No body temp sensor!

[ApfelKuchen]

I expect the OP is just going to have to wait for the AW of his dreams.

Here's the thing about waiting for ones dreams (the all or nothing at all proposition) - you lose out on whatever is currently available. If you know the wait is relatively brief, then the wait may be worthwhile (I want an iMac with Apple Silicon - I have good reason to expect that dream will come true within a year). On the other hand, as much as I'd like my next car to be self-driving, the lease on my current vehicle is up later this year. Will I go without a car because I wish the next one would chauffeur me around? No.

If the only thing one wants from a watch is a body temperature reading, then there are other tools available. Watch is already useful to me for a wide range of other reasons. Body temperature (when integrated with health warnings) seems like a useful addition, but I can't imagine it being a make-or-break requirement.

This seems more likely to be an excuse for not doing something one doesn't want to do in the first place. I'm quite confident that if the current capabilities of Apple Watch are not already compelling, body temperature will not be the feature that tips the balance (for a significant number of people). For most people it will be an, "Oh, that's nice" feature.

I suspect that if/when AW does have a body temperature sensor, the OP will have another reason for not buying.

I use a Kinsa oral digital thermometer with its app. Take temp twice a day most days. Highly accurate blue tooth links automatically to its app.

Dude...

The thing is your body core temperature is very constant at usually 36.5-37.5°C (97.7-99.5°F). Especially your head, but also your torso keep this temperature. This is why you measure body temperature rectal or under your armpit. Less invasive (i.e. in public, airports etc.) is a measurement at your forehead, but already less acurate.

If your body is getting cold, bloodflow in your arms and legs, especially on the skin is reduced, which cools down your skin temperature on legs, arms, wrists, feet, possibly by a couple degrees. There is no linear relationship between wrist temperature and body core temperature.

Therefore, such a measurement does not indicate anything. It has no health or medical indication to measure your wrist temperature. This is why Apple does not provide it. They could include a sensor on the front, so that you'd have to hold the watch on your forehead or under your armpit.

This company has implemented a body temp using your finger...interested how this may be integrated into the WATCH.

No, they sort of haven't; but still have, to the point of confusing people.

Basically they make assumptions about your sleeping environment being somewhat stable, and then assume that the measured changes are sort of relatable to changes within the user (and not just the user moving, wind changing the temp in the room, and so on).

What that practically means is that you get a lot of data that's close to useless by itself, but when you look at a graph over longterm data you get something that indicates something.

That's not useless in itself, but let's just say that it has very little to do with actual core body temperature as the average consumer assumes. And that makes it tricky for Apple to implement right.

From their FAQ
“Oura registers your body temperature reading every minute while you sleep. The Oura app doesn’t show absolute temperature values in Fahrenheit or Celsius, instead it shows how your body temperature changes around your own personal baseline over days, weeks and months.”

So it’s useless. They won’t even tell you the temperature value because it’s probably not even close to your core body temperature.
