I'm using this on my Mac as well as on my 6S+. It works great, and it's easy to suspend blocking or use it with custom lists. This is one of the most effective and complete blockers available, and the software creator has not sold out to any advertisers. Pretty much this is a no brainer - after using others for a while, I've been using this on the iPhone for 6 months and now on my Mac. It's the best.
