Best wearable for HRV
The best wearable for HRV?
Heart rate variability is the clearest window into your autonomic nervous system and recovery. Accuracy depends on sensor contact and overnight sampling, so a chest strap is the reference standard and rings and recovery bands lead among all-day wearables.

22 devices scored1
Polar H10Chest heart-rate strapAn ECG chest strap is the validated gold standard: a 2022 study found near-perfect agreement with a reference ECG for HRV (r = 0.95 at rest, r > 0.93 during exercise), which is why researchers benchmark other devices against it.Sensors 2022 (vs ECG) ↗962
Garmin HRMChest heart-rate strapReads RR intervals from the heart’s electrical signal like a Polar strap, feeding cleaner HRV to Garmin watches than any optical wrist sensor.923

What is the best wearable for HRV?
For most people, the Polar H10 is the best wearable for HRV. An ECG chest strap is the validated gold standard: a 2022 study found near-perfect agreement with a reference ECG for HRV (r = 0.95 at rest, r > 0.93 during exercise), which is why researchers benchmark other devices against it. The Garmin HRM is a strong runner-up. That said, the "best" device depends on the rest of your goals. Vora can coach on HRV data from any of them.
Is the Polar H10 or Garmin HRM better for HRV?
For HRV specifically, the Polar H10 edges ahead (96 vs 92 in our scoring). An ECG chest strap is the validated gold standard: a 2022 study found near-perfect agreement with a reference ECG for HRV (r = 0.95 at rest, r > 0.93 during exercise), which is why researchers benchmark other devices against it. However, Garmin HRM may win overall if your other priorities differ.
Can Vora use HRV data from any wearable?
Yes. Vora reads HRV and related signals from Oura, WHOOP, Garmin, Apple Health, Fitbit, Samsung Health and more, then reconciles overlapping sources and turns the result into a daily plan. You keep your device; Vora is the coaching layer on top.
How is this HRV ranking scored?
Each device is scored 0-100 on HRV based on sensor quality, form factor and how the signal is captured (for example, overnight versus spot samples, or GPS versus inferred estimates). Heart rate variability is the clearest window into your autonomic nervous system and recovery. Accuracy depends on sensor contact and overnight sampling, so a chest strap is the reference standard and rings and recovery bands lead among all-day wearables.
