this is kind of a trivial question but is the apple watch HR monitor known to be better than that of FitBit? I got a Charge 3 for Christmas and I barely even wear it anymore, as it would say things like "95 bpm" when I'm working out and I'm clearly at around 135 bpm. you can say things like "oh wear it higher / lower / tighter" whatever but if it's that prone to being 40 bpm off the mark, what use is it.

I can see a future where my doctor gives me a wristband to wear for a month then return as a part of each annual checkup. Though maybe it gets even better than that and we just all start wearing watches again. I want that feature but I'm not a watch wearer.

The future is your insurance company making you wear a smart watch 24/7 if you don’t want to pay a huge premium. I predict it’s going to be a huge quagmire over the next decade or so.

It would be a huge invasion of privacy for an insurance company to do this - and not only privacy, but the fact that insurance companies can discriminate based on this data means that the healthy don't end up subsidising the unhealthy (which is the whole point of insurance). SO premiums go up regardless, and only the insurance company win in this scenario.

Right now, the right choice is to combat this problem before it becomes a real problem. Before it sets root as cultrually acceptable to hand over your biometrics data to private companies without the right payment and compensation.

I work at a related company (Cardiogram), and there's a surprising amount of signal locked in the humble heart rate sensor -- we've run multiple studies with UCSF showing accurate detection of sleep apnea, high blood pressure, and even diabetes using off-the-shelf heart rate sensors and a deep neural network, DeepHeart: https://blog.cardiogr.am/screening-with-wearables-what-do-th...

Earlier quoted context omitted.

Are you advocating that we shouldn't bother testing instead? I'd imagine that many people would be quite interested in knowing the ways they're not 100% that might actually kill them... like cancer.

It's complicated... Not all instances of cancer are harmful, more men die with prostate cancer then die because of of it and thyroid cancer is found as an incidental in ~30% of autopsies. More detection can cause more harm than good, as what happened in South Korea with thyroid cancer screening, a huge increase in detection and treatment without any decrease in survival rates. Here's a good overview: https://scienceb…

Under-rated opinion - if you're not feeling ill, there's probably no reason to perform any medical diagnostics. If you're wearing a medical diagnostic bracelet, and it tells you that you have some issue, you might end up getting more anxcious and stressed (which can cause real harm), despite the fact that there's nothing "wrong" really.

One-off comment, but the new band has really improved HR detection for me. I went from the rubber strap (with holes every centimeter or so) to the adjustable velcro strap and it's night & day. It went from being 100% useless on runs to _actually_ keeping accurate detection the entire run.

I saw a few posts on Reddit about how the Apple Watch basically saved people's life: https://www.reddit.com/r/AppleWatch/comments/a40qm5/heading_... https://www.reddit.com/r/AppleWatch/comments/9zrdq5/how_an_a... I'm sure there is a lot more. (Also all the people losing weight)

I wish there was a heartbeat-measuring watch with the battery life of a dumb watch. My watch goes like 5 years (I've lost count honestly) on its original battery. I'd love to have something watching out for my health but I just can't see myself moving to a smartwatch that needs recharging every 18 hours when I don't even need the smartness crap...

My cardiologist has looked at it when I'm hooked up to a full 12-lead EKG and has noted how pretty solid the measurements seem to be. If it's on a slightly looser setting, sometimes it initially catches only half the tempo for a second, but then locks in. This is on an Apple Watch 4.

In my experience, FitBit Charge HR 2 was useless. Same issue with you where it would 40 bpm off or provide no reading at all.

Apple Watch 3 was pretty bad too. It would give inaccurate often enough that I couldn't use it for training in a heart rate zone. For example, I'd be walking for warm up and it would give a reading of 160 at the beginning, then back down to 110, then 10 mins later back to 160. I can't imagine the Apple Watch being a medical device with lives depending on it.

Garmin 935 has been great. It has the most accurate HR and GPS readings.
