pavsoss/Safera-App — reverse-engineered prompt

Build me the Safera mobile app, a safety first navigation app for people walking or commuting alone.

I want users to sign up or log in with a “Shield” style account, save emergency contacts, enter a starting point and destination, then see three route choices with clear colors, safest, balanced or main roads, and shortest or higher risk. Each route should show a live safety score based on crime risk, street lighting, crowd level, time of day, and nearby safety reports.

Add a map view with GPS, navigation, a visited path trail, and simple warnings when the user gets near a risky area. Users should be able to tap the map to report things like dark zones, isolation, or crime concerns so future routes can use those reports.

Also include an SOS mode that shares live location with emergency contacts using the tracker backend, plus a profile screen where users can update details or delete their account. Use the existing mock safety data and route scoring logic, and look up current Expo or maps docs online if needed.
