The new Oura ring starts to collect data from you immediately after you’ve paired it with the Oura app and put it on your finger. So, you’ll start seeing data about your activity during the first day of use, and data about your sleep and recovery after the first night of use.
During the first day, what you see on your app main timeline is your accumulated activity during the day. It's shown in calories. You'll also see your inactive time during the day in hours/minutes. The app shows you an activity goal for the day, again in calories. The number is based on an average activity goal for a person of the same age, gender, height and weight as you.
On the first morning, what you'll see is your first readiness and sleep scores. The main timeline also shows your sleep timing and lowest resting heart rate from the night, and your activity goal for the day. You can dig deeper into your readiness and sleep data by clicking the readiness and sleep cards. You'll see more insights and data about your sleep and your body signals: your sleep stages (light, deep, REM and awake time), total sleep time and bedtime, resting heart rate, heart rate variability, and nocturnal average respiratory rate among other.
Note that some of the insights Oura will start giving you (readiness score among other) require that the ring and app learn a bit more about you. It’s because guidance related to your recovery requires data about your normal baselines, such as your normal nocturnal body temperature and most common wake-up time.
In practice this means that during the first weeks of use, Oura starts to collect your baseline data, and before your baseline is fully established, some of the guidance is based more on averages for a person of the same age and gender as you. As time passes, the guidance you’ll see will get more and more personalized. Also the trend views will become more and more informative, as there’s more data to show. Just remember to wear the ring very regularly (if not all the time)!
If you happen to be sick during the first weeks of your Oura life, or your daily rhythms are otherwise abnormal during that time, it will show in your baseline data for a while. It will take a couple of weeks for the ring and the app to learn your normal values, such as your normal nocturnal body temperature.
