Track your sleep related data and see your daily sleep score based on data collected by your Apple Watch.

Sleep Details requires an Apple Watch with watchOS 10 or later installed. 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. Your personal feeling based rating will also adjust your daily score
-Tag your sleep with factors that possibly affected your sleep. For example if you feel that caffeine affected your sleep you can tap the caffeine icon to tag your sleep
-Add naps: In the iPhone app you can add naps that Sleep Details has detected. You can also add naps manually. Your naps duration will contribute to your daily sleep duration and therefore affect your daily score and sleep dept calculations.
-Night Mode: If you open Sleep Details during the night, you will see your most recent 4 hour Heart Rate, Heart Rate Variability and Blood Oxygen (Series 6 or later) averages.
-Daily Sleep Summary: Devices that support Apple Intelligence can use the 'Generate summary' feature to generate a daily sleep summary with additional insights (iOS 26 required).
-Sleep has an important role in the performance of your memory. 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. You can tap different days to see the sleep details of the selected day
-On your iPhone you can tap different metrics to get a description of the selected metric
-History view with your all-time averages and min/max values for all available sleep related data
-After your free seven day trial has ended you can continue to use the app by purchasing monthly subscription or the "Lifetime access" in-app purchase. Purchases can also be made before the trial ends by tapping the trial end date. 
-"Lifetime access" and monthly subscription purchases will also unlock the Sleep Details toolbar and comparison charts

How are different health metrics used to calculate your last nights sleep score? 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.
