Read full descriptionHide full description
See where your height is headed โ and make every growth year count. HOW IT WORKS 1) Take the 2-minute quiz โ age, height, parents' heights, sleep, food. 2) Get your predicted adult height range โ the Khamis-Roche method, shown honestly as a range. 3) Start the daily plan for the rest โ 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 โ shown honestly as a range, because genetics set the range and habits decide where you land. YOUR PREDICTION โ Current height vs. predicted adult range, updated monthly as you log progress. YOUR DAILY PLAN โ 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 โ A growing library of posture and mobility exercises with guided timers, browsable and repeatable from day one. AI COACH โ Ask anything about posture, sleep, nutrition, or your prediction. Your coach knows your plan and answers 24/7. PROGRESS โ Log your height, watch the chart move, and get a monthly report comparing prediction to reality.

MaxHeight turns your prediction into a daily plan: โข YOUR PREDICTION โ predicted adult height, your likely range, and how you compare with people your age right now. โข A PLAN FOR EVERY DAY โ a 365-day exercise plan that follows the WHO and US physical-activity guidelines for teens: impact and strength on build days, mobility and posture in between. Every move is illustrated. โข EAT FOR GROWTH โ daily calorie, protein and calcium targets from official US references (NASEM, USDA).
