There are several that plug into Safari, and Pihole just works. Does Android have ad blockers that do more? It's been a few years since I switched.
Blokada, Rethink, and Adguard just to name a few. Also, the DNS can be set to NextDNS, both via the system settings _and_ the aforementioned apps.
I can run proper uBlock Origin in Firefox on Android. Sure something like Pihole works, but I am often on mobile data or other WiFi networks.
