The Oura App contains several graphs to help you track and interpret your sleep patterns, including:
- Sleep stage hypnogram: a breakdown of the stages of sleep you entered (awake, REM, light, and deep)
- Nighttime movement graph: how much, and when, you moved during your sleep
- Body Clock: a 24-hour clock face with color-coded sections to compare your optimal sleep window to your current sleep patterns
- Nighttime Breathing graph: shows suspected breathing disturbances during sleep
- Sleep timing graph: a vertical bar chart that shows your time in bed, time asleep, and any awake time interruptions during the night
You can also use an iOS widget to put the hypnogram on your Apple device's home screen.

How to Use the Hypnogram
A hypnogram is a graph of sleep cycles throughout the night. Your hypnogram can be found below the sleep contributors under Details in the Sleep detail view.
The number above the hypnogram is your "Time asleep." This is not the same as your total time in bed, which may include periods of awake time. For adults, it is recommended to get at least seven hours of sleep each night.
Sleep cycles typically consist of ~90 minute groupings, each containing some amount of light, deep, and REM sleep. Sleep varies from person to person, so a sleep cycle may not always have all three stages, and may not always last 90 minutes.
The average amount of time spent in each sleep stage is:
- Awake: 2-5%
- Light: 45-55%
- Deep: 13-23%
- REM: 20-25%
If you export your sleep stage data from the Oura App to Apple Health, your sleep stages graph may appear differently.
The Oura App hypnogram displays sleep data using five-minute intervals, optimizing for readability while still accurately reflecting sleep stage trends. Apple may apply slight rounding or display sleep graphs using different time intervals, which can result in variations between the two views.
How to Use the Nighttime Movement Graph
The nighttime movement graph is located directly beneath your hypnogram.
Vertical lines on the graph each represent five-minute increments and correlate with movement in your sleep—the more movement, the taller the line. Short lines can indicate tossing and turning or general restlessness. Tall lines may correlate to times when you were awake. Compare your nighttime movement graph to the hypnogram to see which sleep stage was associated with the amount of motion.
Continuous restlessness can lead to delayed sleep detection, an inaccurate bedtime, or missing sleep stage data. The ring may interpret continuous movement and elevated heart rate as wakefulness, even if you were technically still asleep. Read our blog post about Restless Sleep.
Very low movement typically correlates to long periods of deep or REM sleep, a good sign of high-quality rest. Learn more about nighttime movement on our blog.
How to Use the Body Clock
Your Body Clock card will tell you how closely your sleep rhythm's midpoint from the night before was aligned to the midpoint of an optimal sleep window, as determined by your chronotype. If necessary, the Body Clock will provide guidance on how much to adjust your sleep timing in order to align with your circadian rhythm.
The Body Clock card can be found by tapping on the sleep shortcut at the top of the Today tab, then scrolling down.
Tap the Body Clock card to open a more detailed version.
The outer ring of the clockface indicates your sleep schedule from the night before. The inner ring is your optimal sleep schedule based on your chronotype. You can use the Body Clock to see at a glance how closely the two schedules are aligned.
Tap the info ⓘ icon in the upper-right corner of the app for more information on circadian rhythms. Tap the chronotype description at the bottom of the Body Clock screen for more information on your specific chronotype.
How to Use the Nighttime Breathing Graph
If there are suspected variations in your oxygen levels during sleep, which may suggest breathing disturbances, they’ll appear as bars on a timeline. Each bar represents a 15-minute window, spaced at 15-minute intervals throughout your sleep.
The height and color of the bars reflect how often these disturbances occurred, from few to occasional to frequent. Together, these nightly readings build up to shape your prevailing pattern over the 30-day window.
Instead of focusing on one night, keep an eye on your breathing regularity trend over time.
Starting June 16, 2026, Nighttime Breathing will be updated for members in the US, the UAE, and India in English only. Members in these regions will also be able to see prevailing patterns across a 30-day window. This update is rolling out gradually. See Health Radar for more on Nighttime Breathing patterns.
How to Use the Sleep Timing Graph
Sleep regularity is a Readiness Score contributor that measures how consistent your bedtime and wake-up times have been. In the My Health tab or the Trends section of your Oura App, you can find data visualizations of your sleep regularity patterns by day, week, month, or year.
Below the sleep regularity trend chart is a graph of your sleep timing, which shows your time in bed, time asleep, and any awake time interruptions during the night.
The sleep timing chart represents the consistency of your sleep as vertical bars. The time you went to bed is at the top of the graph, with wake time at the bottom. Time in bed is visualized with a faint, dark blue bar. Time asleep is visualized with a solid, bright blue bar. Any interruptions to your sleep during the night appear as gaps in the bar.
Scroll left and right to see more data. The y-axis of the chart is fixed to your median sleep time plus two hours. Any data outside that time, such as a very early bed time or very late wake up time, cuts off at the upper or lower edges of the graph.
Weekly, monthly, and yearly views of your sleep regularity trends display averages of your sleep timing for those time periods.
How to Use the Hypnogram Widget
There are three available iOS widgets (small, medium, and large) available to display the most recent night of data on your device's home screen. These are available to Oura members using iOS devices and any generation Oura Ring.
The widgets display:
- Small: sleep stages
- Medium: sleep stages and sleep/wake time
- Large: sleep stages, sleep/wake time, and ring battery status
To install a sleep graph widget:
- Touch and hold your device's home screen
- Tap the Add (+) button
- Select a widget and widget size
- Tap Done
Things to Keep in Mind
Oura Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. Please do not make any changes to your medication, nutrition, or workouts without first consulting your doctor or another medical professional.
Every body is different. Instead of trying to hit specific numbers, keep an eye on changes in your data compared to your baselines and overall trends.
Make use of tags and trends to see what factors may be impacting your sleep.
