Lulu
This rating app is a fun way to exchange and inform yourself about people you are interested in. Lulu gives you the opportunity to rate a friend, a hook up, or even your ex-boyfriend, based on a series of questions about your experiences with the person. Then, the app creates a number based on your responses, which is open for the world to see! Lulu users can rank any of their Facebook friends, which can be a great way to learn about your next date's reputation.
