How can you measure sleep quality ?

  I think the iwatch has a function that tracks your movements during sleep and can make some kind of qualitative assessment.

    It seems to be measuring movement and heart rate

    If the watch tells you you’re sleeping bad do you think it makes you feel worse physically? There should be an app that measures your physical reaction to checking the sleep quality app.

  How tired you are the next day, perhaps.
