Ka-Block! is a content blocker for Safari that prevents ads and tracking scripts from slowing down web pages you visit.
Many sites use third-party scripts to track your behavior across the web, causing pages to load slowly and draining your phone’s battery. Blocking these scripts dramatically improves page load time, data usage, and battery life.

Works as advertised
Mobile ads and their trackers are the worst. I had been using 1Blocker for a while, but quite a few sites would be broken where I couldn’t use menus or searches. Ka-Block has changed that. It blocks most of what I hate while not breaking the way websites work. It doesn’t block everything, but that’s not what it’s designed to do. It’s designed to block what it can without breaking websites, and it does a great job at it.
I also use the desktop version because it’s the only ad blocker I’ve found that doesn’t require access to contacts, your richest relatives’ bank accounts and signing up for all current and future marketing scams. This iOS version does as advertised quickly and efficiently.
Perfect. Use easybib site to cite work for class. It’s a great site for citing research papers but is bombarded w/adds. Info input boxes for citing were constantly moving all over screen due to adds popping up like an unstoppable rebel force causing a lotta frustration as I needed to constantly readjust cursor w/mouse. This app stopped that completely. I’m grateful.
