How accurate is the heart rate monitor on a Fitbit?

Compared with the ECG reading, wearable products varied in their accuracy. The Fitbit Charge performed the best at rest, measuring within 5 beats per minute of the ECG reading 95% of the time.

The Fitbit Versa 3 allows a user to track their steps and heart rate and monitor the oxygen levels in their blood.

Originally, the heart rate monitor was very accurate (checked against a stationary bike from ~110 - 160 BPM). Now in Jan 2022 it is wildly inaccurate.

But occasionally, their estimates of heart rate could swing too high or too low. At rest, the Fitbit Surge was most accurate; Basis Peak was least accurate, the study authors said. During exercise on a treadmill at 65 percent of maximum heart rate -- defined as 220 beats per minute minus age -- accuracy suffered more.

The Fitbit Versa 3 uses the new PurePulse 2.0 heart rate sensor, the same found in the Fitbit Sense. Not surprisingly, it is still a wrist-based optical heart rate sensor, providing acceptable heart rate readings.

The updated Sense 2 replaces the original Sense in Fitbit's line up and packs in sensors to monitor heart rate, heart rate variability, and skin temperature. It's also the first time Fitbit has added what it calls a 'body response' sensor.Oct 14, 2022

The two models share the same GPS and heart rate tracking functionality and offer the same sleep options. Both also have the Active Zone feature and can monitor the oxygen levels in a user's blood.

Fitbit is a company that produces fitness tracking devices and wearable technology. The Fitbit Charge 2 is a device that monitors heart rate and blood pressure. The device can be worn on the wrist or ankle.

The Fitbit Charge 5 is among the most accurate for measuring steps and heart rate (although accuracy isn't everything). It reliably detects, nearly always correctly identifies, and automatically begins to record workouts—running, walking, biking, swimming—after about 10 minutes of activity.

Purepulse Best Practices

Fitbit PurePulse™ trackers help you get the heart rate stats you want, right on your wrist—automatically, all-day, during workouts and beyond—with no need for an uncomfortable chest strap. Like all heart-rate monitoring technologies, accuracy is affected by physiology, location of device, and different movements.

According to a study on Fitbit accuracy published by the NCBI, researchers found that Fitbit devices were €œacceptably accurate for step counting about 50% of the time. Additionally, they found that accuracy increased depending on where the device is worn: For jogging, wrist placement was the most accurate.
