Witness, the live-streaming app that serves as a panic button for the mobile age, debuted earlier this year at the TechCrunch Disrupt NY 2015 Hackathon, where it eventually went on to win the grand prize. Now the app is live in the App Store for the public to try, allowing users to broadcast their location, audio and video to a pre-defined set of emergency contacts. – Sarah Perez, TechCrunch
