It is possible with SNI blocking to adblock on Android, even when apps use custom DNS revolvers (though not as effective). I built https://github.com/jawline/Puffer a while ago but haven't had the time to improve it much past proof of concept.

Heh, Google adding ad blockers.... I think you might be on the wrong timeline.

i use this on ios: https://apps.apple.com/app/apple-store/id691121579?pt=425087...

it’s a vpn profile that just intercepts dns requests locally and screens with a hosts file

Pihole works well here but obviously not end user friendly.
