I think that most folks know that chest straps or manual HR measurements are the most accurate, especially the athletes. But, these threads are revealing that fitness tracker customers want a device that gives them regular HR readings. And based on the comments, it looks like those users can live with some inaccuracy. Additionally, there are other threads where AW users are reporting that the watch measures very closely to their chest straps during exercise, so maybe AW is using a good sensor. I plan to run with my AW to compare it to my Garmin. I am very curious.The most accurate way to track your HR while physical activity is a chest strap or taking your pulse on your neck or wrist for 10 seconds multiplied by 6.
The actually makes a lot of sense... Resting heart rate is more important than heart rate while you're walking down the street. I would be more interested to see how my resting heart rate changes throughout the day. You still get you heart rate when you workout and you can always manually check it. Battery saving or not I think this is pretty smart by apple.
One more thing: Resting Heart Rate ≠ HR when Arm Not Moving
This change does nothing to improve a resting HR measurement. The watch was already capturing a resting HR just fine. It is causing the watch to ignore a lot of readings throughout the day that people might find informative.
Heart rate-gate.
Continuous heart rate monitoring never made sense to me from a fitness tracking perspective so having that go away with the watch update doesn't seem like a problem. Heart rate monitors were designed to measure effort during steady state aerobic exercise. Equations that estimate calorie burn using heart rate are based on certain assumptions that just don't apply to other types of activity. So if people are concerned that not having readings every ten minutes means your calorie burn is off, well, HR wasn't going to give accurate results outside of a cardio workout situation anyway. I suspect Apple is relying on other estimators for basic daily movement (they should be if they aren't), and only relies on heart rate when you log a workout.
I do realize there are other valid reasons to want to monitor your heart rate, so giving people the option to log HR data regularly outside of a workout would be a nice option. Just wanted to say that it doesn't matter all that much for calorie burn in non-cardio-workout situations.
Why is it that important you get a reading every 10 minutes? If you are that unhealthy and worried about your heart rate, go see a doctor.

I'm pretty sure it still tracks activity.It's false advertising... it was sold as checking your heart rate every 10 minutes... now it only does so when you're not moving? so this fancy "activity" tracker can't actually track activity but only "inactivity" hmmm.... someone dropped the ball over there.
Yeah, I figured people would disagree. Again, my comment was that if you want continuous HRM for calorie burn estimation, be aware of the inherent limitations on accuracy. Heart rate can go up for a variety of reasons and the corresponding effect on energy expenditure also varies. Those who are interested can google HRM and weight lifting for a variety of articles on how HRMs do (or don't) work for estimating calorie burn during strength training, as an example. or check out these blog posts (not first person research but nice summaries of the factors involved)Disagree .. So do Fitbit, Basis, and Microsoft. All use continuous HR monitoring to better gauge activity. If the HR sensor is present in the watch, then why not utilize it.

The most accurate way to track your HR while physical activity is a chest strap or taking your pulse on your neck or wrist for 10 seconds multiplied by 6. The watch can do it for you if you manually do it and log it. You guys talk about being active and use it for fitness but are too lazy to manually log it? Burn a few calories by lifting up your arm and manually take your HR. Sheesh!
In one of the online reports I read on this subject Apple was saying that they did this to improve the HR reporting. I believe that more than battery life, which will be improved by this change, is the fact that Apple was seeing a lot of reports of people complaining that the system was wrong because they were seeing wildly varying numbers for their HR. Invariably others would ask if they were possibly moving around at the time when the increased HR was recorded. Apple does not take lightly reports of their equipment not being accurate when the cause is people not using it correctly or not interpreting correctly. I see this as their way of ensuring that the HR is only measured when the Watch owner is sitting or resting thereby insuring that "erroneous" readings do not occur.
I do wish, if this is the case, that would have set it up so we had a choice: take the HR every 10 minutes or when sitting.
