Crew keeps you and your trusted circle a step ahead when you're out for the night, or just around town. Every time you open the app, Crew pulls live crime data from law enforcement agencies across the US, analyzes patterns near your location, and delivers a plain-English AI safety briefing: what's been happening in your area, what to watch for, and how the current risk compares to normal. AI Safety Briefings Get a personalized report for wherever you are; downtown, a new neighborhood, or a city you're visiting. Crew surfaces relevant incident patterns, not a wall of raw data. The briefing updates automatically so you always have a current picture. Live Group Map: Like Slack, add your close friends, or whomever you're going out with tonight, as your Crew and see everyone's real-time location on a shared map. Know that your roommate made it home, track each other at a festival, or just keep tabs on the people you care about. Location sharing is end-to-end, so only your Crew can see you. Launch an SOS flare: One tap sends an instant alert to your current Crew with your name and live location. No cell service required for the alert to queue. It sends the moment connectivity is restored. Privacy First: Crew never sells your data. Your precise location is shared only with the specific people in your group, never stored on our servers as history. Calendar access is read locally on your device and discarded after each briefing. You can revoke all permissions or delete your account at any time. What Makes Crew Different Crime data sourced directly from official city open-data portals, updated automatically 30+ cities covered, with more added regularly, the rest of the country covered with demographic mirroring No subscription required No advertising, no tracking SDKs Works in the background without draining your battery Whether you're going out with your friends, navigating a new city, walking home late, or just want to know your Crew is safe, Crew has you covered. Crime data is sourced from public law enforcement open-data portals. Crew is a situational awareness tool, not a substitute for emergency services. In an emergency, always call 911.
