Auto-avoidance engine
Optional: paste a free key for stronger avoidance
Avoidance works with no key — the app detects where the route enters a zone and searches for detour
waypoints that get around it. That search is a good approximation but it tries a limited number of options.
With a free OpenRouteService key
(2 minutes, no credit card) the avoidance is computed inside the routing engine itself, which is
exact — it will never cross a zone if any legal route exists.

How the zones are chosen. They come from published city-level violent-crime statistics (FBI UCR and standard rankings), not live data. Crime varies enormously street-to-street, interstates through these cities are heavily traveled every day, and avoiding an area can add real driving time. This is a personal planning aid, not a safety guarantee or a judgment about the people who live there. Verify routes yourself before relying on them.
