TallUp
Height Predictor & Growth Tracker for Teens and Parents
How tall will I be? TallUp gives a serious statistical estimate of your adult height in under a minute, then helps you track growth, measurement after measurement.
One honest estimate, a growth chart that improves with you, and daily habits that never overpromise.
Age, current height, both parents' heights — TallUp computes an adult-height range with the target-height method combined with reference growth curves. About 9 in 10 teenagers land inside their TallUp range.
Unlike a one-shot calculator, TallUp improves with you: every new measurement refines the prediction, because your own growth trajectory leads the math.
A teen tracking themselves, or a parent following several kids: TallUp handles multiple profiles and adapts its wording to who it's talking to.
Growth doesn't stop at the same age for everyone. TallUp takes a self-declared puberty stage into account — being late is not being out.
Sleep, nutrition, stretching and a daily journal — general wellbeing support, never sold as a way to add centimetres.
Everything stays on your phone by default — no account, no cloud, no tracking, no ads. Body data belongs to the person growing.
Your estimate, your curve, your daily habits — all in one place.
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.
TallUp estimates your adult height from your age, current height and both parents' heights, using the target-height method combined with reference growth curves. It's a statistical estimate, not a diagnosis, and it gets more precise every time you log a new measurement.
About 9 in 10 teenagers reach an adult height inside their TallUp range. The estimate combines the mid-parental (target-height) method with population growth curves, and narrows further once you add your puberty stage or new measurements.
It varies a lot from person to person and depends on puberty timing, not just age. TallUp accounts for a self-declared puberty stage: being a late bloomer doesn't mean growth is over — the growth window is sometimes still open past 18.
