I use Ecosia on my phone because it has a built-in ad blocker that actually works.

I use Revanced instead of YouTube/Music so I don't get ads and can listen to what I want (I had to change my phone's DNS, because on data it wouldn't let me watch or listen to anything that was marked "explicit").

I haven't updated my Discord app in the last couple years because I heard that one of those updates supposedly introduced ads and I said "hell no."
