Very few studies have been done to determine the accuracy of heart rate monitoring on the Apple Watch. One small study from 2018 showed that the Apple Watch was accurate when assessing heart rate variability during a relaxed and emotionally stressed state. However, it only takes short readings w...
Not unless it’s a professional heart rate monitor. While wristbands like Withings, MiFit, Xiaomi and Fitbit can track heart rate, the measurement accuracy of these devices isn’t good enough to track heart rate variability yet. Once pulse trackers are accurate enough, we’ll gladly let you ...

To further our understanding of this often-neglected component of sleep, the objective of this work was to investigate the association between bedtime regularity and resting heart rate (RHR): an important biomarker for cardiovascular health. Utilizing Fitbit Charge HRs to measure bedtimes, sleep and...
That might suggest why your wearable is a bit iffy when monitoring your sleeping habits. They even released the source code for their heart rate variability analysis, so there’s a nice afternoon read if you were looking for one. What really stood out to us about their work is how they ...
Heart rate variability (HRV) denotes the time interval between consecutive heartbeats.The HRV signal, as detected by the sensors and devices, has been popularly used as an indicative measure to estimate the level of stress, depression, and anxiety. For years, artificial intelligence (AI)-based ...
Heart rate variability decreases with age. I’m very competitive. And if you are too, it’s all too easy to start comparing your HRV data with other people’s. Don’t do that! HRV is a highly personal metric that’s influenced by age (the older you get, the lower your HRV will be...
For heart rate accuracy, consider a heart rate monitor chest strap above all else. Chest straps are more precise than wrist-worn wearables and can quickly pick up on important and telling nuances when working out. However, for a device with more utility, choose a wrist-worn tracker or fitne...
Keep the above statement in mind when you use your Fitbit to measure your heart rate variability. Though Fitbit strives for high accuracy when designing the heart monitoring element of its fitness watches, these devices likely cannot perform as accurately as dedicated scientific tools. It is there...
