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

Cool. I wonder why siren cannot be included in the regular one though

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.

They don’t come pre installed?

I guess they do put are removable so would need them to on the AppStore to be able to reinstall them

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.

Water resistance ratings on watches are very misleading - they generally relate to a static pressure (i.e. if the watch is stationary, in stationary water) but this is not representative of 'real' pressure that would be experienced at that depth where undersea currents or just moving your arm could significantly increase that pressure.

This table shows the very big difference between the static pressure rating (middle column) and what that actually equates to (right column). Even 3 ATM/30 meters isn't rated for simple surface swimming. So, a watch rated for 10ATM/100m isn't actually suited to use at depths of 100m.

“…Siren emits a unique 86-decibel sound pattern…”
My mom needs this sound as her ringtone so she doesn’t miss calls.

Water Rating	Definition	Suitable
IPX7	Withstands incidental exposure to water of up to 1 metre for up to 30 minutes	splashes, rain or snow, showering
IPX6	Protected against powerful jets of water. Water projected at all angles through a 12.5 mm nozzle at a flow rate of 100 litres/min at a pressure of 100 kN/m2 for 3 minutes from a distance of 3 metres	heavy spray, driving rain, boat washing, outdoor use in rough sea conditions
1 ATM	Withstands pressures equivalent to a depth of 10 metres	splashes, rain or snow, showering
3 ATM	Withstands pressures equivalent to a depth of 30 metres	splashes, rain or snow, showering, jumping into water
5 ATM, Swim	Withstands pressures equivalent to a depth of 50 metres	splashes, rain or snow, showering, swimming, diving into water, snorkeling
10 ATM	Withstands pressures equivalent to a depth of 100 metres	splashes, rain or snow, showering, swimming, diving into water, snorkeling, high-speed water sports
Dive (up to 11 ATM)	Tested to engineering standard EN13319 for dive compliance	splashes, rain or snow, showering, swimming, diving into water, snorkeling, high-speed water sports, scuba diving

well yes but according to apple website, the ultra is responding to the standard EN13319 This correspond to the 11ATM according to what you sended so..

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.

The Ultra got a different speaker. On the regular watch it'd only be a feeble beep.

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