Citizen
Citizen is a free mobile application that notifies its users with safety alerts and real-time incident updates. Emergency services and community activists alike hail the app as a ground-breaking development in personal and community safety. It is a powerful force for good that has evacuated people from burning buildings, diverted school buses from nearby terrorist attacks, and in many instances has helped reunite missing persons and pets with their families. Citizen provides you with alerts sourced from the latest 911 data. The alerts are accompanied by live stories, real-time updates, and user-generated content to provide you with the information you need so you know what’s happening around you rather than having to wonder why police are on your corner or there are helicopters above you. Today, millions of people across the United States have downloaded the app and use it to keep themselves, their families, and their friends safe. The app operates across a growing list of US markets, including significant user bases in NYC, SF, Los Angeles, Chicago, and more metro areas.
