TallUp: Adult Height Predictor

How tall will I be? How tall will my child be as an adult? TallUp answers with a serious statistical estimate of your adult height in under a minute — then helps you track growth, measurement after measurement.

TRACK YOUR GROWTH. DISCOVER YOUR POTENTIAL.

AN INSTANT, HONEST ESTIMATE
Enter the age, current height and both parents' heights: TallUp computes an adult height range using the target-height method (the adjusted parental average pediatricians use) combined with reference growth curves. About 9 in 10 teenagers reach an adult height within their TallUp range. No X-rays, no bone age — a transparent statistical estimate that is upfront about its limits.

A HEIGHT CALCULATOR THAT GETS SHARPER
Unlike a one-shot height predictor website, TallUp is a height tracker that improves with you: every new measurement refines the prediction, because your own growth trajectory leads the math. The range narrows as you grow — that is the app working exactly as growth science says it should.

GROWTH CHART AND PERCENTILES
See your growth chart with your personal target zone, your growth-curve percentile and your growth speed. Parents get the familiar feel of a child growth tracker and pediatric growth charts; teens finally see where they are heading.

FOR TEENS AND FOR PARENTS
How tall am I going to be — and how tall would I be as an adult? Wondering whether you will still grow at 16, 17 or 18? When do you stop growing? Or are you a parent who wants to track your children's growth over the years? TallUp handles multiple profiles and adapts its wording — a teen growth tracker and a child height predictor in one app.

STILL GROWING?
Growth does not stop at the same age for everyone. TallUp takes your self-declared puberty stage into account: being late is not being out — the growth window is sometimes still open past 18.

100% PRIVATE
Everything stays on your phone. No account, no cloud, no ads, no ad tracking. Body data belongs to the person growing.

WHAT TALLUP IS NOT
TallUp never promises to make you taller — no honest app can. Estimates are statistical, based on growth references and parental heights, and are never a diagnosis. For any concern about growth, talk to a health professional.

WHY TALLUP EXISTS
At 16, TallUp's founder measured 5'0" and his puberty had not started. Nobody could tell him whether his growth was over or simply late. Three years later, he measured 5'10". No food and no training explains those inches — his growth window had opened late, and it was still open. TallUp is the app he wishes he'd had at 16.

PREMIUM
The precise estimated adult height, a range that sharpens with every measurement, the full growth chart, unlimited history, percentiles, the odds of reaching your dream height, daily tips on sleep, nutrition and physical activity, and multiple profiles.
