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.

About

Read full description

Will they be tall like their dad? Most parents guess from pencil lines on a door frame, and the door frame stays behind when you move. Centile works out your child’s most likely adult height and the range around it. It uses both parents’ heights, and from age 4 your child’s own height and weight too. Every number comes from published research, named in the app. WHAT YOU GET • Their likely adult height and range • A growth chart from birth to 20, with every height check kept for good • A monthly height check you do together • How they compare with other children their age • Exercise, food and sleep guidance for teens • One subscription for the whole family At 13, your child can move their record to their own phone and carry on. Food, sleep and exercise help children grow normally. None of them adds height or changes the range. It’s a guide, not medical advice, and it can’t spot a growth problem. If you’re worried about your child’s growth, talk to their doctor. Centile works on one phone. Everything stays on that phone. There’s no account, and nothing syncs to another device. No ads, no tracking. Apple backups may include app data. Centile is a subscription. It renews until cancelled and is managed in your Apple account. Age comparison uses the CDC 2000 US growth reference. CDC does not endorse Centile.
