Ask HN: Best DNS Blocker for iOS

Looking at fairly simple, idiot available, DNS block options for iOS -- by idiot i mean downloading an app and making some basic changes myself, not trying to run a pihole through my own server, etc.

-- My only real requirement would be that i could be allowed to be add my own domains that i want filtered to my own black list (such as iOS ads domain so i no longer have to see ads in News+ app).

I've been using Adguard Pro but the latest version for some reason refuses to transmit any data while on cellular network, it works fine on wifi but on cellular i get nothing. i tried searching forums but even though people list these problems about once a year since 2017 there doesn't seem to be ever a viable solution posted.

i then switched to NextDNS, but that DNS doesn't allow me to add additional domain.

i also switched DNSCloak but it also doesn't have a selection to block your own domains (or maybe i just need to pay the $12 updated pro version?).

So anyways, could someone advise an DNS blocking app that they use on iOS that perhaps isn't AdGuard that would help me do what i want to do?

Tnx.
