Who should use it: Those with manners. The Grade holds its users accountable for their activity -- and kicks undesirables out. Think of it like Tinder meets Lulu (the dating rolodex app that lets women grade a man's desirability for others' benefit). "A" through "F" scores are based on profile quality, response rate and tone of messages. (They've had 20,000 downloads to date and already kicked off 500 users.)
