Apple Watch in JAMA Cardiology

[Thai]

Here's an attempt ... Apple HR performance rocked in the study against a couple direct-ish competitors. But, I wish I knew how it stood up against the other leading competitors, like the vivosmart HR, Jawbone UP3, Gear Fit2, Mi Band, Microsoft Band 2, Polar Loop, etc. My AW has been fine for me, but I am curious where it ranks against the rest of the field.

But, if you look at data, then it is still impressive bc Watch's heart rate was very accurate to an ECG. Does it matter if they did not test the newer units? The facts of the study make Apple Watch to be very accurate when compared with the medical standard (medical grade ECG).

The study did not compare Apple Watch with Mio...if so, then i see your argument. But this study compared Watch with ECG. And Apple Watch scored amazingly well, regardless of who else was in the study!!!!

I hope that your realize how silly your theory is now.

That would be a great test. I can't tell you how many times people have complained and backed it up with proof that the Apple Watch fails for them. I can't get mine to fail more than once or twice in a workout and since version 3 - even better. I can golf in the heat and humidity and still not lose a reading.

Now to really test as I wake to mid 20 temps already. The old version struggled at the start.

Exxxviii offers great content and information on fitness and other devices. I really think you are missing his points as he isn't a watch hater.

Yeah, mine had a very tough time in cold temperatures until the AW and I warmed up together. I am curious to see if this is any better with wOS3 this winter.

I understand his point 100%. But he is missing the point of the study. REGARDLESS of who was in that study, Apple Watch did extremely well in matching with THE STANDARD (ECG). This study was NOT about comparing Watch directly with other tested device. The study compared these devices with a standard that is 100% accurate. And Apple Watch PROVED that it was extremely accurate against THE STANDARD.

This is great, but the caveat is that the more active you are the less accurate the HR sensor is, markedly so from what I read and also experience myself. I think it's important not to miss that point because it seems some are taking this to mean the Apple sensor has this accuracy in all situations, when it's just as crappy as the others once you start having higher activity levels. I'm not sure if they defined where the accuracy drops off, but I'm curious if they did.

The study did say that none matched chest strap. But 2 out of 4 were not accurate at all during moderate exercise...Apple Watch not being one of them. So, we need to give credit to where it's due as well. Apple Watch got a Concordance Correlation Coefficient of 0.91, which means that the results noted in study is reproducible and reliable. And this, again, has nothing to do with the competitors in the study since all were compared against the golden standard.
