features could reshape mobile advertising landscape
Developer Kaylee Serena Calderolla released Filtr, a new privacy tool that blocks ads across all iPhone, iPad, and Mac apps using Apple's new URL filters feature in iOS 26 and macOS 26. The $5 annual subscription service extends beyond browser-based ad blocking.
Filtr is created by Kaylee Serena Calderolla, developer of the popular Safari ad blocker Wipr. The tool utilizes Apple's new URL filters feature in iOS 26 and macOS 26 to block ads at the network level across all apps, not just browsers. Unlike traditional ad blockers limited to web browsing, Filtr prevents ads from loading in any iPhone, iPad, or Mac application. Calderolla states her apps "do not collect personal data" and don't require access to personal information. The developer described implementing Apple's URL filters as a "nightmare" due to documentation challenges. Early testing shows immediate results with apps loading without their usual ads, though some show greyed placeholder spaces where ads would have appeared. Filtr represents the first app to successfully utilize Apple's URL filters feature.
