Or similar ....Have not used but read review in FastCompany. It's a computerized sort of bracelet thingy that you can set to wake you up, which it does by vibrating. Since it's on your wrist, it seems unlikely to also wake up MrsAustin316.
As an aside, it also somehow knows the optimal time to wake you up based on REM or deep sleep or something. So, for example, if you set it for 6:30 am, it will vibrate some time between 6:00 and 6:30, but do so such that it gets you up when you're in your lightest sleep so you'll feel more energized when you wake up.
Also, this is second release of the product. V1.0 had lots of issues which article says they resolved.
