Get an honest adult-height range in seconds — the kind that never changes after you pay. HeightPal predicts your child's or teen's adult height from both parents' heights and the current growth percentile (Khamis-Roche), then turns growth tracking into a warm weekly ritual for the whole family. Every other height app made you pay just to see your number. Not here. AN HONEST PREDICTION, SHOWN FREE HeightPal shows the full predicted range up front. We explain how we calculated it — parents' heights, current growth percentile, blended into a projected adult height on WHO and CDC growth curves. The number never changes after payment. No bait, no upsell tricks. A GROWTH CHART THE WHOLE FAMILY CAN SHARE Add every child on your family shelf, then switch between them with one tap. Each child gets a Measured and Projected growth chart on percentile lines, plus a keepsake growth journal — a photo, a height, and a note for every milestone. Watch a year of growth in one scroll. THREE LIGHT DAILY HABITS, NO STREAKS The Today tab prescribes three gentle habits that support growth: an eight-hour sleep window, a nutrition check-in, and three posture stretches (Sky Reach, Side Lengthener, Posture Lift). About two minutes total. Do them any time. No streaks, no pressure. A WEEKLY MEASUREMENT RITUAL A quiet Sunday nudge — one gentle reminder to re-measure. That's it. No notification spam. Log a new height and the chart updates, the prediction re-projects, and your journal grows another entry. HONEST, TRANSPARENT BILLING Renewal date visible on the paywall. One tap to your store settings to cancel. Restore purchases in one place. No auto-renew traps, no dark patterns. Your free prediction and growth chart stay yours. FOR PARENTS TRACKING KIDS AND TEENS TRACKING THEMSELVES HeightPal works for the whole family — a toddler's first measurement, a teen preparing for a growth spurt, or a parent building a growth keepsake to look back on. Sex-specific WHO growth curves for boys and girls. HEIGHTPAL PREMIUM Unlocks full unlimited history, unlimited family profiles, unlimited journal milestones with photos, a deeper stretch library (Morning Posture Flow, Evening Wind-Down, Growth Mobility), and monthly re-prediction updates. Weekly, annual, and lifetime plans. 3-day trial with no auto-charge unless you confirm. HeightPal does not provide medical advice. All suggestions are based on common growth-promoting practices. Please consult a healthcare professional for personalized guidance. Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period.

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. Restore previous purchases from the paywall. TallPath is not a medical device and does not provide medical advice. Predictions are statistical estimates, not guarantees. Consult a doctor about any concerns regarding growth or development. Privacy: https://tallpath.app/privacy · Terms: standard Apple EULA
