The Apple Watch 8 feature I was most excited about might not work at launch


Apple is expected to announce the next device in its Apple Watch lineup in September, but its rumored body temperature sensor might not work at launch.

The Apple Watch 8 has long been believed to include a way to monitor the wearer’s skin temperature. This tool would provide numerous benefits including being able to better track sleep cycles, possibly indicate if you have a fever, and even detect if you’re ovulating.
