Yeah, I'm surprised too. Adguard has become my chosen content blocker on iOS. It's fast, removes white space, and blocks ads and trackers effectively. However, what makes it stand out from other content blockers is the dedicated team behind it that responds super quickly to user report. You can check their Github and see how fast they are adjusting their filters and pushing them out to the app:

Try Adguard and you won't be disappointed. I even purchased Adguard license for Mac after having such positive experience with Adguard on iOS (that's free!).
