About this app

The Vagal HRV transforms your Polar H10 sensor into a heart rate variability (HRV/HRV) lab in your pocket. Connect via Bluetooth, measure your HRV with the precision of a chest strap, and train your breathing with real-time biofeedback.

Made for both those seeking PERFORMANCE and those seeking CALM.

KEY FEATURES

* Reliable HRV — RMSSD, SDNN, and maximum/average/minimum HR from the Polar H10's actual RR intervals.

* Readiness — a score compared to your own baseline, with green/yellow/red signal.

* Guided breathing — pulsating circle and soothing sounds in 4 phases, with protocols (Coherence 6, Box, 4-7-8, extended exhalation).

* Heart rate coherence (RSA) — see your HR oscillate in sync with your breathing, live.

* Consistency training — daily program with a streak and a goal that grows weekly.

* Find your resonance frequency — discover the breathing that most amplifies your HRV.

* Context tags and insights — tag sleep, alcohol, training, stress and see what affects your HRV.

* Trends, history and backup — 7/30 day averages, best time of day and CSV/PDF export.

* Practice breathing without a sensor, and 10 languages.

WHY A POLAR H10?

Watches and rings estimate heart rate by light (PPG). The Polar H10 is a chest strap that measures heart rate intervals directly, the gold standard for HRV — much more reliable RMSSD and SDNN.
