Seems that some days it doesn't take a reading. Breathe app doesn't seem to work either (read that it used to).

Any ideas?

Why would you open the heart rate app. It doesn't record HRV o_O

There is no (known) way to 'force' a reading. Went through a few days on mine and get from 2 to 10 readings a day and it displays the highest reading. Have you looked to see if it is taking the readings in Show All Data in the Health app? Here is a single reading point from mine.

If so have you tried a restart of both you Watch and iPhone? Next might be to try a Un-Pair and Re-Pair.

It did for me, not sure what you are looking for then. ;)

Oh... Humvee Racing Value? No, no, it doesn’t record that!

Cringe. No clue at all :rolleyes:

Julien, yes I've been trying to 'hack' it like that too. Messing around with pairing and charging. Just can't find a way to force it to take a reading.

Usually I'll get two readings a day, but some days just nothing. I have readings going back to November and it seems to have always been like that. Some days it just doesn't read.

Just recently taken an interest in comparing the numbers to performance management charts (ie. form/fatigue/fitness) on Xert, TrainingPeaks and other software. Thought it would be interesting to see if there's any correlation. Would really need daily readings though as form changes dramatically daily depending on training intensity, so I'm not looking for some sort of 'general' trend right now.

I feel like HRV is an afterthought, quickly tacked on, for the time being. But hopefully Apple will improve usability soon. Maybe even provide some sort of analysis from it if they get confident enough with the data and algorithms.

There are now a couple of apps that will measure. Go to the Apple Watch app and then App Store and type in HRV.

I see HRV Watch and HRV Score. You do have to have a Series 3.

You are conflating or confusing HR (beats) with Heart Rate Variability. They are 2 VERY different metrics. Here is a good article to understanding what HRV is.

Ah, good point. Thanks for the pointer. Did you see that HRV needs one minute of data? And that readings may be influenced by activity?

For the OP, it seems you will need to be idle and keep relatively still for a minute for the reading to succeed. Looking at my data, I do have readings almost every day, but usually between 1–4 readings. The times seem to be somewhat random. I suspect the Watch only attempts the reading every hour or half hour. If you are extra active or the data looks bad, the reading is probably aborted.

Edit: I was just able to add a HRV reading with the breath app. Maybe it only works in some cases? I used a 1 minute setting. Watch model watch have people tried?
