It displays something on there but “The majority of wrist-worn fitness devices and trackers track your heart rate through your skin. Unfortunately, this means they usually aren't sensitive enough to detect heart rate variability accurately.”
HRV is an interesting field. Too high and it can indicate arrhythmia. Too low is also not good.

- NoPicklez 3y agoI think with all these devices "accurately" is a loose term in the sense that it is accurate enough, but could be better. Wrist based ECG has been determined as accurate enough to wear on your wrist, but isn't as accurate as what you'd get in a hospital. If it is accurate enough, then the particular number isn't necessarily the important, its whether it an measure the same number consistently, then track movements from the baseline. Which is why they often have a % up/down accuracy figure.
