GPS Field Area Measurement

The app allows you to easily measure distance, area, or just determine the coordinates of a desired point. The first time you run it, it will ask for access to your geodata to download a map of the area you are in. Then you can either highlight the desired section of road or area directly on the map, or turn on your GPS tracker and walk - the app will measure all the distance you've traveled, or the area you've walked around.

Pros:

  • Very easy to use - the interface is intuitive, it takes literally a couple of minutes to figure out all the features.
  • You can select points directly on the map, even without knowing the exact coordinates or just pass the desired distance with the phone in hand.
  • The app relies on accurate data from Google and Yandex maps.

Cons:

  • There are small inconsistencies in the maps caused by problems in the original data. But this can usually be resolved by simply checking the information on another map.
  • Not suitable for measuring small distances - for example, in a room or an apartment.
  • Many features are only available with a paid subscription.
