The food logging is great (although some obvious inaccuracies in the rating system). The fun facts and science are also interesting, plus I love the sense of humor on the app. I find the group messaging to be not as useful - too many people making comments on lots of different things. Possibly, they could streamline that by only allowing the group leader to start a thread. And my personal coach has not really done much in terms of coaching, although she sent me a great article about mindful eating yesterday.
Bottom Line: Yes, I would recommend this to a friend
