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.

Thankfully you don't really need an adblocker for apps on an iPhone. Your browser could use one, but thankfully those do exist :)

That said, I want off the iOS ecosystem, but Google has basically said guess what? We are going the way of Apple, so we don't care about you either.

So right now there isn't really anywhere else to go. I'm going to keep trucking in iOS for now, but I hope I find something better soon.
