Height Predictor - TallTell

Ever wonder how tall you'll actually be?

TallTell uses science-backed growth models to predict your adult
height — then lets you measure yourself right now using your
iPhone camera. No tape measure. No guessing. Just clear answers
based on real data.

Enter your age, current height, and your parents' heights.
TallTell runs the mid-parental height formula and Tanner stage
growth model — the same methods used in pediatric medicine — and
shows you your estimated adult height and where you are on your
growth curve.

Then point your camera and measure your height instantly.
AR body detection gives you your current height in under
3 seconds, accurate to ±0.5 cm, with no equipment needed.

BUILT ON REAL SCIENCE

TallTell's predictions use the same growth data trusted by
paediatricians worldwide. The mid-parental height formula and
Tanner stage percentile charts have guided clinical height
estimates for decades. Our AR measurement uses Apple's
body-detection framework for accurate, hands-free results
every time.
