Interesting app! It seems like a lot to remember to put your phone under the covers and make sure it doesn't fall off in the middle of the night (at least for me). Additionally, I've always loved having the phone in the dock next to my bed, since it doubles as a clock for me in the middle of the night.

Do you know if the Sleepcycle app is able to differentiate between your movements and someone else's? It seems like this wouldn't be possible?

This is obviously a totally different price point, but it seems like bringing a hardware-based solution here does offer some real and very tangible benefits.
