REM (Rapid Eye Movement) is a light sleep stage–it is the ideal stage to wake up at to feel refreshed and well-rested.

This stage is characterized by a random movement of eyes, low muscle tone throughout the body, and occurrence of vivid dreams.

REM phases are marked on the Night sleep graph with blue rectangles.

Using the “Smart alarm,” you can set the time period when you want to wake up. GoBe will monitor your sleep, identifying the REM phase closest to the time you’d like to wake up at.

You can also use the “Quality alarm” for weekends or vacation time–GoBe will wake you only once you’ve achieved your desired “Sleep quality.”

GoBe automatically measures Sleep duration as the amount of time you spent sleeping between 9 PM and 12 PM the next day, excluding all the time slots you woke up at throughout the night.

GoBe identifies the time periods you spend awaken throughout the night. This stage is labeled in yellow on the graph.
Below the graph summarized wake-up duration and wake-up count is shown.

GoBe tracks your involuntary behavior throughout the night by measuring your physical activity and pulse changes during a sleep. It is a complex measurement that factors in the intensity and number of such uncontrolled movements, as well as any changes in your pulse.

GoBe monitors your sleep quality from the moment you fall asleep to the moment you wake up. An involuntary behavior level, sleep phases, and occurrences of being awaken are all factored into the quality of your sleep.
Sleep quality results are displayed as follows:

• 0-45%—a very bad quality of sleep
• 46-60%—some sleep disorders
• 61-75%—lack of sleep
• 76-90%—a good sleep
• 91-100%—a very good sleep

A recommended sleep duration for you tonight. The recommendation is based on how long you have been sleeping on average for the last 7 days, along with your physical activity and stress level during the last day.
