Compare the Apple Watch Series 8 to the Apple Watch Series 7

The Apple Watch Series 8 has a new and extra accurate temperature sensor. This sensor also constantly tracks your temperature at night. This way, your Apple Watch can identify possible deviations in your menstrual cycle. A deviating cycle can indicate that you're ill or that you will be. The Apple Watch also calculates when your fertile windows was. That's useful if you want to start or expand your family. The accident detection is another addition. If you're in a car accident, the Watch automatically sends a notification to emergency services and your emergency contacts.

The Series 7 doesn't have the new temperature sensor. You can track your menstruation, but you need to enter the data yourself. The notifications for a deviating cycle and predictions of your fertile window are less accurate than with the Series 8. The Apple Watch Series 7 doesn't have accident detection, only regular fall detection. Your Watch does send out an emergency message when you fall, but not when you're in a car accident.
