The smartwatch is a good companion of the Endomondo app to keep track of her jogging route. You can start the application, see its evolution, pause easily and simultaneously change tracks and change the volume of the music player. As against a star less for the clarity of the screen not really readable outdoors.
Otherwise outside outdoor sports (walking, jogging, trail, cycling) to accompany a tracking application I do not really see the object of interest (geek or die?); except perhaps to avoid out of pocket a smartphone 500 and in transport.
