Set SleepTracker®'s alarm for the normal time you start your day, then adjust the alarm window to allow SleepTracker® to wake you at your body's optimum time, if SleepTracker® detects an almost-awake moment within the window before your alarm.

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.
When you sleep, your body goes through a series of sleep cycles. The average adult experiences 4-5 full sleep cycles over an 8-hour period. Each cycle lasts about 90-110 minutes and comprises five different stages, as illustrated by this chart.
No two people have the same sleep cycles, and nobody has the same cycle twice. Many factors can influence sleep cycles, including diet, exercise, medications, drugs or alcohol, stress, sleep disorders, and sleep deprivation. Age and gender can play a role, too: women tend to sleep more soundly than men, and as we age, we sleep more restlessly.
A typical sleep cycle has five stages and takes 90-110 minutes. During Stage 1 of your sleep cycle, you sleep lightly. At Stage 2, your sleep gets progressively deeper. At Stages 3 and 4, also known as "Delta Sleep," you sleep most heavily; this is when your body rebuilds itself.
Stage 5 of sleep, also known as REM (rapid eye movement) sleep, is marked by extensive physiological changes, such as accelerated respiration, increased brain activity, rapid eye movement, and muscle relaxation. People dream during REM sleep.
In the first third of the night, Delta sleep stages last longer than REM stages. As the night progresses, Delta sleep diminishes in length. By the last third of the night, Delta sleep usually ceases, while REM stages lengthen.
SleepTracker® may find multiple almost-awake moments within the sleep cycle. Almost-awake moments may also vary in frequency throughout the night.
By monitoring your sleep cycles for optimal waking moments during the preset ALARM WINDOW, SleepTracker® finds those almost awake-moments and gently wakes you when you're most alert. The result? You wake up refreshed instead of groggy. Waking up has never been easier.
