Ever try to close an ad on your phone, only to wind up clicking on it and going to a sketchy-looking website that definitely seems like it just gave you a virus? 1Blocker uses iOS content blocking features to help you determine what ads and other content you want to block when you’re surfing the web. You can also select certain pages where you always want to see all the content, for your favorite sites. Say good-bye to auto-played videos when you’re just trying to read the news.
