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 8 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 (on devices running watchOS 8), 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.
-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

Terms of Use:

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.

If you have any questions we will happily help you:

Biggest complaint is that you can only add tags and ratings the day of! It would be extremely helpful to go back and add tags after the fact, especially for data taken before you started using the app. (Also REM detection would be great, and an explanation of what makes different measures red/ yellow/ blue.)

Developer Response ,

You can now add tags and ratings for all available days (please update Sleep Details to the latest version). REM detection is also if you update your Apple Watch to watchOS 9. Please note that sleep stage data will be available only for nights after the point you have updated to watchOS 9. Let us know if you have any additional questions or comments. You can contact us at

Great sleep tracking app

So I’ve been finding ways to get more thorough information on my sleep since I have insomnia and it’s hard for me to maintain a sleep schedule. Most sleep tracking apps have a subscription model service which I kinda find tedious if it’s going to be something that I would need long term. There are a few things on those apps that you don’t find here, other apps do feature other things such as music that you can play to help make you fall asleep. REM sleep tracking which really doesn’t mean much to me, and maybe other features such as snore or voice detection while in bed.

Those 3 features don’t matter as much because the price of this app is WAY cheaper than the other sleeping tools that are out there. While other developers try and tack on a subscription model, this app is only $4 for the lifetime edition. Only $4 and you get to analyze and compare data really easily. It does everything that I would need it to and I would like there to be a tip option, and if any dev sees this. I’d like to request a few things. A tip option would be nice for other people who would like to tip anything extra for the price, maybe also REM sleep tracking if that could be implemented. Any other features would also be nice.

Developer Response ,

Thank you so much for your review. We will keep adding more features to Sleep Details on a regular basis. Even though pricing options for Sleep Details will probably change later on, users who have purchased Lifetime Access, will always have access to all features available in Sleep Details.

Not too happy

I noticed that it doesn’t always pick up on when I am sleeping like my Fitbit did which is disappointing. There also is not much description on what your sleep score means…or what they are basing their rating on so you can see if you need to improve or why did I sleep well and it’s saying I have a 56 score? This area definitely needs improvement consider how much you pay for the Watch and their competitor Fitbit does better in this area.
