The new Apple Watch can, among other things, measure the wearer’s heart rate. But how accurate are its measurements?
To find out, an engineer named Brad Larson measured his heart rate readings on the Apple Watch against his heart rate readings using a Mio Alpha, an incredibly accurate device. You can see the comparison, which Larson tweeted out, below:
That’s…pretty accurate! Of course, this is only one trial, and not a comprehensive test. But those are encouraging tests for those who want to use the Apple Watch to check their heart rate as they exercise. And it’s even more encouraging considering how poorly fitness trackers have been shown to measure certain other movements.
