But for degrees Celsius or Fahrenheit, you'll have to get, like, a thermometer.
From Gurman’s Power On column, posted Sunday to registered Bloomberg Technology subscribers:
In April, I reported that Apple has been aiming to add body-temperature detection to its Series 8 model, assuming the capability passes muster during internal testing. I now believe the feature is a go for both the standard Apple Watch Series 8 and a new rugged edition that’s aimed at extreme sports athletes. It’s unlikely to be available in the new version of the lower-end SE, which is also coming this year.
The body-temperature feature won’t give you a specific reading—like with a forehead or wrist thermometer—but it should be able to tell if it believes you have a fever. It could then recommend talking to your doctor or using a dedicated thermometer.
Other than the body-temperature reader, other hardware changes will probably be minor.
My take: If true, seems like a missed opportunity. What this consumer wants are digits he can read without his glasses.
