In Intervals I get my total hours but no other details importing via HealthFit from Apple Health recorded on Apple Watch. How are others doing this with the new score and stages breakdown without 3rd party apps. Thanks
For Apple stuffs, you will need 3rd party stuffs. I believe the new Android health connect also needs 3rd party stuffs as everything will live on your phone/device and not in the cloud.
Yes. I think most use HealthFit just it doesnāt seem to populate in intervals
You could also use Apple Shortcuts with Automations. Itās able to GET POST or PUT any Rest API / URL. But not sure if Apple shortcuts can read any details of Apple Health Sleep States, it has access to Health, but never looked into the details.
ah yes.. there is shortcuts but thatās way too much stuffs for me to figure out.
Re HealthFit, youāre only getting total hours because the other sleep stages are Custom Fields within Intervals.icu and IIRC, that means that this is not natively supported.
You can give BreakAway a try, unfortunately its a 3rd Party App so it may not be what you want.
I support custom fields and thus the REM/Light/Deep stages are supported. When I did this support, Sleep Score wasāt something that Apple supported. Has this changed recently?

Perfect this works.
Any chance of adding sleep stages in your wellness? Thanks
I would take the sleep stages, on a wearable, with a pinch of saltā¦ sleep quality (subjective) and duration are adequate enough to pick up trends.
In order to truly get sleep stages, youād need to do a Polysomnography (PSG), and spend the night in a sleep study. Wearable devices arenāt accurate, and generally guesstimate the stages, leaving you making decision based on estimates from your device.

Ok thanks. What is optimal for readiness from an Apple Watch?. Iāve been using Athlytic app.
Make that a big bag of salt 
Sleep stages on wearables are based on parameters that āseemā to have some correlation to sleep stages. Best case is a 80% correlation factorā¦ Would you invest your money if you have 20% chance of loosing it?
The truth is that it just spits out random numbers.
Total sleep duration is not too far off and as @Gerald says, if you combine that with subjective sleep quality, you got all you need. The random numbers from your wearable risk that you take the wrong actions to correct in some way.

Iām using HealthFit as the link between my Apple Watch and Intervals. I only use the watch for limited activities and not health metrics, as I use HRV4Training+Polar H10 for HRV, resting HR, sleep duration (in bed time) and sleep quality, as well as the subjective scores like fatigue, soreness, stress, mood, hydration, etc.
I donāt sleep with the watch every night, but I do have the data if I want to have a glance at it weekly/monthly/bi-annually or annually. The Apple Watch sleep score is a good place to start, but it doesnāt sync to HealthFit (from what I can see). Itās relatively good, as itās checking if you have good sleep hygiene:
- go bed at the same/similar time each night;
- get a similar amount of sleep (time in bed);
- have as few interruptions as possible.

If youāre referring to REM/Light/Deep sleep stages, yes those are supported but as Custom Fields, you can refer to the above post.
Iāve been using this w Garmin data Syncāed to APple Health and then to Intervals.
w/ regard to sleep score, like what the others has stated in this thread, the last I read is that APple also regards that as pseudo science or such and doesnāt include/utlise that. Hence, I didnāt support it.

Iām facing the same situation, and Iām working on finding a proper solution. Iāve left the Garmin boat after 10 years and Iāve decided to rely on intervals as my health / sport platform.
At the moment I can tell you that haeltfit can export a lot of health metrics to google sheet , but just a few on intervals directly.
So decided to give a try to Apple Shortcut solution, and with some work you can get most of the metrics in intervals.
But last, the solution has been revealed just once Iāve decided to give a try to āAuto Exportā.
What I can tell you is that if you like to play with data , thatāa the third party service you need .
Iām working on a simple and āpersonalā solution that follow this flow
Apple Watch > Apple Health > Auto Export > CloudflareWorker > intervals.icu
What I can tell you is that it works , Iāve spent just a few time considering personal matters, but it works and Iām planning to finalise works by the end of Jan 2026
Here some examples
Feel free to ask for any info

I am using Health Sync. It works well. Works with lots of apps and syncs lots of metrics.h
Canāt see that adding score or stages
Thanks. Can you tell me more on how to do this?
Hi. I seem to have different sleep stage durations in intervals from Apple health using your sync. Any tips or suggestions. I used the same custom fields as per your instructions. Thanks
Some screenshots would be good before trying to get you to get some log.
-
data in Apple Health (take note that the data in Apple Fitness App is DIFF from Apple Health in some cases)
ā Apple Health ā Sleep ā Show Show All Data (This would give the breakdown of each sleep stage)
ā Take a few RANDOM days -
Data from Intervals
ā Same as the above random days
SleepSecs = REM + CORE + DEEP
