See how tall you'll be. MaxHeight predicts your adult height in about 60 seconds. Answer a few questions — your height, your parents' heights, where you are in puberty — and get your predicted adult height with its likely range. No photos, no guessing: the prediction blends up to four established pediatric methods, built on CDC growth data. Then do something about it. MaxHeight turns your prediction into a daily plan: • YOUR PREDICTION — predicted adult height, your likely range, and how you compare with people your age right now. • A PLAN FOR EVERY DAY — 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. • EAT FOR GROWTH — daily calorie, protein, calcium and vitamin D targets from official US references (NASEM, USDA). Photograph a meal or describe it in words; foods the app doesn't know are looked up in the USDA reference database, and anything estimated is marked so you can correct it. • ASK THE COACH — a growth coach that answers your questions and can look at a plate of food, your posture, or an exercise position. • COMMUNITY — ask a question, share progress, and hear from people your age. Text only, every post checked, 13 and up. • TRACK IT — log your height as you grow. Your real measurements sharpen the prediction over time. • STAY ON IT — streaks, achievements, and an optional daily reminder. Where our numbers come from: every figure in MaxHeight traces to published science — CDC growth charts, NASEM dietary references, USDA food data, WHO activity guidelines. The methodology screen shows exactly which, so you can check for yourself. No app can predict height exactly — that's why MaxHeight always shows the range. MaxHeight is a subscription.

Verdict
The clearest difference is rating: HeightMax at 5.0 against MaxHeight's 4.4. HeightMax also leads on monetization model (free with in-app purchases vs subscription). MaxHeight's advantage is ratings volume (7 vs 1) and iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. MaxHeight sells 2 in-app purchases, starting at $4.99 per 7 days and HeightMax sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
HeightMax holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: MaxHeight has 7 ratings behind it against 1, so its average is the more settled of the two.
