I'm sure we've all heard of the app dollify. You can create family and friends as animated dolls (my bff made the one on the top for me). But personally I think it is over rated. If you have popjam then you'll see that many , many people have dollify profile pictures. And on Skype a majority of my friends have dollify profile pictures too. It is a fun app but you can't spend all your time on it.
That's all I have but tell me if you want more app reviews
