Using an ad blocker is good for your security, privacy, and even the FBI recommends them to defend from online harms. But as much as ad blockers are great for cleaning up your browsing experience, these tools often do little to prevent the pervasive tracking from ads within apps.
Now, thanks to a new feature in iOS 26 and macOS 26, one developer has built the first device-level ad blocker that works across all of Apple’s main products — iPhones, iPads, and Macs — and isn’t just limited to the browser.
Filtr is a new tool created and maintained by Kaylee Serena Calderolla, the developer behind the popular Safari browser ad blocker Wipr. Wipr prevents ads from ever appearing in Safari, meaning that the ads won’t load, nor will their tracking code that advertisers use to follow you around the web and snoop on which websites you visit. The result is a cleaner browsing experience, free from advertisers watching over your online activity.
Filtr is an additional paid-for feature bundled into Wipr that goes one step further than ad-blocking in the browser by blocking ads in iPhone, iPad, and Mac apps. Filtr does this by using a new feature embedded in the latest Apple software called URL filters, which lets developers block access to certain websites or domains at the network level, rather than just in the browser.
