Doesn’t even work on Apple Watch Ultra 4, just constantly stuck at this pathetic screen asking me to login from my phone by pressing the sync button in settings. Said sync button literally does nothing except instantaneously say “can’t connect” as if it didn’t even attempt, there is absolutely no way to just do it from the more than capable watch. Just a complete joke how sad technology is allowed to be in 2026.

Easy to use and practical.

Has been easy to use, great detailed information and interface with my phone….

I tried many times, it just can not sync with my Apple Watch Ultra 2

I have had their annual plan for two years with no issue and their monthly plan last year. Two weeks ago, I signed up for their daily plan and they charged me twice and refused to refund. Buyer beware.

The Oceanic app on the Apple Ultra and the iPhone have performed well on my last couple-hundred dives. I bought the Ultra and app in November 2022. We got acquainted. Then the April update erased my logbook off the Ultra. Good thing the logbook remained on the iPhone. Then the Ultra took DAYS to sync with the iPhone. That delay has been fixed. I LOVE the safety stop countdown. The Ultra logbook has now been reliably syncing with my iPhone. I also like the depth and temperature graphs. The Ultra is easy to read underwater. If you are a diver who is already in the Apple Watch ecosystem, then I highly recommend Ultra and Ultra 2 and the Oceanic+ app. I updated to AWU2 in late summer 2023. Very happy.

I use a Shearwater Teric with air integration as my primary computer. The cost for the 30 day subscription is a great deal for a backup dive computer. The display quality of the Apple Watch Ultra is perfect underwater. I love how it tracks GPS in and out set points. The logbook is much nicer than shearwater. If the Apple Watch ever pulls off air integration, it might be worth considering switching full time. I would however prefer to sync my logs with subsurface app, so I can combine all my previous dives.

App as is works great! Would love it if you could add a map access function when installed in the casing so we could see our location while at depth.

Between Apple and Huish Outdoors, this app effectively forms a closed monopoly on the Apple Watch Ultra, forcing divers into an aggressive and expensive subscription model with zero real competition. To make matters worse, you can't even rely on it when you're on the boat: the heavily advertised auto-launch feature is completely hit-or-miss. Standing at the surface waiting for a critical safety app to trigger shouldn't feel like a gamble. For a setup this expensive, it's unacceptable that basic reliability is secondary to a paywall.

First dive using App. Loved it. I say face to read. Loved having vibration reminders. I’m done using my console. I’ll keep it as backup. Profile data compared perfectly with my Shearwater computer.
