BeTaller

BeTaller helps you understand your height potential and build the daily habits that get you there. A BeTaller Premium subscription is required to view your full prediction and training plan. HOW THE PREDICTION ACTUALLY WORKS Answer a few questions about your age, your and your parents' heights, growth phase and lifestyle. BeTaller blends three published methods: • Khamis-Roche (Pediatrics, 1994) — estimates adult height without a bone-age X-ray • Vietnamese population height data from the NCD Risk Factor Collaboration (The Lancet, 2020) • Mid-parental (Tanner) height Khamis-Roche was built on a Western population and runs high for Vietnamese users, so we deliberately limit how much it counts and anchor the result to Vietnamese data instead. Every source is listed in the app under Sources, linked to the original paper. A DAILY GROWTH SCORE Sleep, nutrition and exercise combine into one 0–100 score, so everything you do today shows up immediately. AI MEAL SCANNER Photograph or describe your meal. BeTaller estimates calories, protein, calcium and vitamin D3 — it understands Vietnamese dishes like pho, com tam and bun bo — then suggests what to add for stronger bones. A TRAINING PLAN BUILT WITH A PHYSIOTHERAPIST A four-level, 12-week program of stretching, posture, bar-hang and core work, developed with a registered physiotherapist practising in Canada. All 41 exercises include setup, step-by-step instructions, breathing, the mistakes to avoid and safety notes. TRACK YOUR PROGRESS Log sleep nightly, measure height regularly, and watch your prediction confidence rise as you add data. YOUR BAMBOO COMPANION Finish your daily routine and your bamboo shoot grows a segment. 17 badges to unlock. VIETNAMESE AND ENGLISH Vietnamese by default, full English support — built for Vietnamese people everywhere. — Note: BeTaller is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. It does not replace professional medical advice. Predictions are statistical estimates, not promises about your height. Once growth plates close, no method lengthens bone — BeTaller focuses on making the most of your growth years and improving posture. BeTaller Premium is required to view your prediction and plan.
