Why would I purchase this as opposed to using http://www.sleepcycle.com ?
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.
That said, cool product, best of luck, and I hope you guys get funding!
