I use Firefox Focus, which includes an ad blocker that can be enabled for Safari integration.

It works pretty well for me, but then, I don't generally surf on my phone and only use Safari when I have clicked a link from messages or something.

I'm interested in other possible options on iOS as well, though. Hoping to see more replies.

AdGuard provides DNS servers that allow you to filter for the whole device, regardless of device type or which app you use.

Configure your home router to use it to filter for every device on your home WiFi network.

They have one set of DNS servers that just blocks ads and another set that additionally attempts to filter out adult content.

AdGuard is pretty nice, you can also use other browsers like Firefox focus’ add blocker by installing them then turning it on in the extensions section of the safari settings.

I use AdGuard. There free version is more than enough to block ads including YouTube ads.

For Safari on my Mac I use the Ka-boom extension

Hyperweb is very nice. They even redirect Reddit links to Teddit so you can avoid their dark patterns.

Firefox Focus is free, but I use Wipr on both iOS and macOS.
