Apple Watch Ultra 4 Review: The smartwatch for the health-conscious

This article is a review of the Apple Watch Ultra 4, a smartwatch designed for health-conscious individuals. Unveiled last week, it will launch properly tomorrow, but some of its features won't be available until later this year, depending on the region. Apple provided a review unit of the Ultra 4, and the author focused on its capabilities.

The watch boasts a longer battery life and a new heart rate monitoring system, which Apple claims is the best in the industry. The case is made of titanium in natural or black colors, and has a 49mm size. The display resolution is 422x514 pixels with a wide-angle OLED and LTPO3 display. The chip used is S11 with a 4-core Neural Engine, and it has W3 wireless chip, 64GB storage, and supports various connectivity options including GPS, cellular, Wi-Fi4, Bluetooth 5.3, satellite connectivity, and second-gen Ultra Wideband chip.

It offers up to 50 hours of normal use battery life, 84 hours in Low Power Mode, and 18 hours in outdoor workout mode. Its durability is rated at 100m water resistance and dust resistance IP6X.

The most significant hardware change includes a new Health Sensing System with a new optical and electrical heart sensor, allowing for frequent heart rate measurements throughout the day. This system aids in calculating stress indicators, such as HRV (Heart Rate Variability). A new feature, Readiness, uses a week's worth of data to assess readiness for workouts. The watch also offers more precise health-related apps, like Vitals and Heart Rate.

Overall, the Apple Watch Ultra 4 seems to be a reliable and powerful smartwatch for athletes and adventurers, with improved battery life and a new heart rate monitoring system.
