Chess with "Friends" v. Chess.com iPhone app

I've been playing Chess with Friends on my iPhone. I don't like it. The games are not rated, and neither are the players. You have no idea if your opponent is a beginner or experienced. Most likely, the player is a beginner. I've been using the app for over a month and I haven't played a challenging game yet. But, I do really like their interface. In fact, I wish the Chess.com app was designed more like Chess with Friends. My biggest problem with the Chess.com app is that it keeps freezing up on me. When it freezes, I have to restart my phone to get it working again. And, aside from that problem, Chess with Friends has a way better chat function than Chess.com's app. I love using the Chess.com app but, it needs some work.
