In September 2021, analyst Ming-Chi Kuo predicted that a future Apple Watch will come with a body temperature sensor.
Now, Bloomberg’s Mark Gurman says the feature is probably ready for Apple Watch 8, which will likely launch this fall. According to Gurman, the feature won’t give you a temperature reading, but will warn you if you get a fever. Previously, he also said the feature might be designed to help with fertility planning.
Gurman says the new Watch will likely only offer minor changes apart from the new sensor. The display might get updated on the pricier models (so, not the Apple Watch SE), but the processor is likely to stay the same as on Apple Watch 6 and 7.
The biggest upgrade in the Watch family will probably be the rumored, new rugged model. Gurman says that model will also get the body temperature sensor.
