How accurate are these heart-rate tracking apps? ... When researchers compared four of them to clinical gold standard measurements (ECG and fingertip pulse oximetry), they found that the heart rate readings generated by apps were off by more than 20 beats per minute in over 20% of measurements.

Conclusions. The most recent Fitbit Charge 2 presents level of accuracy for HR measurement and performances unchanged from existing models of the same brand. Whilst there is only moderate bias on average, precision is poor for individual measurements, which could plausibly be underestimated by as much as 30 bpm.

The accuracy within 10 bpm was 100 percent, 100 percent and 88 percent for Apple, Samsung and Fitbit, respectively. The rate or type of PSVT, age and sex did not influence device accuracy.

While some wrist-worn monitors are more accurate than others, studies show they generally aren't as accurate as chest-worn heart monitors, says Chairman of the Department of Thoracic and Cardiovascular Surgery Marc Gillinov, MD, who has studied the accuracy of these devices.

Most heart rate sensors on treadmills or ellipticals are fairly accurate but I would never trust them over a heart rate chest strap. If you need to have a general idea of your heart rate during a work out, the on-board sensors should give you just that.

In fact, the study claims that the Fitbit Surge was the most accurate with energy expenditure tracking, with an error rate of around 27 percent. The Microsoft Band came in at around 33 percent, while Apple Watch reported an error rate near 40 percent, though it was consistent.

Accuracy vs. A highly accurate at-home EKG monitor can measure the electrical activity of your heart from up to six different angles. Six-lead EKGs are highly sensitive and they can detect subtle fluctuations of the heart that could help you get ahead of a developing disease in its early stages.

The heart rate tracking was frequently inaccurate during runs and high-intensity activities. It's worth it, but there's no doubt the Fenix 6 Pro is expensive.

The Verdict. Most people would agree that heart rate monitors give users a good idea of your heart rate. Please remember, all heart rate monitors are not foolproof for accuracy. The heart rate monitors listed in the link have been tested and found to be as accurate as medically possible by myself and colleagues.

A stylized letter F. The Apple Watch heart rate monitor may be accurate for detecting atrial fibrillation in older people. However, research has found that this accuracy rate is only about 34% overall, and further studies are needed to confirm when the Apple Watch heart rate monitor is most useful.

A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise.

The heart-rate sensor isn't perfect Unlike with the Forerunner 225, the sensor on the 235 will run continuously throughout the day. Like its predecessor, I found the heart rate data to be relatively accurate. Resting heart rate fluctuated between 47 and 50 beats per minute (bpm), which is normal for me.

The limitations of tracker and treadmill calorie counts A study at Stanford University assessed different devices to check their accuracy. The results showed that the most accurate of them was off by an average of 27 percent and the least accurate by 93 percent.

The researchers found substantial differences in accuracy between the four apps. In some apps there were differences of more than 20 beats per minute compared with ECG in over 20% of the measurements.

As for its heart-rate-monitoring accuracy, MyZone rate it as 99.4% as accurate as an EKG (electrocardiogram).

The most accurate device for checking your heart rate is a wireless monitor that's strapped around your chest. It reads out to a fitness tracker worn on your wrist. Digital fitness trackers worn on the wrist, at-home blood pressure machines, and smartphone apps are less accurate than checking your heart rate manually.
