Breathwork That Proves Its Impact
Vayu is a screen-free breathwork platform that pairs real-time haptic guidance on the wrist with HRV-informed sessions, developed in an ongoing research partnership with Simon Fraser University. Built for clinical integration and enterprise wellness programs.
A 199-participant naturalistic pilot found HRV increased 28.6% (median), resting heart rate decreased 7.4 bpm, and perceived stress (PSS-10) fell 2.5 points (16%), with no adverse events. About 29% of enrollees sustained three or more sessions a week, so these outcomes describe that subgroup. Uncontrolled and unblinded, so they are associations rather than evidence of causation. Under peer review; medRxiv preprint available, though the posted version predates this correction. SFU Metacreation Lab, NRC IRAP supported.

Built With Researchers, Not Just for Marketing
Developed in an ongoing research partnership with the SFU Metacreation Lab, supported by NRC IRAP funding. Research focuses on wearable biosensors, HRV, and breath-based autonomic regulation.
Active research partnership. Vayu is working with the SFU Metacreation Lab on breath-based autonomic regulation using wearable biosensors and post-session HRV from Apple Watch and Wear OS. This collaboration is supported by NRC IRAP funding. Research is ongoing.

HRV Biofeedback Without Screens
Vayu guides the breathing pace through haptic vibrations on the wrist, then reads HRV from the smartwatch after each session and uses it to shape the next one. No app to stare at. No audio cues to disrupt your environment.
Measure
Heart rate from the watch during the session; HRV (SDNN) read from Apple Watch or Wear OS after it. No additional hardware.
Adapt
Vayu reads your HRV after each session and uses the trend to shape the next one. Pace, length, and technique adapt between sessions, not mid-breath.
Guide
Haptic pulses on the wrist signal inhale, hold, and exhale. Screen-free. Works during meetings, commutes, or clinical sessions.
Built for Clinical and Enterprise Scale
Corporate Stress Management
Employees use Vayu during work breaks. 2-minute guided sessions have measurable impact on afternoon cortisol and focus.
