Yes. I used to use Wipr 1 and also found it underwhelming, eventually settling on 1Blocker. Eventually I decided to give Wipr 2 a shot and it’s much improved.
It also now allows blocking even outside of Safari. Though that requires iOS/macOS 26, which I have no intention of installing any time soon, so can’t speak for how effective that is.
I've been using Wipr for a long time. Both on iOS and macOS and it works perfectly. I don't see any ads. When I happen to use or see other people's devices I'm amazed by the amount of ads on the screen.
Edit: at least compared to full uBlock Origin on desktop Firefox. No idea how good or bad are the other mobile solutions.
Most of the time i solve my mobile ad blocking needs by ... not browsing on mobile.
