This app calculates the area and distance based on the latitude and longitude obtained from GPS.
When you want to find out the area, walk around the perimeter on site and mark when you come to a corner.
When you reach the final corner, calculate the area enclosed by the marker.
It can be used to measure the area of land, buildings, etc., and the distance of routes, walking, golf, etc.

Basic usage

1. Press the "Mark at current location" button to add a marker at your current location.
2. Every time you add a marker, a line is drawn and the distance is displayed.
3. Click the "Calculate area" button to display the area surrounded by markers.
The distance at this time will be the perimeter of the selected area.

*Area is not displayed correctly in areas where lines intersect.
