Marea helps estimating the area for a region given by a set of coordinates. Useful for plots, farm land, roof measurements and anything you can see with Maps.

The total area is calculated and given in several units, such as square meters, square feet, acres, hectares, square km and square miles.

Also available is the distance between each point.

Available as an In-App Purchase is the ability to save the areas, add notes, attach pictures, calculate a price by multiplying a value with the given area, and share as both an map image or a KML file.

Measurements do not take elevation and other minute aspects into account. This tool does not replace the need for an accurate professional survey.

Ok but only on a larger scale

The GPS is not really accurate enough on the phone to make precise map measurements from a GPS position. You can mark points on a map, but only zoom in up to a certain point so measuring smaller things (like a 1000 sq ft roof) is tricky. For larger scale measurements where the points to mark are clear I could see this being ok, and only as an approximation.

Great free program

Was very curious about the dimension of some land. It worked great with my phone. I am unsure if there is a paid version or if it has more functions, like save or print. It is defiantly worth a try.

I love to use this app, I wish that I could use it on pictures I’ve taken. Also dropping pins are hard to move with accuracy with out a stylus
