WatchOverMe is a mobile watchdog app founded by Xin Chi, which was launched in 2012 with the goal of protecting users from danger. The app initially served as a personal bodyguard, alerting family and friends when a user was in danger, but now focuses on a more proactive approach to prevent potential dangers through video recording and data mining. With over 140,000 users, WatchOverMe has become a popular app that uses Twilio SMS to send alerts and track locations via GPS. The app's expansion into proactive safety features, such as alerting users of areas they should avoid, is based on data scraping from crime reports, statistics, and social media hashtags, with the goal of empowering users to take control of their personal safety.
