  You're honestly comparing the accuracy of a product out in the market, with one in the patent stages back in 2013? I understand being skeptical of the accelerometer + hr monitor solution, there are certainly more involved ways of analyzing patterns that are available to sleep specialists. But how does it help the discussion to dismiss it in favor of a non-existent product?

    My point is, a sensor in the pillow might be more accurate in tracking your sleep than a fitness tracker. Thats all!
