Medicine 3.0 for yournervous system.
Peter Attia's Medicine 3.0 framework says we need to intervene before stress becomes disease. Every other app tells you you're stressed. Vayu does something about it — in real time, silently on your wrist.

The Science
This isn't spirituality.It's physiology.
The autonomic nervous system is trainable — the same way a muscle is. Controlled breathing shifts CO₂ tolerance, vagal tone, and HRV. Those three levers directly modulate your stress response. Vayu closes the loop in real time: if your HRV drops, it adjusts the cadence. If your heart rate spikes, it triggers a recovery sequence. That's closed-loop biofeedback. Everything else is a timer.
Closed-Loop Biofeedback
HRV, heart rate, and respiratory rate read in real time from Apple Watch or Wear OS
28.6% HRV Improvement
199-person clinical study, p < 0.001, paper under review at SAGE Journals
64% Day-30 Retention
2.5x the mindfulness app average — zero paid acquisition
No Screen Required
Silent haptic guidance on your wrist. The only intervention that doesn't add screen time.
