BreathLife: Breathing Age Test

What if you could measure how old your lungs really are?



BreathLife gives you a breathing age — not just a number, but a roadmap to better health. Take the free 60-second CO2 tolerance test and find out where you stand. Then let the app do the rest.



YOUR BREATHING AGE IN 60 SECONDS
Our CO2 tolerance test measures how efficiently your body uses oxygen. Most people discover they breathe years older than their actual age. The good news: it's completely reversible with the right exercises.



A PROGRAM BUILT FOR YOU
Based on your breathing level, BreathLife selects the exercises you actually need:



- Box Breathing
- Diaphragmatic Breathing
- Extended Exhale
- Alternate Nostril Breathing
- Kapalabhati: energize and cleanse with rapid breath cycles
and more



Every session is guided, timed, and tailored to your level — from Young to Exceptional.



WATCH YOUR BREATHING AGE DROP
After each test, your breathing age updates. The progress chart shows your improvement session by session — a clear, motivating proof that what you're doing is working.
