Point your phone at the sky. Every plane gets a tag with its flight, route and height.
Uses your location, compass and camera. Nothing leaves your phone except a rounded location to fetch nearby aircraft.
Type a suburb or town and pick it from the list.
Suburb search by OpenStreetMap Nominatim.
If tags sit beside the planes instead of on them, nudge these while looking at a plane or the sun.
Positions come from volunteers’ receivers and can lag or miss aircraft. Not for navigation.
