The Oceanic+ app will be available on the Apple Watch. The app is designed to be used for recreational scuba diving at depths up to 40 meters/130 feet.

The Depth app on the Apple Watch allows you to see your current depth, maximum depth reached, water temperature, and duration under water. The app will be useful for scuba divers who want more advanced data.

It shows a diver's current depth, dive time, no-decompression time, water temperature, time to surface, maximum depth, and much more. No-decompression limit, excessive ascent rates, and safety stop guidance are provided by the app. A summary of the user's dive profile is displayed on the watch after a dive.

The app will be available on the App Store, but only if you have an Apple Watch with watchOS 9.1 or later. The basic plan is free and includes a log of most recent dives. Users can get access to a number of features for a fee, such as tissue loading, unlimited logbook capacity, and more.

More detailed post-dive summaries, tides up to three days in advance of a dive, and more can be found in a companion app for the iPhone.
