Sleep Details integrates with the Health app and uses data stored in the Health app. Key features: -Daily sleep score based on sleep duration and other relevant sleep related data -See details of the following sleep related data: Sleep stages and times, Activity while sleeping, Heart rate, Heart rate variability, Respiratory Rate, Blood oxygen levels (SpO2 data is available only on Apple Watch series 6 or later devices), Wrist Temperature (only available on Apple Watch series 8 and Apple Watch Ultra devices ) -Privacy: We do not collect any data from your devices -Receive morning notifications with last nights sleep score and sleep duration -Rate your sleep.

To highlight this, we added a simple memory test in Sleep Details: 1) Before going to bed try memorize a set of icons and their location. 2) Then after waking up, try remember and fill in these items. 3) New icons and locations will be generated for each day, so you can track your long-term progress by completing a new test each day. -Add Sleep Details as a complication on your watch faces -On your Apple Watch you can tap different metrics to see more details -Two week sleep score trend available on your iPhone.

As an example your score will be lower if your last nights heart rate average is higher than your weekly resting heart rate average. In this case the heart rate ring will be colored red so you can easily spot which metrics are negatively affecting your score. If you have any questions we will happily help you: contact@sydvesti.com
