BeTaller: Height Predictor

How much taller will your child grow? BeTaller answers with numbers. We sell no milk and no supplements. FOR PARENTS Enter your child's age, height and weight and both parents' heights. In two minutes you get: • Your child's predicted adult-height range • Where your child stands among Vietnamese children of the same age and sex • What to watch this year, and when a doctor's visit is worth it No bone-age X-ray needed. HOW THE PREDICTION WORKS BeTaller blends three published methods: Khamis-Roche (Pediatrics, 1994), Vietnamese population height data from the NCD Risk Factor Collaboration (The Lancet, 2020) and mid-parental (Tanner) height. Khamis-Roche was built on a Western population and runs high for Vietnamese children, so we limit its weight and anchor the result to Vietnamese data. Every source is listed in the app, linked to the original paper. UNLOCK ONCE, KEEP IT UNTIL THEY ARE GROWN • The exact figure and your child's growth curve to 18 • An age-right sleep, food and exercise plan, 10 minutes a day, built with a registered physiotherapist practising in Canada • A monthly check: is your child still on track? • AI meal scanner: photograph a meal and see what protein, calcium and vitamin D3 are missing, Vietnamese dishes included • Reminders for parents, in Vietnamese and English EACH YEAR OF GROWTH COMES ONCE Once growth plates close, no method lengthens bone. BeTaller helps you make the most of the years your child is still growing: enough sleep, the right food, regular movement, and an early signal when something looks off. TEENS CAN USE IT TOO If your 12 to 18 year old installs it themselves, the app speaks to them in their own voice: a daily Growth Score, a bamboo shoot that grows, 17 badges. They can send their result to you with one tap. VIETNAMESE AND ENGLISH Vietnamese by default, full English, for Vietnamese families everywhere. — Note: BeTaller is not a medical device and does not diagnose, treat, cure or prevent any medical condition.
