How accurate is the heart rate monitoring on the ring?

Heart rate monitoring is a core indicator of health management. In the past, we often obtained this data through watches and chest straps. Now, a small smart ring can also provide real-time heart rate monitoring. So, how accurate is the heart rate data from the ring? This article will explain the principles and value of this information.

1. Monitoring Principle

Smart rings typically use an optical sensor (PPG) to calculate heart rate by detecting changes in light reflected by blood flow. This principle is similar to that used in smartwatches and medical devices.

2. Accuracy in Everyday Conditions

During rest, sleep, and light activity, the ring's heart rate monitoring is roughly equivalent to that of a smartwatch.

Because the ring conforms to the finger's blood vessels, the signal is stable and the data fluctuations are minimal.

3. Performance in Sports Scenes

During high-intensity exercise, hand movement increases interference and may lead to some errors.

However, compared to watches, rings are less affected by sweat and the tightness of the wearer's wrist.

4. Comparison with Professional Devices

Multiple tests have shown that the ring's heart rate monitoring accuracy is within ±2–3 bpm in most cases.

It's sufficiently accurate for daily health management and sleep tracking.

✨The smart ring's heart rate monitoring data is highly accurate in daily life and during sleep. There may be slight errors during exercise, but overall, it's sufficient to meet most health needs. It makes heart rate tracking effortless and seamless, making it an ideal choice for daily health management.
