Your weight, height and saved measurements stay on your phone and are never sent anywhere. Works offline. HOW IT WORKS BMI = weight in kilograms divided by height in metres squared. Categories follow the World Health Organization adult classification: below 18.5 underweight, 18.5 to 24.9 normal, 25 to 29.9 overweight, 30 and over obese. Sources: WHO and CDC. IMPORTANT BMI is a screening number, not a diagnosis. It does not measure body fat, muscle, age, sex or fitness. For adults 20 and over only: children and teens are judged with BMI-for-age percentiles. Talk to a doctor or dietitian before starting a diet or exercise plan and before making any medical decision.
