During the night, your body goes through a series of sleep cycles comprised of five different stages. The average adult will experience four or five cycles each night, that include light stage-one sleep, slightly deeper stage-two sleep, heavy stage three, stage-four "Delta Sleep," which is when your body rebuilds itself, and REM sleep, a unique stage during which people dream and experience significant physiological changes. Pinpointing the moments within each cycle when you are naturally closest to waking makes this alarm system truly unique.
Depending on your schedule, you can set an alarm window to last for up to 90 minutes. Since your alarm sounds at the moment during the preset alarm window when you are most alert, you will wake up refreshed instead of groggy. World travelers, business associates, busy parents, and students with early morning classes are particularly likely to enjoy the edge this gives them during the first hours of every day.
Monitoring Your Sleep Data for a Healthier Lifestyle
By using the mode button to select "data review," you can review a chronological list of the previous night's almost-awake moments. The unique "Data A" reading indicates the average time between your almost-awake moments. This reading can help you know how soundly you are sleeping. A longer Data A reading than normal may indicate a particularly restful sleep, while a shorter Data A reading and an increased number of almost-awake moments may indicate a restless night.
Taking a look at what you did prior to bed on those restless evenings can help you better understand how your waking life affects your sleep patterns. Activities such as smoking, late-evening exercise, and eating a big, spicy meal can significantly impact your night's rest and your Data A reading. The Pro model offers an expanded 12-hour window of sleep data collection.
Software included with the Pro model helps you keep track of these lifestyle factors. Simply use a USB connection to transfer sleep data from the SleepTracker watch to your computer, enter any factors you want to track, and the details of your nights become available for quick and easy comparative reviews. This helps you see the serious sleep benefits of small lifestyle adjustments.
The Only Watch You Need
The SleepTracker's innovative almost-awake technology can be set to wake you with a vibrating alarm, a ringing alarm, or both at the same time. Featuring a sporty, sophisticated look that helps it do double-duty as an everyday watch, the SleepTracker has an easy-to-read digital display with time, day, and date readouts. Also offering a GLO back-light for easy nighttime reference, and water-resistance, the SleepTracker is ready to take on your busy days and help you achieve restful nights.

As others had noted, the vibration and audible alarms are not sufficient to wake people out of a deep sleep.
The software for analyzing the data is rather simplistic for my taste, but here's the good news, the data are stored in native MS Access format!
Problem is, if it doesn't find one of those "almost awake" moments, it rings at the time you set, no matter how deep you sleep.
I can't give this disappointing product a 1-star review because it did manage to wake me up, even with the weak vibrate/beep function. Read morePublished on April 30, 2009 by Elena
I was hopeful this would work. I agree wiith the premise; that where you wake in the sleep cycle matters, but this product doesn't deliver. Read morePublished on March 15, 2009 by James T. Duncan
