Apple Watch Ultra becomes a diving computer with launch of Oceanic+

The Watch Ultra has depth gauge and water temperature sensors that drive some of the features in the app. In September, Apple announced a new wearable called the Apple Watch Ultra, and one of the company's key pitches for the device was its use as a diving computer. The app—which was developed in partnership with Apple by a company called Huish Outdoors, lets you track dive conditions like tides, water temperature, and more.
