The Sleep Graph is a linear progression of your sleep over the course of one night. Only Zeo allows you to see what stage of sleep you’re in and when at a given point during the night.
The color-coded segments each represent a different sleep stage: Wake is in red, Light Sleep is in gray, REM sleep is in light green, and Deep sleep is in dark green.
On the left side of the chart are the following stats:
Another helpful feature of the graph is that it includes a pie chart that breaks down your sleep into percentages and time increments. This is helpful because it lets you see how much total time you spent in each stage of sleep and how much each stage contributed to your total night of sleep.
