“iOS developer Brad Larson has taken heart rate data from the Apple Watch and compared it to a dedicated Mio Alpha heart rate monitor he also had on during a run,” Gary Ng reports for iPhone in Canada.
“Larson was able to compare the data as he made a quick iPhone app ‘that ran a query for all recent samples and generated CSV output from that,’ which we see in the chart below,” Ng reports. “Essentially, Apple Watch performs exactly like a dedicated heart rate monitor (which costs $169) with very accurate results, by using photoplethysmography.”
