I'm just sharing here this app I use always on my phone, and I don't see many people talking about it.

It's similar to DuckDuckGo app feature that block trackers across all the device, but this one is focused only on that, it also allows you to add your custom tracker URLs to block and monitor every request being made.

It's open source and available on F-Droid: https://f-droid.org/packages/dev.clombardo.dnsnet/
GitHub: https://github.com/t895/DNSNet

It enables a VPN to intercept requests, so it can block URLs of trackers across all your apps. The app provides a list of URLs as you open it for the first time, you can choose a few options between less or more aggressive.

Obs.: The app don't tell, but when you add a custom URL you need to disable and enable it again.
