The Watch Series 8 has two temperature sensors with an accuracy of up to 0.1° Celsius. By continuously measuring the temperature of your wrist, combined with your heart rate, the Watch S8 can predict the course of your menstrual cycle. In addition, users receive a notification when it sees any abnormalities.
Apple hopes to address privacy concerns by only storing data on the watch itself. Stored data is encrypted. Backups in iCloud have end-to-end encryption enabled, and Apple claims it does not have the key.
Car Crash Detection
In addition to the "cycle tracking" feature, the Watch Series 8 also gets a sensor that can detect whether you've been in a car crash. Of course, both Apple and we hope you never have to use this feature. If the watch thinks you've been in a car accident, it can call emergency services and give your location.
Apple has released new watch faces, and a new Low Power mode will turn off power-hungry features like the Always On display and Auto Workout detection. Turning off these features should boost battery life to a whopping 36 hours. Turned off, you'll get 18 hours on a single charge.
