The third major change involved reaching out to public safety experts, police, and civil rights leaders — among others — to get input on how to make this app safe for people to use.
For now, Citizen is only available in New York City — Frame said the company wants to prove the concept in New York first before taking it elsewhere.
"We do have demand to come to many cities across the country already and we do have that on the roadmap," Frame said. But this will take time, he said, since Citizen does require physical infrastructure and set up in each individual city.
When you log on to Citizen, you'll be able to see a real-time map of incidents in your area. Each red dot represents a separate incident.
The "Recent" tab shows events chronologically, but the "Trending" tab opens up live events.
The crimes listed in Citizen are sourced from 911 calls. Things like false alarms, gas leaks, commercial burglary, minor car accidents, or suspicious bags will not appear on the app.
"We have a criteria as to what goes into the app and what does not go into the app," Frame said. "Our first focus is safety — user safety, officer safety — and our criteria is completely based on safety."
Citizen is available for free in the App Store and the Google Play store.
