At Apple’s presentation in September, it was said several times that the WR100 and EN 13319 international standards were not given to the Watch Ultra by chance, but so that it can be used as a diving computer. The product was released, the hardware was given, but we had to wait for the software, as the Oceanic+ application for diving was only available now, on November 29. The program runs exclusively on the Apple Watch Ultra, watchOS 9.1 is the system requirement, and a paired iPhone 8 or later iPhone running iOS 16.1.
The Oceanic+ relies on the watch’s water temperature and pressure sensors, it also uses a compass, and can signal the diver with a vibration motor and flashing display. The program measures the diving time and depth, indicates if the diver descends or sinks too quickly, displays how long it will take the wearer to return to the surface, and also makes the compass visible if required. The application is also equipped with a planner, which continuously monitors the tides, temperature, visibility and currents in the place specified for the dive, and based on this, gives advice to the diver or warns him not to dive if the situation seems dangerous.

Site-specific planning is not possible with the free part of the program, decompression tracking, location planner and unlimited storage for logging older dives require a subscription, which is $10/month or $80/year currently in an individual package. If you’re diving as a family, the annual subscription is $129 and you can share with up to five people via Apple ID-linked Family Sharing.
