Ka-Blocking brilliant!

Dose what it’s supposed to do and dosnt use or collect any of you data. Used this app for years, and it being free is an extra bonus. Thank you for your great work and app developers ☝🏻

Free - but minimal

Blocks the basic ads on some websites, but ultimately doesn’t do much. A few tests put it at about 30% effectiveness, hence two stars.

Ad guard better

Website said this blocks adds on not only safari but other apps to, but it doesn’t do that. Ad guard is better so don’t waste time on this 😐

Не работает

Вообще не работает, стало только хуже, теперь при просмотре фильмов/ сериалов, страница перезагружается и включается реклама. При просмотре 25 минутной серии теперь 3 рекламы вместо одной
