wire frame and concept

My concept is to design a smartphone app, which acts as a navigator and calorie counter at the same time. The target audience will most likely be aimed towards a female audience, but not strictly. The idea is that as you are trying to find your way to your destination, the navigator will calculate how many calores the user has burned off, based on the time and distance travelled. What make this app innovative in terms of navigation, is that your camer on your smartphone is activated, thus, the user will be following bold arrows from the view of their camera. This way the user will be able to navigate from exactly where they are facing from and wont have to constantly look around to try and figure out whether they're on the matching street, like you wod on street view.
