Lulu is an Android and iPhone app for women to review men. You can go on the app — that calls itself a "database of men" — to see whether that guy you're into is the real deal or a sleazeball. Even though you're encouraged to log in via Facebook, the reviews are anonymous. You can rate the guys numerically in a variety of categories like humor, appearance, and manners, as well as choose from serious and silly hashtags provided, like #AlwaysPays, #RespectsWomen, #Boring, and #WearsEdHardy.
