Taller Ninja
Train like a ninja.
Grow into your potential.
The honest habit app for teens: posture, exercise, food and sleep during puberty. Daily training, streaks and belts — from white to black.
Your daily training
Posture & stretching
Guided exercises with built-in timers: wall posture, chin tucks, bar hangs and more. Standing tall is height you already own.
Eat like you mean it
Meal ideas and the nutrients behind them — protein, calcium, vitamin D. No calorie counting, ever.
Sleep is training too
Growth hormone is released in deep sleep. Fixed bedtimes, 8–10 hours, and a sleep posture setup.
Track your growth
Log your height monthly and see it against the estimate doctors use — the mid-parental method, honestly explained.
Earn your black belt
Every training day earns XP. Keep your streak alive, unlock badges and climb the belt ladder.
Why Taller Ninja is honest
- No miracle claims — we tell you what works and what does not.
- We never sell supplements or "growth" products.
- Our height estimate uses the same method pediatricians use.
- Your data stays on your device. No tracking, no ads.
Genetics set your range — sleep, food and movement decide whether you reach the top of it. Taller Ninja is not medical advice. Talk to a doctor if you have questions about your growth.
