TECH CRUNCH - A new social app, Locket, popped to the top of the App Store. Locket's clever premise puts live photos on friends' iOS home screens in a widget. The app launched on New Year's Day and has seen ~2M users sign up. Matt Moss, the founder of Locket, credits its rapid adoption to going viral on TikTok. He published videos to an accompanying company account for Locket to show the app in action.
