Rebrand as Citizen

With New York City as its first test market, sp0n relaunched the app in March 2017 as Citizen for iOS and Android. The app increased its safety messaging to discourage users from approaching or interfering with crime scenes. While developing the new iteration, the company had consulted New York city officials, police, public safety experts, and "civil rights leaders—among others" on making it safe to use. Citizen only sent alerts deemed a threat to "public safety," omitting calls about suspicious people, suspicious bags, and drug incidents. According to the company at the time, "there are about 10,000 911 calls per day in New York City. We include 300–400 on average." Citizen received a hostile reaction from critics. They noted that the

User content

To "ensure there are no graphic images," Citizen's moderators review all uploaded photos and videos, filtering graphic images and comments that are derogatory, racist, or explicit." For users close to an incident, a "record" button appears on screen to allow live-streaming. Users are not paid for videos, "nor are videos gamified with rankings or 'likes'."
