As part of merging into a SPAC, Rockley announced Apple as its largest customer (https://www.telegraph.co.uk/technology/2021/05/01/apple-watc...).
That PDF covers what they can monitor, including glucose indication, continuous glucose, BP, and other biomarkers. Slides 25-28 are mostly about their product roadmap and unnamed existing alpha customers.

...I'd stay the hell away if I were you.
For example, I've heard that some people have spikes after eating bananas, but other people do not. Also, rice can be very bad for some people (and different kinds of rice have different effects). I'd be curious to wear one for a month or so just to see how my body reacts to various foods and combinations of foods. I think it's possible to rent devices that do this, but it's hundreds of dollars for not that long of a trial. If I could spend $400, gather data for a month, and then sell the device in like-new condition for $250, that'd be a win in my book.
For example, if I could make my liver 20% healthier by eating more moderate portions of bread in a meal where I plan to eat dessert, it would be useful to know that.
On the other hand, I don't think I have to wear the device forever to gain this information. I could learn about what makes my blood glucose spike after a month or two, and then just carry that knowledge with me going forward.
I mean, the potential health benefits in terms of preventive care seem to be incredibly large to me.
It made some sense to me, but ultimately considered it would work out for the greater good.
So I feel like your doctors maybe don't understand or appreciate technology.
My argument is that those machines are highly accurate, or at least the most accurate in order to diagnose.
This extends to the other measurements too like respiratory rate and bloody oxygen saturation.
What they usually do is find a small company with some compelling technology and then either fund it to gain exclusive or privileged access, or buy it outright. The story here (that a small company working on cutting edge sensors has close links with Apple) fits that pattern perfectly.
Sure, maybe apple is first this time but I have a hard time believing Apple is at the cutting edge of new medical technology.
I don’t know about how innovative these rumored sensors may to comparatively, though.
Not the sensor itself, mind you. That's been approved forever, just the ability to read it with an app instead of their dedicated NFC reader.
I’ve never heard of a manufacturer being successfully sued over this. If it was going to happen, it probably would have happened by now. The law has never had much sympathy for drunks.
Even having crude data will let me know how fast various formats of alcohol are uptaked and processed out so if I have a drink with friends, I would know ahead of time if I should take transit vs walk in park after and then drive or stick to alcohol-free drinks (most people I know are cross town in a way public transportation is not cheap/quick but a car is).
Edit: I do use a breathalyzer on myself now, but they are annoying to take samples, and are not super accurate either
But I foresee lots of lawsuits making Apple shy to offer it. No matter how smart Apple is at making it legal, there are always amateurish or vindictive governments that will make laws that cause Apple to risk responsibility.
And the killing of buzz is bi-directional too!
It somehow can see microscopic features in moving blood through the skin and blood vessel walls?
Rockley Photonics has developed non-invasive optical sensors for detecting multiple blood-related health metrics, including blood pressure, blood glucose, and blood alcohol levels, many of which are only normally detectable with more invasive dedicated medical equipment. Rockley's sensors beam infrared light through a user's skin, much like the existing sensors on the back of the Apple Watch for detecting heart rate and blood oxygen levels.
Blood pressure, on the other hand, is very difficult to measure, and it fluctuates wildly based on a wide variety of confounding factors. It would be amazing if they figured out a way to get this information optically.
That page also claims there isn’t any clinically or commercially viable product yet. That seems out of date to me, given that https://www.labiotech.eu/best-biotech/needle-free-glucose-mo... mentions 8 devices you can buy now.
"needle free" !- "non-invasive".
Several of those devices are implanted subdermally.
And now I can’t stop thinking about wearing a Raman spectrometer on my wrist :)
Not sure how close it is to being out of the lab but it definitely seems doable.
If you have a wearable spectrometer (i.e. measure the wavelengths that are reflected), and a variable light source (i.e. control the frequencies sent into the body), you can isolate repeating patterns, even for molecules like glucose: https://youtu.be/xMa1BQ8z9C0?t=541
I'm still not sure how they can tell the parts per million, etc. Probably through multiple samples over time, or multiple veins.

And could such hacking lead to injuries or deaths?
I'm a little skeptical that it's possible to get accurate absolute measurements of those things purely optically, through skin and hair and while the body is in motion, across all skin types, ages, etc. That would be pretty magical.
I can't speak to the quality of the following series, but if that isn't good enough, what is?
