The Key to Waking Up Refreshed
Why is it so hard to wake up to a normal alarm clock? Because a normal alarm clock can't detect where you are in your sleep cycle - a continuous cycle from deep sleep, to brief almost-awake moments, and back to deep sleep again. Occasionally, your alarm may catch you at an optimal, almost-awake moment and you wake up feeling refreshed, but usually you grope for the snooze button waking up tired and groggy.

Wake at Your Perfect Time
SLEEPTRACKER^® puts an end to that tired feeling. Once you set its alarm window, it monitors your body and continuously looks for your optimal waking times so it can wake you at just the right moment. Imagine not feeling tired in the morning and getting a few extra minutes out of your day.
