Worn like an everyday watch, SLEEPTRACKER is ideal for anyone who wants to wake up alert and ready to start the day, such as frequent travelers across time zones, business people looking for an extra edge, students with fluctuating schedules, or busy moms who need to wake up easily. SleepTraker PRO connects via USB to your computer, so you can download sleep data, make night-over-night comparisons, and keep track of other factors influencing your sleeping patterns with the included software. The Pro also offers three alarm choices: Vibrating, Ringing, or Both. Plus it features a sleek new metallic design. Why it Works 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. How does SLEEPTRACKER® work? SLEEPTRACKER continuously monitors signals from your body that indicate whether you are asleep or awake. Because you wear SLEEPTRACKER® on your wrist like a watch, its internal sensors can detect even the most subtle physical signals from your body. SLEEPTRACKER finds your best waking moments, so that waking up has never been easier.
