BreathLife measures how well you breathe. A 60-second breath-hold test (CO₂ tolerance), free in your browser or the app, gives you your breathing level and your breathing age. Then a 28-day voice-guided path, 5 minutes a day, helps lower it: 10 exercises (box, coherent, 4-7-8...), a re-test every week, streaks, and a Sunday 8 pm session where everyone breathes together. Your first session is on us. Not a medical test, just an honest way to build a daily breathing habit.
