What can I do with Apple Watch 9?

With an Apple Watch Series 9, here are some key things you can do:

Health & Wellbeing

• Monitor heart rate and receive alerts for high and low heart rates, irregular rhythms, and fall detection.
• Take electrocardiograms (ECG) using the third-generation optical heart sensor. Note that the ECG function isn't available in new Series 9 units sold in the United States.
• Track daily exercise sessions, calories burned, and sleep stages.
• Temperature sensing, although not medically accurate and primarily designed to enhance the cycle and fertility tracking of women's health options.
• Receive more personalized insights from the ECG and heart-rate data, thanks to watchOS 10.

Interaction

• Perform quick actions with "Double Tap," which adds the capability to interact with single-hand gesturing by tapping your thumb and index finger lightly together.
• Respond to messages and provide voice input locally with improved on-device processing using enhanced Siri capabilities.

Convenience

• Brighter display with enhanced visibility in various environments.
• Locate a misplaced iPhone using Precision Finding with distance and direction cues.
• Run the updated watchOS 10 operating system featuring enhancements like new apps, Smart Stack, and faster rollout performance.

Communication & Notification Management

• Send messages, make phone calls directly from the watch, and manage notifications more efficiently due to processing speed improvements and watchOS updates.

Note that while these functionalities might vary depending upon location and related regional configurations or carrier services.
