You put in your height age sex weight. It tells you your bmi and the percentiel your in related to others your age and sex.
If your height bmi is 25% then 25% of the people your age are shorter and 75% are taller. Same with weight. (I wish my height was 25%, it told me 2%. Im short, 4'11) :P
Hope that helped!
