No guessing. Just clear answers based on real data. Enter your age, current height, and your parents' heights. InchUp runs the mid-parental height formula and Tanner stage growth model — the same methods used in pediatric medicine — and shows you your estimated adult height and where you are on your growth curve. Then point your camera and measure your height instantly. AR body detection gives you your current height in under 3 seconds, accurate to ±0.5 cm, with no equipment needed.

Spot growth spurts before they happen. Nutrition plan for growth Daily meals across Breakfast, Lunch, and Dinner built around calcium, vitamin D, protein, and zinc — the key nutrients that support bone development and healthy growth during teen years. Daily exercise routine Beginner-friendly exercises for posture improvement and spinal decompression. Includes bar hanging, cobra stretch, and pelvic shift — moves recommended for growing teens and young adults. BUILT ON REAL SCIENCE InchUp predictions use the same growth data trusted by paediatricians worldwide.

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.

Verdict
The clearest difference is rating: HeightPal at 5.0 against InchUp's 1.0. HeightPal also leads on update cadence (fortnightly vs every 3 months) and ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. InchUp sells 2 in-app purchases, starting at $6.99 per 7 days and HeightPal sells 5 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
HeightPal holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: HeightPal has 6 ratings behind it against 1, so its average is the more settled of the two.
InchUp ships an update every 3 months, HeightPal fortnightly. The most recent releases landed on October 28, 2026 and October 31, 2026 respectively.
