At the moment, Citizen is only available in New York City and the San Francisco Bay Area. The Citizen app requires significant infrastructure and resources to operate in a given location, which is why our coverage is currently limited. We're working hard to expand our coverage in the future, so stay tuned for updates!
In the meantime, please fill out this link to let us know where you'd like Citizen to come next: https://www.citizen.com/#request-form
