A provocative dating app designed to let women anonymously ask or warn each other about men they'd encountered rocketed to the top spot on the U.S. Apple App Store last week.

Tea, a dating safety app which allows women to anonymously give men red or green "flags," says it had more than 70,000 photos stolen in a data breach.
