So the primary use is limited to around half of the population at launch and potentially new headlining usage later?

From an upgrade perspective, it’s probably wiser to go with a series 7 if once doesn’t have it than an 8 at this point? What else does the Series 8 offer?
Check out the Oura ring. It has a temperature sensor and is useful for everyone. It does not tell you what your body temperature is, what it does is take a baseline of your body temperature. Then everyday it tells you the deviation + or - of where you are from your baseline. Usually a person is a few decimals from there baseline (normal), but when you are whole numbers off your baseline (gonna be sick) you know something bad is coming. It has been fantastic for detecting if you are about to be sick or get Covid. Hopefully the Apple Watch will do this too.

This isn't new tech folks. Garmin, Fitbit, Whoop, and others have had it for years. You can NOT determine internal body temp from skin temp, there are too many variables... temp of the room, temp when you are outdoors etc. which all affects the temp of your skin...

Words matter, and "can NOT determine" is not correct. You CAN measure body temp from skin.... you CANNOT guarantee its accuracy.

The CORE Body Temperature Sensor is now widely used by many professional athletes and pro cycling teams as a non-invasive way of measuring core body temperature using just skin temperature, heart rate and a few fancy algorithms. It may not be as accurate as rectal measurement (which isn't always practical in the middle of a sports event!) or a sensor /transmitter that you swallow (which gets expensive and can also vary as it travels through different parts of your digestive system), but it's seen as good enough to provide meaningful and useful heat-training data.
 
This is bad news for this poor company, Apple has a history of sherlocking companies' features and tech, then leaving them high and dry. I'm willing to bet that Rockley will be bankrupt soon.
Such a shame.
Yup. That was my thought as well. Good luck to those folks, either way. I hope for the best for them.

Apple Watch kinda sorta does this now with HRV measurements (and recorded/viewable in the Health app). You can use HRV as an indicator for what you said, but you gotta watch it, tho, and it's not something prominently displayed anywhere. You can add it as a "favorite" measurement in Health, but you still gotta look at it intentionally; no alerting available.
Yeah I know... "uggh soooo much work to remember to tap an app and scroll a bit..." 😂
 
I am a super fan of using temperature for fertility tracking and prevention. No hormones added!

Also, as a male, I would love to see how my temps change over time to see if that correlates to some male hormone cycles (if there are) or other changes in my day to day mood or energy levels. Excited to see what they add!

Yeah but you also need to have your cell phone coverage through them.
Are there any providers who allow a line for watches without a phone line? CmdrLaForge mentioned 'value' carrier (and value may be subjective) but Visible is $30/m, which is rather affordable stateside. Other MVNOs I think of like Mint mobile and Google Fi don't even support cellular lines for watches.
 
The thermometers in the store you hold up to your forehead. Why not just build a sensor like then behind the screen and then touch the face of your watch to your forehead until you get an alert that its done. Sounds weird but its no weirder than touching your finger to the crown to get an EKG.
