Citizen users can view incidents in New York City, Baltimore, Philadelphia, Los Angeles, and the San Francisco Bay Area. When you open Citizen, it will automatically show you the service area you are currently located in. If you are outside a service area, Citizen will default to showing you the last city you viewed.
To switch between cities, tap on the small shield icon on the top left corner of the home screen. In the Places tab, scroll down to Explore Available Cities and select the city you would like to view.
Remember, you can only sign up for Citizen while physically located within a current service area. Once signed up, you can view any Citizen service area from any location.
