I use my series 2 for sleep tracking and as an alarm clock every night. The battery lasts for ~2 days, and since the battery is so small it charges really quickly, so topping it off before/after bed for a few minutes is enough so it's always charged.
What app do you use for sleep tracking?

When I work from home I have a standing desk, and it looks like the watch does not pick me as standing, so I almost never reach the standing goal there
How would it actually know if you're standing, especially if you're hands are on a desk? Heart rate, blood pressure?
My reason for this theory is that I sometimes bounce my leg when I'm sitting, and if I have my arm resting on said leg this sometimes triggers the stand goal for the hour.

You've misinterpreted my comment. I didn't claim sensors weren't required. I said that it's a fallacy to claim that the current diagnostic equipment is required. There are sensors on smart watches. Cardiogram is using data from those sensors.
> This kind of procedures are not used because "doctors are old and non-tech people", it's because it's not working.
It's not working yet (at least not enough to make a 100% accurate diagnosis). No one claimed it was. I hate to break it to you, but the equipment currently used in sleep studies isn't 100% accurate either. Neither is the human interpretation made by sleep doctors. However, to say that doctors are laughing it off makes those doctors look stupid, not Cardiogram. Based on the studies they've run so far, it's not hard to envision a future where smart watches and apps will replace a large percentage of doctors whose main source of income is sleep studies.
> Sure, apps and smart devices could replace some day those devices but they need more and accurate sensors. Extrapolation of data from a good-enough pulse rate sensor it's not a replacement.
Your claim seems to be that sleep doctors need input from a large number of sensors, so it can't be possible to make a diagnosis from a single heart rate sensor. It would appear that Cardiogram has presented evidence to the contrary:

If you disagree, make a specific criticism of their evidence.

The apple watch measures heart rate every 5 minutes, and it does do HRV as of watch OS 4.
Fitbit Ionic "Stores heart rate data at 1 second intervals during exercise tracking and at 5 second intervals all other times" - https://www.fitbit.com/shop/ionic#specs I don't know how much useful information you can get from the variability of a metric you only sample every 5 minutes.

This happened to me an hour ago. I stood up at my desk and continued working but it didn't count according to the watch. I'd speculate that it wants some lateral movement as well - stand up and get a drink of water, maybe?
It wants you to repeat the process of standing. So, if you stand for an hour, that is only 1 stand procedure. You have to sit for 5 minutes, then stand again.

Okay. Any way for me to get updates on when it's available for use?
It'll appear directly in the Cardiogram app. (Would you personally find it helpful to have another mechanism, like a mailing list?)

> I now routinely get messages about how I've achieved my standing goal - while lying in bed watching TV or working on my laptop. I routinely get messages about having to stand up while standing up on my standing desk at work. (Series 2 here)
Apple calling it a "standing goal" is a misnomer. Its more of a walking goal. I'm pretty confident that they're actually looking for 1 minute of consistent steps every hour.

Apple has been aggressively branding as the company that does not need to sell your data because their margins on hardware allow them to. It might not always be the case but they can future-proof that claim by keeping that data on your device or protect it using differential privacy. What might happen if health plans become habitually based on tracking (which I expect will be the case) is that having an Apple watch (…
Typical PR spin-doctored hogwash. They don't need it, arguably, but they sure as hell want it, as evidenced by: 1. The extremely lucrative market of personal data 2. Their continued collection of such personal data

This perception of low battery life has really lasted from the first apple watch. It was the reason, along with that it wasn't water proof enough for me, that I didn't get the first one. I wear my apple watch 2 all day, sleep in it, and charge it in the time I'm getting ready in the morning. that's all it needs and it never runs out of battery.
I completely agree; I wore my watch series 3 (no cell) all day yesterday, tracked sleep last night, and this morning I still have 65% battery left. I quick charge while I shower in the morning is all it's needed and I'm blown away by how long it lasts. (I had a Pebble Time previously.)
I'm using AutoSleep, but it seems to really overestimate the time I'm actually asleep, and as far as I can tell it doesn't take into account tossing/turning during the night (either that, or I'm getting way better sleep than I think I'm getting).
