Notes about Heart Rate detection.

The heart rate measurement is independent of the Wear OS Heart Rate application.
The value displayed on the dial updates itself every ten minutes and does not also update the Wear OS application.
During the measurement (which can also be triggered manually by pressing the HR value) the value turns red until the reading is completed, then it returns to white.
