Sleep Apps and Shared Beds I've seen on the marketplace now several alarm clock applications that claim to analyze your motion patterns in your sleep, so as to determine the ideal time to wake you up such that you feel refreshed.  I am intrigued by this possibility;  however, I do not sleep alone.  Does anyone know if these apps work well, or even at all, if there are multiple individuals in the bed, each presumably moving on their own sleep cycle?
No, it would probably not work if you don't sleep alone unless the one you sleep with don't move at all in their sleep.
