Only allows women to charge for the date, not men.

"Ohlala is an app for any woman who thinks she ought to be compensated for her time and efforts when she goes out with someone. It seeks to turn leisure time — a precious, dwindling commodity — into billable hours."

But the women users are complaining that the men are thinking they are escorts! ☺️
