It's a good ad blocker. I've used three in the last year. Wipr 2, uBlock Lite, and Adguard Pro. Only Wipr 2 blocks YouTube and IMDb (site, not app) videos for me.

Wipr 2 and Adguard Pro are paid, though, and uBlock Lite is free (and from the same guy who makes uBlock Origin for Firefox).

Wipr 2 is also made by one solo developer, so she (IIRC) deserves it. It's not like you're throwing dollars at a faceless corp that doesn't care, you're buying a solo developer's next cup of coffee (or half her lunch, maybe). Someone who probably places the same value on those dollars that you do. And that matters to me.
