Alexandra Chong is co-founder and CEO of LuLu, an app that lets women rate men. LuLu Lulu is an app headquartered in London that's getting men riled up.

On it, women are rating the men they know and giving them scores. There's nothing the men can do to keep from getting rated (although Lulu deletes any pre-loaded profile at a man's request).

How does it work?

Since guys aren't allowed in, we thought we'd bring the app to you. You're welcome.
