Apple details the technology and functionality behind Apple Watch’s heart rate monitor
Ahead of the Apple Watch making its way onto the wrists of consumers, Apple has published a new support page detailing the device’s heart rate monitor. As we know, the Apple Watch includes a heart rate reader to measure a person’s intensity during workouts.
With knowledge of this intensity data, the Watch is able to more accurately measure the amount of calories a person burns per day. Additionally, a user can check their heart rate at any time using a feature known as the Heart Rate Glance. But beyond these two user functions, this new support document details the technologies behind the hardware as well as some little known software features.
According to the document, the Apple Watch will silently measure your heart rate every 10 minutes. This data will be stored in the iOS 8 Health application for later viewing and integration with third-party health tracking applications and hardware.
