Height Predictor AI

Features
Read full description

See where your height is headed — and make every growth year count. HOW IT WORKS 1) Take the 2-minute quiz — age, height, parents' heights, sleep, food. 2) Get your predicted adult height range — the Khamis-Roche method, shown honestly as a range. 3) Start the daily plan for the rest — posture, sleep and nutrition habits, one checklist a day. TallPath predicts your adult height range from the factors that actually matter: your current height, your age, your parents' heights, and how you sleep, eat, and move. The prediction uses the Khamis-Roche method, a peer-reviewed pediatric formula — shown honestly as a range, because genetics set the range and habits decide where you land. YOUR PREDICTION — Current height vs. predicted adult range, updated monthly as you log progress. YOUR DAILY PLAN — A personalized checklist of posture, sleep, and nutrition habits built from your quiz answers. Streaks, a calendar view, and tasks you can complete any time before midnight. TRAIN — A growing library of posture and mobility exercises with guided timers, browsable and repeatable from day one. AI COACH — Ask anything about posture, sleep, nutrition, or your prediction. Your coach knows your plan and answers 24/7. PROGRESS — Log your height, watch the chart move, and get a monthly report comparing prediction to reality. TallPath Premium is available as a weekly or yearly subscription or a one-time lifetime purchase. Subscriptions renew automatically until cancelled at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings.
