AIS Radar

1. Download and open the app, then allow location permissions so your position and nearby AIS targets can be displayed. 2. Choose your map view and range rings, center on your GPS position, or pan to a marina or coastal area of interest. 3. Tap any vessel target to see name, MMSI, course, speed, destination, and distance; use the search bar to find a specific ship or port. 4. Set alerts by defining a safety radius or CPA threshold, and enable filters to show only selected vessel types or sizes. 5. Save favorite vessels and custom zones for quick access, and optionally connect a compatible AIS receiver to extend reception range. 6. Adjust units, night mode, and data refresh rate in Settings to match your cruising or harbor-monitoring needs.
