Who it is for
Built for young athletes and their families.
- Boys and girls aged 7 to 17.
- A recent bone-age X-ray report from a radiologist.
- Height and weight measured at home or by the coach, plus both parents' heights.
Good to know: every child grows in their own way, influenced by genetics, nutrition, sleep and health. That's why your report shows a most likely adult height and a realistic range around it. It's a planning tool for families and coaches, not a medical exam, and it works best alongside your child's regular check-ups with their doctor. If we can't use the information you send, we'll let you know before starting and refund you in full.
