I started using an extension for Safari on my iMac a while back called Ghostery. It basically blocks tracking cookies and other obnoxious little things. It’s not an ad blocker, but it not only speeds up website load times, it’ll protect your privacy as well. It’s awesome, and I recommend you get Ghostery for the Mac right away.

Flash forward to yesterday when I finally got around to trying some content blockers for iOS9 on my iPhone 6Plus. I tried several, including one that was more than the price of a cup of coffee. Let me tell you that almost every single one of them available on the App Store absolutely sucks. Then I came across a Tweet about yet another content blocker—but this one caught my eye because it also mentioned Ghostery.

Peace content blocker for iOSTurns out, Marco Arment (creator of Instapaper and Overcast) has an iOS 9 content blocker called Peace for only $2.99.

What got me to buy it immediately was that A) The screenshots looked much more polished and easier to use than the other apps. And B) Marco has an exclusive deal with Ghostery to use their database as the foundation for Peace’s ability to block trackers. And really, that’s what sold me.

What it does

Peace blocks ads, trackers, social media buttons and other mobile web annoyances. You can configure with a simple slider if you want those social media buttons blocked, as well as most web comment systems and a site’s use of web fonts. All of those things can really slow a web page down, something I can overlook on an uber-fast desktop cable connection but is absolutely infuriating on mobile. As a bonus, Peace can install a set of Share Sheet extensions that allow further access to the app’s capabilities.

Peace isn’t perfect, by any means. Some ads still get through. And sometimes it’ll block things you don’t want blocked. But peace will allow you to add domains to a whitelist if they don’t work properly, or you simply love a site and want to support it by not blocking anything.

Want proof it’s working?

If you buy it and really want to see what it does, may I recommend you visit MacDailyNews before and after installing. At any given time, the site can have around 25 banner ads and a list of trackers as long as my arm. The page loads slow even on a fast cable connection, but on mobile it’s excruciatingly slow. So much so that I often just skip right over any link that points to the site. After I installed Peace, I went to the MacDailyNews homepage. I was shocked when it loaded almost instantly. Of course, almost every one of the ads and all the trackers were blocked, and that’s why it loaded so quickly.

UPDATE: Marco Arment (the developer) has pulled his app from the App Store after having some regrets. If you managed to buy Peace before it was removed, you can request a refund, or continue to use the app until such time that Apple updates iOS to the point that the app no longer works.
