After School is an iOS and Android social network mobile application that allows users in a defined network, currently high schools, to share anonymous text-based posts and images with others. As of July 2016, After School had users at more than 20,000 american high schools. According to CEO Michael Callahan, the app was created as a network “that teens could use to express themselves, to reach out to others and to ask for and offer help to fellow teens in distress.”
