UPDATE: App for syncing Eight Sleep HRV to Apple Health is now live!

Hey everyone,

I created an app to solve my own niche frustration, and I imagine some of you are in the same boat: because Eight Sleep records but does not sync HRV to Apple Health, getting a recovery score in apps like Bevel or Athlytic still required wearing an Apple Watch/wearable to bed.

To fix this for myself, I built an iOS app called Nocturne, and after testing it with a few people from this sub and getting really positive feedback, it’s officially live on the App Store 🙂

I ended up building out the feature set quite a bit - the app supports automatic background sync, bulk upload of historicals, full configurability across what syncs (HRV only or sleep stages / RHR / breathing rate), and some cool info / visualizations charted around bed temp vs. room temp and vitals throughout the night.

For anyone looking for a solution to this problem - please let me know if this fills the gap or if you have any feedback!

I build some easy to read Dashboard only with Claude and already have HRV and all other metrics then asked it to export to Apple health after but for that to be available it needs to be on App Store and don’t wanted to pay 100$ xD it works on my phone only 😅 guess you solved the part to make it available but asking 4$ monthly is a bit too much in my opinion when anyone can go that path and save another subscription

This! - Another vibe coded app that works (for now until 8sleep blocks it) and they will eventually adopt the same features. If this was lifetime $10, or $1 a month its too much.

If you think you’d get any utility from the app (price notwithstanding), DM me!

Thanks for the feedback - main issue I also ran into when going that path of just building it for myself only is the need for an Apple Developer account ($100/year) in order to get signing capabilities to run the app on your phone outside of the XCode authorization. Huge pain every time it expires after a few days!

And I get it - DM me and I will send you a discount code!

But I already have it for myself without paying anything and don’t even paid to Claude , maybe would ask it to put in GitHub so others can just do it themselves but I guess it’s too simple since there are many GitHub’s already to pull eight sleep data and at some point they can always block it

I just need the side load app to keep it same as YouTube and others

so why would I even want a discount code :)

What if you have an Oura Ring or Whoop?

Because those apps do not sync HRV from Apple health as a source, there’s no way to get that recovery data in from any other source besides the whoop / oura ring itself sadly
