Sleep HRV – An app to record true (overnight rmssd) HRV from the Apple Watch

In settings if you tap “Check intervals API” are you getting a green dot appearing?
And is there nothing else writing to the “Avg Sleeping HR” and “HRV (rMSSD)” fields?

Also if you Sync last 28 days does it manually sync?

Green dot? - Yes.
Nothing else writing.
Manual sync - works fine.

Just checked now and today’s is there so maybe it’s sorted itself. Will send report through app if not. Thanks.

Version 0.6 should now be available (yes v0.5 was skipped).

0.4 had zero crashes, so worked on a few things that had been in the backlog a while:

  • Sample filtering had a minor tweak and there should be almost zero high outliers. Refresh your data back to a chosen date and you’ll see any high outliers back to normal.
  • If you still have high outliers you can now hold the date and select “Hide Day” and that days data will not be included in any charts or calculations.
  • Tapping the date will now toggle more detailed data - including min and max HRV and RHR, actual time asleep, number of wakes, total samples and filtered sample count.

The app is adding the sleep duration to the time spent in bed. Can this be fixed? I only want to see the sleep duration.

Thanks so much. I did the 28 day refresh and seem to have lost the graph. I think the data is all there.

OK that’s a curious one! Can you try refreshing data back past the current earliest record? Something is weird back in the history I think.

Is this happening consistently?

found the issue, had a rogue v high day that I hid and its now back to normal - thanks

This looks great - I’d like to test it out! Wil you please send me the Test Flight invite?

Do you know if your algo removes hrv readings when the watch detects you are awake in the night? Is it linked to stages. Ie get up in the night and hrv increases will that skew your data?

Also any reason sync needs me to open the app twice or click at the bottom. Is it not automatic?

It filters out any measurements made while you’re awake, include short wake phases during your sleep.

Have you got “Background Refresh” enabled in the settings? If so it should be doing background refresh of the data?

Thanks for the link! Probably a dumb question - but where do I find the settings for the app?

Sorry, onboarding is still on the todo list. Double tap in the white area down the bottom of the screen.

Hi. My app has expired. Is it no longer in test flight? Thanks

+1 Expired app. Next steps? Cheers

Hi folks - apologies, the latest version has been in App Store review for a few days now. Hopefully in the next 24hrs it will be through and you should get the update.

Also if anyone is getting any issues please do DM or post here. TestFlight is reporting only a very few crashes from the last release, so if it’s stable I might finish up onboarding and push to the proper App Store.
