@dang The title should be renamed "Available today, the Oceanic+ app on Apple Watch Ultra" Because the current title of " Apple Introduces Oceanic+" implies this is a 1st party app from Apple, which it is not.

What do you mean? It’s rated to 100m, which is quite a bit below the 40m limit for most recreational diving.
“Rated to 100m” does not mean what you think it means. It means, essentially, that it theoretically would be safe at 100m depth, assuming you lower it slowly and don’t move it about at all . IIUC, local water pressure varies significantly when you move something around underwater, which is why “100m pressure proof” does not mean “can be brought down to 100m depth”.

Movement induced dynamic pressure increase is sometimes the subject
of urban myths and marketing arguments for diver's watches with
high water resistance ratings. When a diver makes a fast swimming
movement of 10m/s (32.8ft/s) (the best competitive swimmers and
finswimmers can not swim nearly that fast) physics dictates that
the diver generates a dynamic pressure of 0.5 bars (50kPa) or the
equivalent of 5 meters of additional water depth.

ISO 6425 is much more stringent and specifies that every single unit is pressure tested to 125% of rated capability, ie a 200M ISO 6425 watch has been individually tested at 250M for a period of time.

It’s not misleading, this is Apple releasing the news and it has obviously been developed in collaboration with Apple. The term “Dive computer” is not something to be taken lightly. It’s hardware you literally depend on to keep you alive during a dive. The fact that Apple is supporting this externally developed app says they have a very higher level of trust in their hardware. Typically a dive computer would cost mor…
Most dive computers cost less (often less than half) than an Apple Watch Ultra and don't require any subscription to maintain functionality. Also, since you are trusting your life to the waterproofing of the watch, a EDC watch that takes abuse all day that could compromise that waterproofing seems like a bit of a risk unless it is only being used as a secondary / backup dive computer.
So it's far more capable than just a dive computer.
And again it doesn't require an ongoing subscription you just turn on/off as you need it.

Why change from one made up title to another when we could just use the _actual_ title: “Reach new depths with the Oceanic+ app and Apple Watch Ultra”
The first problem is battery life. I didn't have to replace the battery on my computer for the 20 dives over a week I did recently. If I had gotten a low battery warning, I could have replaced the coin cell battery in five minutes. With the Apple Watch, I would be uncomfortable starting a dive with less than 80% battery, which means remembering to charge it before every dive. If I forget to charge it, then I cannot quickly replace the battery, and I cannot switch to a backup computer if I hadn't taken it with me on my previous dives as it wouldn't know my tissue loading. Forgetting to charge the watch before any dive would mean missing the dive.
The 40m limit is not a good idea. I imagine Apple's legal department are forcing this one, but it's a really bad idea. I went slightly below 40m a few times last week, I know that breaks "the rules", but I know the risks and they honestly aren't that bad if you don't push things too far. Having my computer lock out, refuse to give me NDL times, depth info or deco stop info if needed is not a good idea, especially when you really need it at those depths.
There is also no mention of nitrox, so I assume it's not supported. That would make this the only dive computer released in the last decade that doesn't support nitrox diving. Nobody who is interested in owning a dive computer will want a computer that doesn't support nitrox.
The one good thing I see about this is the haptics. It's really easy to get alert fatigue underwater from other dive computers beeping around you. Haptics would be far better.

Seems like the proper candidate for HN story title, to avoid the marketing-speak in the actual title.

That is cool. I assume that it has been tested and certified. Dive computers are critical safety gear. You really don't want them crashing on you.
