Apple Watch Hrv-Capable?
From the announcement info given today:
"On the back of the case, a ceramic cover with sapphire lenses1 protects a specially designed sensor that uses infrared and visible-light LEDs and photodiodes to detect your heart rate."
Will this tech be sensitive enough from the wrist to detect HRV in a meaningful way? For anyone that doesn't currently own a high-quality HRM, the price of this Apple product effectively comes down.
