Apple Watch Ultra 'Depth' and 'Siren' Apps Appear on App Store Ahead of Device's Launch This Friday

Apple has listed two new apps on the App Store that are made exclusively for the Apple Watch Ultra: "Siren" and "Depth."

siren depth apps
Siren is designed for emergency situations if users become lost or injured to draw attention to their location. When the Action button on Apple Watch Ultra is long-pressed, Siren emits a unique 86-decibel sound pattern which can be heard up to 600 feet (180 meters) away.

The Depth app is for use during recreational underwater activities to 130 feet (40 meters), from snorkeling, and free diving, to simply playing in a swimming pool.

Users can see their current depth, water temperature, duration under water as well as the maximum depth they've reached to 130 feet (40 meters). It can automatically activate as soon as Apple Watch Ultra is submerged, or manually launched like any other app.

The two apps are exclusively for Apple Watch Ultra models, which launch on Friday, September 23, so they can't actually be used by the general public yet.

Apple Watch Ultra models will come with the two apps pre-installed, and if users opt to delete the stock apps and then change their minds, they'll be able to re-download both from the App Store.

Priced at $799, the ‌Apple Watch Ultra‌ is available in a single 49mm size, with Trail, Ocean, and Alpine band options available. The new smartwatch can be pre-ordered now and launches alongside the second-generation AirPods Pro this coming Friday.

I don't understand why the watch itself can go to a maximum of 100M but the Depth app stop at 40.

I don't dive so I probably won't use it under 40M, but I find it strange. Is it the sensor who isn't capable to calculate the depth and/or temperature under the 40M?

edit: i answer to myself lol. Seems indeed an hardware issue as apple website claims that the sensor is able to calculate up to 40M so it’s probably the good explaination.
There was a great explanation by an actual Dive Instructor on Waveforms Podcast (MKBHD) where they interviewed 3 experts in diving, running, and hiking. It's worth a listen.



Specifically, the 40 metres relates to where recreational divers can dive using compressed air. Below 40 metres it becomes a technical dive as you have a different composition of gases in the tank and you have a dive computer that will organise a different mixture of those gases depending on the depth. The Apple Watch cannot do that which is why they are saying it needs to be used by recreational divers. (By his estimates), only 5% of people who dive do technical diving, with the rest doing recreational diving.

You can use it below 40 metres and the watch will still function fine, but you cannot use it as your Dive Computer.

Wonder how much they’re going to charge for that Oceanic dive computer app?
As a free app on the App Store, Oceanic+ will include depth tracking (including depth alarms), GPS tracking, logbook (up to 12 dives), snorkeling, and more.

For more advanced diving options such as No Decompression Limit, users will be required to purchase an Oceanic+ subscription plan ($4.99/day, $9.99/month, or $79/year). Oceanic+ will be available on the App Store later this fall.

Well thank you! Seems like a more plausible explanation than the one of the supported depth (no offence Nightfox, it was interesting as well)
