I can actually see what you mean and agree with you. I remember some driving law...something about not obstructing a driver's field of vision (which is why it's technically illegal to drive with a handicap placard or even a little tree fresher hanging off your rearview mirror). It'll really come down to officer judgment, since they can also view it as hands free (like a Bluetooth). In regards to this app though, it doesn't appear to serve any function while driving, so I can't imagine it being used during driving.
