A new mobile app allows women to rate their former partner's humour, appearance, manners, ambition and commitment, on a scale of one to 10.
On Lulu, women are able to give rating to past hookups and ex-boyfriends.
Alison Schwartz and Alexandra Chong got the idea for Lulu after a girls' brunch resulted in them oversharing about Topshop sales, dermatologist appointments, and, eventually, guys, the New York Daily News reported.
The app, exclusive to women, was launched in January and has been placed consistently among the top 20 in the iTunes store.
The app syncs to users' Facebook accounts to scan pals and see which men have been rated.
