The Apple Watch Ultra 4 introduces a new health-sensing system that enables more accurate, continuous heart rate monitoring every five seconds. The device features a slightly heavier titanium case, weighing 63 grams for the natural titanium model and 63.1 grams for the black titanium version. Internally, the watch is powered by the new S11 dual-core processor, paired with 64GB of storage and the second-generation Ultra Wideband chip. Battery performance has been improved to 50 hours, up from 42 hours in the previous generation, while maintaining the same 45-minute charge time to 80% capacity. The watch supports Wi-Fi 4, Bluetooth 5.3, and 5G connectivity. New software features include audio intelligence, which allows for sound and name recognition, and the Readiness app, which provides a daily score based on activity, vitals, and sleep data. The device also includes new gesture controls, such as double-tap, for navigating the interface with one hand.

Worth noting
- The Readiness app requires up to a week of data collection to activate, and the presenter notes that they do not typically wear the watch to bed, which may affect the accuracy of the data.
