Here are some of the new features of the Apple Watch Series 8:

• Temperature sensor: This sensor can track your body temperature while you sleep, so you can see changes over time. Cycle Tracking uses this data to provide a retrospective estimate of when you likely ovulated, which can be helpful for family planning.
• Crash Detection: This feature can detect if you have been involved in a serious accident and automatically call emergency services.
• Sleep stages: This feature tracks your sleep stages (light, deep, and REM) so you can better understand your sleep patterns.
• Enhanced Workout app: This app has been updated with new workout types and metrics, making it easier to track your progress.
