The Oceanic+ app turns the Apple Watch Ultra into a fully functional dive computer. Testers loved the crisp color display, which scored excellent for readability in glaring topside conditions and at depth. The neatly labeled dive display uses bold rounded characters.

Depth and NDL are always in plain sight. Rotating the Digital Crown—a stand-out feature in its own right—quickly cycles through secondary data on the lower half of the display. This lets the computer pack in data, including a digital compass, without ever feeling cluttered or overwhelming. Some testers really liked the altimeter-style ascent/descent graphic, but others found it a little cryptic.

The computer is very intuitive and user-friendly, even for divers who aren’t Apple users. The app can be used for free on gauge mode, but a paid subscription is required to access no-decompression information. Users who are already entrenched in the Apple ecosystem may appreciate the flexibility the subscription model provides—especially new or infrequent divers.

Regardless of how one may feel about Apple products and subscriptions, one thing is clear: The Oceanic+ app offers a simple-to-operate dive computer with a slick-looking display and barely-there ergonomics that made it a favorite among test divers. It is our Testers Choice for recreational dive computers.
