My team (cofounder Jamie McCrindle to be precise) built a free ad- and tracker-blocking app for iOS 9+, that is available in the Apple App Store here. We ran it through the same tests we’ve done for 200+ other blockers, and it turns out to be one of the best.
We hope you’ll use it in conjunction with our subscription service, but you don’t have to. It’s totally free, so give it a try. Remember, that you’ll need to be running iOS 9 or newer, and it works in the Safari browser only.
Did I mention that it’s FREE? Try it here.
