About this device

This clip-on biofeedback sensor measures heart rate variability (HRV) and coherence using a medical-grade photodetector at 125 Hz. It connects via Bluetooth to the HeartMath app on a smartphone (Android v5+ or iOS 13.0+) to display real-time feedback and guide breathing and relaxation exercises. It has an 80-hour battery life and charges via USB.

What can I use this for?

  • Monitor heart rate variability and practice coherence breathing with real-time visual feedback
  • Track stress and relaxation patterns over time through the HeartMath companion app
