Are there any new health features introduced with the S9 chip in the Apple Watch Ultra 2

New Health Features with the S9 Chip

1. Enhanced On-Device Siri:
- The S9 chip allows Siri to process health queries directly on the device, improving speed and privacy. Users can ask about their sleep patterns, heart rate, and log health data such as weight and medication intake without needing an internet connection[2][4][8].

2. Double Tap Gesture:
- This new gesture enables users to interact with the watch using one hand by tapping their thumb and index finger together. It facilitates hands-free control for various functions like answering calls, snoozing alarms, and controlling playback playback, which is particularly beneficial for users with disabilities[3][4][8].

3. Sleep Apnea Detection:
- The Ultra 2 includes a new FDA-approved feature for sleep apnea detection, which monitors breathing disturbances during sleep. This feature provides insights into potential sleep apnea issues by analyzing nightly breathing patterns over time[3][4].

4. Vitals App:
- A new Vitals app tracks multiple health metrics including heart rate, respiratory rate, and wrist temperature during sleep. It alerts users if their readings deviate significantly from their established baseline[3][4].

5. Comprehensive Health Monitoring:
- The watch retains existing features such as blood oxygen monitoring, ECG capabilities, and high/low heart rate notifications. These sensors work in conjunction with the new software capabilities to provide a holistic view of the user's health[1][5].

Overall, the S9 chip significantly enhances the Apple Watch Ultra 2's ability to monitor and manage health data effectively, making it a powerful tool for fitness enthusiasts and those concerned about their health.
