    Here is some info directly from Apple on the heart rate monitor: https://support.apple.com/en-us/HT204666
    Thanks good info on the technology. No mention of skin tone's effect though.

    Why wouldn't it?
    The Apple watch uses both green light and infrared to see the blood inside your skin. I'm wondering if melanin in the skin (i.e. dark skin) would obscure the light passing through the skin.

    It seems like a perfectly reasonable question to me. And I've tried to ask it as seriously and scientifically as I can. But apparently some people's think I'm being unreasonable or just trolling. smh

    Nope. I use the Fitbit charge and it uses the same rate system. Green LED that flicker and the sensor reads skin regardless of skin color. Pulse Ox works the same way on the finger tip

    Finger tip pulse ox gives me no comfort because finger tips are not brown. But I'm glad to hear that the Fitbit Charge works. That makes me feel better.

    THANK YOU iEd!!!

    See! Completely legitimate question and one with precedent because apparently it's been a problem with similar technology in the past.

    Although the article takes away the confidence that John Yester's Fitbit just gave me. John have you tested it with different skin tones?

    This was a good find; well done.

    I can't wait to get an Apple Watch and compare its accuracy to the Mio and chest-mounted designs.

    And interesting to see that practically, if you have darker coloured skin, the bottom line is, your battery drains faster. But I'm guessing, better that than get crap readings.

    Does this mean the technology is racist?!?!?!
