GeoMeasurement

Distance & Area Calculator lets you tap points on a map to measure distances and areas with precision. In distance mode the app sums each segment using the Haversine formula and shows the total path length in kilometers, meters, miles, or feet. Switch to area mode to drop three or more points and get an instant polygon area in square kilometers, hectares, square miles, or acres, along with the full perimeter.

A compact result card keeps the key numbers in view — total distance or area, point count, last segment length, and bearing — so you never lose track of what you are measuring.

Key features:
- Tap the map or enter latitude/longitude coordinates manually
- Distance and area modes with metric or imperial units
- Edit, delete, undo, and locate individual points
- Save named measurements and reload the full point set anytime
- Export or share your measurement as a standard GeoJSON file
- Automatic draft saving so nothing is lost when you close the app
