It does what it says. It calculates the BMI based on height, thats it. It is a tool one can use to measure progress if you are losing or gaining. If youre 52" and 85 lbs dont argue with an app, talk to your doctor about why youre underweight. If youre not happy that your result is overweight or obese, again, consult your doctor. An app is no substitute for the qualified medical advice of a doctor.
