How it works
Four steps, and the first one is free.
Answer 14 questions
Your age, height, and your parents' heights. About 60 seconds, no account needed.
Get your prediction
Your predicted adult height with the likely range around it, and where you sit today.
Follow the daily plan
Sleep, food and a session each day — a full year, planned out and progressing.
Log and watch it sharpen
Your own measured growth rate replaces the estimate, so the prediction improves as you go.
Every number
has a source
Growth apps are full of numbers nobody will stand behind. Every figure MaxHeight shows you traces to a named, public source — and the app tells you which one, in plain language, on a screen you can read any time.
Your calorie target comes from the current national reference intakes. Your week follows the official activity guidelines for your age. Every food value traces to USDA data. Nothing here is a number we made up.
MaxHeight is not affiliated with or endorsed by any of these organisations. It is not a medical service.
