Filtr is a new privacy tool that blocks ads in almost every iPhone and Mac app

Filtr has added a new feature that can block ads from loading inside apps on iPhones, iPads, and Macs. The update extends its reach beyond traditional browser blocking to cover many app-based ads as well.

The change reflects a broader shift toward system-level privacy tools that work across apps rather than only in web browsers. If widely adopted, tools like Filtr could put more pressure on mobile ad networks and app publishers that rely on in-app advertising.
