Does anyone know if this app measures the "levelness" of the hips? I was on a K-vest for the first time today. Thankfully, a lot was good, but I do have some funky lower body movements. My right leg straightens, which raises my right hip as compare to my left. My "homework" is to work on trying to turn the hips more level, keeping the left hip higher than it was before. I always over-do things and some objective data as to what I am doing on this would be very helpful as I don't see a K-vest purchase anytime soon. Thanks for any responses.
