📝 About this app
Parents, are your kids going to outgrow you?
Kids, are you going to be taller than your parents or your older brothers and sisters?

The percentile ranking shows how the person sizes up to others. For example, a 10-year-old boy who is 4ft 9in is at the 82nd percentile.… View full description on the official store →
