## What is Sleep Details?

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

Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula

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.

### 2/5 — Too basic

*2026-08-12*

The data being tracked is very limited and no description of why your overall score is rated as it is. You can’t export the data so I’m not sure what I’m supposed to do with data captured in a single app that I can’t analyze. Also, it greatly varies to sleep scores as reported by Apple and when I get a low rating, I actually don’t feel terrible so I don’t trust it’s algorithm.

### 1/5 — Bye

*2026-03-23, version 5.1*

Claims a free trial, the sole way to test features. But Apple’s popup lacks “free” language ALWAYS appearing in every other circumstance a free trial is actually on the table. If you’re not paying attention, you’ll get snickered. Deleted, with dev added to my NEVER! List.

### 3/5 — Recent update or what?

*2025-10-01*

Honestly I loved using this app for months now. It kept me on top of my sleep and I loved the fact it would score it. 
Recently, idk if it was an update or what but I can’t even add my supplemental sleep anymore. 
Because I take naps here and there or sleep past alarm lol. But it won’t even allow me to add them anymore. So I’ll be just going back to apple health because at least there I can add it.

**Developer response:** Thank you for your feedback. You can enable the Add Nap button in the settings section of Sleep Details. If you have any additional questions you can contact us at contact@sydvesti.com

### 5/5 — This app is the best!

*2025-07-18, version 4.4.1*

This app really helps me understand how sleep affects my health!

### 5/5 — Muy interesante

*2024-12-16, version 4.1*

Muy positiva

### 4/5 — Have you changed the app?

*2024-12-12*

It seems that my sleep scores have suddenly improved and I know I’m not sleeping any better than I used to. I have a chronic health issue that causes sleep disturbances. Have you changed something in the app?

**Developer response:** Thank you for using Sleep Details. We haven't changed the score calculations. It could be that one of your metrics such as Hear Rate during sleep has improved compared to the comparison baseline (7 day RHR). This would improve your score even if your sleep duration etc hasn't improved. You can open the History section to see if one of your key metrics has improved compared to your long-term averages. Please contact us at contact@sydvesti.com if you have any additional questions

### 5/5 — Sleep Stage Section Disappeared

*2024-11-07, version 4.1*

Update 11/7/24: issue only occurred on one night and has resolved itself since. 

The section with Awake - REM - Core - Deep has disappeared. It’s there for all of my past day graphs but not for today. This was one of the main reasons I purchased it. What happened? Why is it gone?

### 5/5 — Sleep Stage Section Disappeared

*2024-10-26*

The section with Awake - REM - Core - Deep has disappeared. It’s there for all of my past day graphs but not for today. This was one of the main reasons I purchased it. What happened? Why is it gone?

**Developer response:** Sorry to hear that sleep stage section was missing for that day. Probably for some reason your Apple Watch just hadn't recorded sleep stage data for that specific day. Could you contact us at contact@sydvesti.com so we could try to figure out what caused the issue.

### 2/5 — App problems

*2024-09-07*

I’ve had this app for a few months now and I’ve already paid for my subscription and then wants me to pay another month now. when I’ve already paid for it through my Apple billing this is causing major inconveniences

**Developer response:** So sorry to hear about the billing issues. Could you contact us at contact@sydvesti.com so we could figure out what is causing the issue. Could you also check if the subscription is listed correctly here: Open Settings on your iPhone > Tap your name / account > Select Subscriptions. So sorry for the inconvenience.

### 1/5 — App keeps kicking me out

*2024-07-24*

I'm having a frustrating experience with this app. Whenever I give it access to my health app, it kicks me out every single time I open it. I was really looking forward to using it to track my sleep and get detailed information, but I haven't been able to use it for that purpose. It's really frustrating and disappointing.

**Developer response:** So sorry to hear that the app isn't working as it should on your device. Could you contact us at contact@sydvesti.com so we could figure out what is causing the issue on your device.
