Heightly

Find out how tall you could get. Answer a few questions, get your height forecast, then follow a daily plan that makes the most of your growth window.

How tall will you be? Heightly turns that question into a plan.

Answer a short quiz about your age, family height and lifestyle, and Heightly builds your personal height forecast using the same methods clinicians use: growth-chart data and the classic mid-parental formula, sharpened by your growth-stage signals. Then it gives you a daily program to make the most of the height that's still in your hands.

YOUR FORECAST • A personal projected height that sharpens every week you track • See your percentile, your peak potential, and the odds of hitting your goal • Weekly height check-ins keep your prediction honest

YOUR DAILY PLAN • Guided stretching and posture routines with a built-in timer • Daily goals for sleep, nutrition and training, with streaks that keep you showing up • Add your own custom goals

AI MEAL SCANNER Snap a photo of any meal (or just describe it) and get an instant Growth Score with the protein, calcium and vitamin D that matter for growing bodies, plus one concrete way to make the meal better.

AI GROWTH COACH Questions at 11pm about sleep, food or training? Your coach answers around the clock, personalised to your profile.

SLEEP & NUTRITION TRACKING Log your nights and meals in seconds and watch your weekly analysis connect the dots between your habits and your growth.

BUILT ON REAL RESEARCH Heightly's guidance draws on peer-reviewed studies on sleep, activity and nutrition in growing teens, and every study we cite in the app links to the original source so you can read it yourself.

AN HONEST NOTE Genetics set most of your height. No app can promise extra centimetres, and anyone who does is guessing. What Heightly does is help you sleep, eat, move and stand like someone who reaches the top of their own range.
