Apple - Watch Series 6

I’m not as hardcore as you. Doing fairly intense, compared to the average 71 year old, but I do exercise very rigorously for over an hour everyday. I’m tracking what is happening especially for endurance in improving general health and stamina. I do pool exercise and needed to have a watch that could last 6 to 8 hours per week every week. I went through my Series 6 with 5 replaced watches (I kept AppleCare) every year. So the Ultra Series has better water redistance and battery life. In can appreciate your comment about heart rate. I have seen problems with outlier measurements. There are one or two times, very intermittent. I’ll get a recorded heart rate reading about double the rest of the recorded HR. My anecdotal observation is it tends to happen in the pool. If I see the reading I will tighten the bad a bit and it doesn’t seem to continue. This happened on my old Series 6 and it has happened on my Ultra 3. It probably comes down to the intent of the design combined with the use case. If I go to my doctor every office visit begins with vitals being taken. It’s a snapshot in time. If a reading is about of whack they may repeat it in a few minutes once or twice, another slice of time. All Apple Watch products are really good at monitoring trends over time. You can setup alerts snd there are apps that can do additional analysis using the collected data. I look at trends events there too low and too high. The outliers do not really impact trend data. The other thing about trend data is knowing when your trend data occurs. I had a heart rate that would go below 40 bps in the 15 to 30 minutes before I wake-up in the morning. I got an alert that I was able to tell that to my Primary doc and Cardiologist. They suggested a change that needed to monitor for another couple of weeks. In my use case, the heart rate monitoring capability is 100% effective. It’s so effective I have the entire days HR data displaying in a compilation a full view of yesterday’s data and to date of the current day. Tap the graph and I can drill into the data, even the outline events. I’m not sure if the watch face comes from the heart health app I have or it’s in the Apple Watch stock watch faces. I have been enrolled the multi-year Apple Heart & Movement Study. The study has found that the Apple Watch sensor is accurate to within 5 bpm (beats per minute) for 98% of the time when users are in sedentary (or resting) mode, and reaches 99.7% accuracy with an error margin of 10bpm. The sensor’s heart rate accuracy varies: * 96% for outdoor cycling, * 87% while walking, * 88% while running, and * 91% during high-intensity workouts, with a 5 bpm error margin when recording in the foreground. Starting with the Apple Watch Series 6, accuracy has improved significantly. * Data from 480 participants logging 21,000 hours shows 89% accuracy (within a 5 bpm error margin) in the background, compared to 72% in older models.

The only consumer health tracker on the planet that is reasonably accurate enough to even think about maybe, maybe, maybe, deigning it as something which could monitor abnormal cardiovascular medical conditions, is the Apple Watch. Maybe. Even that's a stretch. Most trackers are very clear about how their features are only validated for otherwise healthy individuals. And the Whoop's EKG, as one example, barely even works for healthy individuals, let alone unhealthy ones.

Bevel (and Athlytic) are mostly pretty pseudoscience. The issue the Apple Watch has is that third party apps do not get access to low level AW sensor data; they only get high level summaries of the data, so they get "average heart rate over the last minute" instead of each intra-beat timing. This, combined with how the AW only takes sensor readings every five minutes, severely & negatively impacts the accuracy of Whoop-like statistics on that platform.

I use it for my workout. Its great, it has also greatly improved over new versions for tracking the meters better. I would never consider switching, most likely will get a new one in a year or 2. I also use it in open sea training.

I just switched from an Apple Watch (3.5 years) to a 255. I run and was mostly using my aw as a running watch. As a running watch it was fine, but the battery life sucked and my gps/distance was always a bit off from my friends. I’d much rather a slightly better gps than a slightly better hr sensor. Also, big, physical buttons are also great when doing things when you are sweaty. I didn’t even bother getting a touch screen. From my perspective, I couldn’t find a good reason to buy another apple.

I found I couldn’t use my AW for sleep because the battery was forever needing to be charged

I use both. I feel my Apple Watch is more accurate with HR, steps, workouts. My ring is for sleep and stress.

yea i wear both aw on the left whoop on the right. they are both good for different things and having the whoop gives me some peace of mind about my apple watch charge like i don’t stress about if it dies cause ik the whoop is running

Yeah I have taken fitness pretty seriously over the last 1.5 years. Have done 6 triathlons and feel that the Apple Watch is severely lacking. But I feel there would be too many trade offs to go to garmin

The expensive ones aren't any more accurate than the cheap ones, but they do last longer. I'm on my third Apple Watch and likely will never switch to anything else, so take my advice with all the weight of a single grain of salt.

Apple Watch every time. Allows me to control my iPhone on the floor or outside if I want to switch tracks or start stop my timer. No issues so far.
