## What is Tallzo?

How tall will you actually get?

Not a guess. Not a vibe. A real prediction based on your genetics, sleep, food, and how you move.

Tallzo is the only height app built around the science of what you can actually control. Up to 20% of your final height is determined by your lifestyle habits during your teen years. Most guys never optimize that 20%.

You're about to.

YOUR PERSONAL HEIGHT PREDICTION

Enter your parents' heights, your age, and your current habits. Tallzo runs the numbers and shows you:

- Your predicted height range
- How much your habits are helping (or hurting)
- What changes would move your prediction higher

This isn't a generic calculator. It's your number, based on your life.

MEET ZO

Zo is your bamboo growth companion. He grows when you do.

Log your sleep - Zo gets taller.
Hit your nutrition targets - Zo gets stronger.
Stay consistent - Zo levels up.

Skip a day? Zo notices. But he never shames you - he challenges you to come back.

THE THREE PILLARS OF HEIGHT OPTIMIZATION

SLEEP
Growth hormone is released during deep sleep. Tallzo tracks your sleep window and tells you if you're hitting the window that actually matters.

FOOD
Your growth plates need protein, zinc, vitamin D, and calcium. Tallzo's AI meal logger scans your food and shows you exactly what you're getting and what's missing.

MOVE
The right exercise stimulates growth. The wrong kind compresses your spine. Tallzo tracks your movement and flags what's helping vs what's not.

AI MEAL PHOTO LOGGING

Point your camera at your plate. Tallzo identifies what you're eating and logs the nutrients that matter for growth in seconds. No calorie counting. No manual entry. Just take the photo.

BUILT FOR TEEN GUYS

No fluff. No shaming. No pseudoscience.

Tallzo is designed for guys aged 13-18 who want real answers about their height and a daily system to maximize what's possible.

Your genetics set the ceiling. Your habits determine whether you hit it.

SCIENCE, NOT HYPE

Everything in Tallzo is grounded in peer-reviewed research on endocrinology, bone development, nutritional science, and sleep science for adolescent development.

We don't claim to make you taller than your genetics allow. We help you reach your actual potential - which most guys never do.
