Field Distance Measure 3D Map is a free iPhone application designed for Travel & Navigation purposes. The app offers a Distance Tool that enables users to swiftly calculate distances between points on a map. It also allows for area calculations of non-overlapping polygons drawn on the map. Users can opt for metric (meters, kilometers) or imperial units (yards, miles, feet for altitude) for distance measurements. Co-ordinates can be displayed in decimal or degrees, meters, and seconds.

This app is particularly useful for mapping fields in agriculture, defining land or home boundaries, or simply exploring distances and areas. Additionally, users can access standard map views such as standard, satellite, and hybrid. The app supports quick altitude calculations even without data connectivity, providing information on altitude for any given point.
