DISCOVER YOUR POTENTIAL
See your growth potential.
Tallify turns the science of sleep, nutrition, and training into one personalized daily plan — built around your body, for ages 13 to 25.
Coming soon to the App Store & Google Play.
An illustration of how Tallify maps your range.
Most growth apps sell you a promise. We show you the math.
Your height isn't only genetics. Sleep, nutrition, posture, and training shape how much of your natural potential you actually reach — and Tallify turns that science into a plan you follow every day.
THE SCIENCE
Built on real science. Honest about the limits.
- 01
The mid-parental formula
A height-prediction method refined in research since the 1970s, based on your parents' heights.
- 02
Adjusted for you
Tuned for your age and biological stage, so your range reflects where you actually are.
- 03
Layered with your habits
Sleep, nutrition, and training quality shape how much of your potential range you can reach.
We show you a potential range — never a guaranteed number. That's the honest part most apps skip.

Questions, answered honestly.
01 Does Tallify guarantee I'll grow taller?
No app can guarantee a specific height. Tallify helps you build the daily habits — sleep, nutrition, training, posture — that support healthy growth, and shows your potential range based on the science.
02 Is this medical advice?
No. Tallify is a guidance and tracking tool, not a medical device. Predictions are estimates for planning, not diagnoses. Always talk to a doctor about your health.
03 How is my potential range calculated?
It starts from the mid-parental height-prediction method, adjusts for your age and biological stage, and layers in your sleep, nutrition, and training quality. You'll always see a range, never a single promised number.
04 What ages is Tallify for?
Ages 13 to 25 — the years when daily habits can support your natural growth the most.
05 How much does it cost, and can I cancel?
Start with a 3-day free trial. After that, choose a monthly or 6-month plan. You can cancel anytime in your store account settings; current pricing is shown in the app.
06 Is my data private?
Yes. Your data stays yours, you can delete your account and data anytime, and we never sell it. See our Privacy Policy for details.
Your potential is waiting. Start the climb.
Sleep, nutrition, training, and one honest plan — built around you.
