In 2018, Facebook proposed an app named Bell aimed at high school students to create a safe space for communication about school events and social interactions. Internal documents indicated that Facebook intended for Bell to engage teens and transition them to the main platform after graduation. The app was designed to include features like group chats, event organization, and an anonymous confessions section. Facebook aimed for Bell to reach 80% of U.S. high schools by the end of 2020, with plans to expand globally. However, the app was never developed, and a spokesperson described it as an early exploratory idea dependent on strong content moderation. Meta has faced legal challenges regarding the impact of its platforms on minors' mental health and has implemented features in its Teen Accounts to empower parental control.
