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. TallPath Premium is available as a weekly or yearly subscription (yearly includes a free trial) 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.

About

Height Predictor

Features
Read full description

Estimates a child's adult height from the CDC stature-for-age charts plus both parents' heights. Shows a range, the percentile chart with your kid's dot on it, and the math behind the number. Every source is in the app. A Sources & references screen lists the CDC growth charts, the published papers behind the percentile and mid-parental steps, and the guidance behind each daily prompt, each one linked and saying which part of the app it backs. Log height a few times a year to follow the curve. There's a daily habit checklist and guided stretch routines with illustrated demos. Stretching is for posture and mobility; it does not change adult height. Works in cm or ft/in. Runs entirely on your phone. No account, no server, no analytics, no ads. Deleting your data in settings removes it completely. Heightcast is an estimate built from public growth references. It is not a diagnosis, not a medical device, and not a substitute for a pediatrician. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
