GrowMax: Height Predictor

GrowMax is a height predictor and height calculator for teens, with daily stretches, sleep and food habits that support healthy growth.

How tall will you be? GrowMax estimates your adult height using CDC growth data, your family's heights and a quick puberty check — then gives you a daily plan of habits that support healthy growth.

IMPORTANT
GrowMax provides estimates for informational and motivational purposes only. It is not a medical device and does not give medical advice, diagnosis or treatment. Final height depends mostly on genetics; habits can help you reach your natural potential but cannot guarantee extra height. Talk to a doctor or healthcare provider about any growth concerns.
