Apple’s Ultra watch priced at $799, is the company’s most expensive watch yet. While Ultra works well for diving activities like underwater pool swims or snorkelling, it does not essentially serve the purpose of a dive computer. Its native app ‘Depth’ mainly tells the wearer basic information like water temperature, time, and current and maximum depth.
There is one good news for owners of Ultra – they can now use the watch as a dive computer by pairing it with Apple's Oceanic Plus app that adds seven more metrics to Ultra. Oceanic Plus works as a dive computer that plans, tracks, and reviews up to 40 meters deep dives.
From the surface time, depth, and gas entered by the diver before their dive, the Oceanic Plus app measures a no-decompression time, or the duration estimated for the diver to stay at a given depth. Other information provided by the app includes tides, water temperature, visibility, currents, GPS entry, exit locations, ascent speed, and battery level along with a summary of the dive. In case of reaching the no-decompression limit or ascending too quick, the app also shows color-coded safety warnings.
Although the Oceanic Plus app can be accessed for free, not all its features are free to use. Among the exclusive features are decompression tracking, location planning, and an unlimited logbook, for which a user is required to subscribe to a $9.99 monthly or $79.99 yearly plan. The app could also be used for family sharing in the US that costs $129 a year.
