It's interesting these devices seem to be getting worse when you'd expect them to get better. I guess they're all trying to outdo each other with features to keep the sales flowing, assuming that most people don't know (or care) that accuracy is being sacrificed. For many people, I think it's probably not that much of an issue; but for those, like you, who rely on monitoring for high-level training, or those of us using devices to try to help us navigate and manage chronic illnesses, it *does* matter. Ah well, I guess 'jack of all trades, master of none' comes to mind here ... 😏

Thanks for this Marco. One thing I’m still not sure about: with the concerns over accuracy, are you referring to just the Apple Watch HRV values above, or also the RR intervals stored in Apple Health alongside the HRV data?

Bottom line, should I stop using the Apple Watch for my morning HRV measurements with HRV4Training?

thank you Thomas. Indeed it is unclear how often these things are changing and what is their impact. If you have no issues with using the camera, maybe I would give that a try as it’s something where we have more control.

I’ll try taking both for the next week or so, and see what, if any, difference I see. Will report back (even if it’s only one datapoint!).

Thank you for this. I have been wondering how accurate my Fitbit is, and now I see another way to check HRV. I’m not an athlete… just a 58 year old woman trying to see my health trends accurately. Thanks!
