Breath & HRV Coach
Built for Gary Brecka · Human Biologist
Real-time breath pacing with heart-rate-variability feedback and a clean session history.
Wellness tool only — not a medical diagnostic. The adaptive pacing loop is the real logic; the HRV signal is either your device camera (processed on-device) or a simulated on-device stream. Biometric data never leaves the device without your explicit consent. Consult a physician before health decisions.

Breathing protocol
Adaptive pacing on. When your live coherence falls below 45, the pacer lengthens the exhale by 0.5s a breath (capped at +2s) and eases it back as you recover. Toggle it in Settings.
