MacRumors:
In a new study comparing the accuracy of seven different fitness trackers, the Apple Watch was found to have the lowest margin of error when measuring heart rate, beating the Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn, and Samsung Gear S2.
Researchers set out to determine the accuracy of wrist-worn devices at measuring both heart rate and energy expenditure, aka calories burned via physical activity. 60 volunteers participated, including 29 males and 31 females, each of whom wore several fitness trackers and completed activities like cycling, running, and walking.
If these numbers are important to you (and they are for a lot of people), it’s good to know the Apple Watch comes out ahead.
I hate having to wear a watch at all, but my series 2 AW does a great job of tracking HR. I also like being able to track my sleep with a third-party app and that also includes HR as a metric.
Curiously, I rarely use AW as a time piece, so maybe it should be classified as a ‘health monitor’, rather than a ‘watch’.
Good on measuring HR but poor on energy expenditure, according to the study.
That’s been my personal experience and my only real complaint.
As often as my Apple Watch reads double or half my actual heart rate, I’m really glad I didn’t buy a Fitbit instead.
I read the full report. You’re making too much out of Apple’s performance relative to everyone else.
“We found that in most settings, heart rate measurements were within acceptable error range (5%). In contrast, none of the devices provided estimates of energy expenditure that were within an acceptable range in any setting. …”
i rarely make calls on my smart “phone” either
