Each bar will give you details of REM sleep, awake time, light sleep, deep sleep.You will also see another graph that will give you a visualisation of total sleep, disturbance, sleep latency, and sleep efficiency. You can also compare the data day-by-day and check the resting heart rate variation over the week.All the data is stored in the Oura cloud that you can easily access if you want to check the data outside the app. In the Activity category, you can see a visualisation of data such as steps and daily activity burn.The app also lets you know how ready youre for the day based on your previous nights sleep quality, your resting heart rate, body temperature, and recovery index.
