Features & Capabilities

The Vagal HRV transforms your Polar H10 sensor into a heart rate variability (HRV/HRV) lab in your pocket. Connect via Bluetooth to view your live ECG, measure your HRV with clinical-grade accuracy, and train your breathing with real-time biofeedback.

The Vagal HRV was created with one goal: to be the honest HRV lab. No hidden signatures, no "black boxes," and a total focus on the accuracy of your data.

KEY FEATURES

• Reliable HRV measurement — RMSSD, SDNN, and heart rate (max/average/min) calculated from the actual RR intervals of the Polar H10.

• Live ECG — track your heart's electrical signal in real time, right on the screen.

• Guided breathing — pulsating circle and soothing sounds guide your breathing in 4 phases (inhale, hold, exhale, hold).

• Heart Rate Coherence (RSA) — see your heart rate oscillate in sync with your breathing and track your coherence index live.

• Resonance Frequency — discover the breathing rhythm that amplifies your HRV.

• Daily Readiness — understand your recovery status with a transparent and objective method.

• History and Trends — track the evolution of your RMSSD over time.

• Data that's yours — export your sessions in CSV or generate PDF reports. No locks.

• Multilingual — available in 10 languages.

WHY A POLAR H10?

Watches and rings estimate heart rate by light (PPG), which is less accurate. The Polar H10 captures a real chest ECG, the gold standard for measuring HRV. This means much more reliable RMSSD and SDNN to track your training, stress, and recovery.

WHO IT'S FOR

• Athletes who monitor recovery and readiness.

• Practitioners of meditation, mindfulness, and breathwork seeking objective feedback.

• Those interested in biohacking who want to understand how stress and sleep affect their physiology.
