Two health and safety features headlined the launch. First, the temperature sensor with a two-sensor design (one nearest the skin, another under the display to reduce environmental bias): it samples wrist temperature every five seconds during sleep, detecting changes as small as 0.1 °C, and enables retrospective ovulation estimates within Cycle Tracking. Second, Crash Detection: a sensor-fusion algorithm using the highest dynamic range accelerometer in any smartwatch, a new gyroscope, the barometer, GPS and the microphone, trained on data from simulated real-world crashes. It also added international roaming and watchOS 9 Low Power Mode, stretching battery life to 36 hours by disabling the Always-On display and other features. Aluminum in starlight, midnight, silver and (PRODUCT)RED; stainless steel in silver, graphite and gold. From $399 in the US. (Apple newsroom, Apple Support, EveryMac.)
