For Safari, there is https://adguard.com/en/adguard-ios/overview.html

There's also the beta/alpha Orion browser from Kagi: https://apps.apple.com/us/app/orion-browser-by-kagi/id148449..., which has built-in ad blocking

I like 1Blocker. I’ve downloaded it when it was an inexpensive one-time purchase, and was grandfathered when it became subscription-based. Though I believe there remains an option to pay once and keep using it “forever”, now at a slightly higher price.

The app includes both Safari ad blocking and local DNS blocking too, so it works on things like some ads on games.

I wonder this too. The ones I’ve tried so far didn’t work well.

Wipr works well for me.
