You left the car and went into the woods to pick mushrooms with berries, spun and forgotten which way to go.
Fortunately, you have not lost your Android phone that never forgets anything, and you remember you have a new application. With this application, you click where you left your vehicle or the point where you want to go out, Android uses the location of the sensor recording GPS coordinates and address. Later, when you reopen the app, it shows you a map, which you must remember mesto-- problem is solved!
