The Hottest App Right Now? One Where Teens Have to Say Nice Things About Each Other

TBH was hot. Five years ago, the app, which prompted teens to compliment one another, topped Apple’s App Store charts and quickly amassed millions of users in the coveted high-school demographic. Facebook snapped it up less than three months after launch—and soon shut it down.
