I've been noticing my sleep patterns (as much as I can) lately and was wondering if there is a device (not a smart phone) that tracks your sleep? I guess something you wear on your wrist.

I know I snore (my wife used to wake me up so that I could go back to sleep (on my side instead of my back)). And I also pop awake at odd times of the middle night.

I'm trying to get an appointment to get evaluated for sleep apnea - knowing how important it is to get a continuous 7 hours a night.
