Exclusively available on the Apple Watch Ultra, the new Depth app is designed for underwater activities, powered by the new sensor to measure water temperature, depth up to 130 feet, and duration.
The new depth gauge with water temperature sensor, the Depth app on Apple Watch Ultra provides important metrics at a glance like time, water temperature, duration underwater, current depth, and max depth (up to 130 feet) reached.
Here is how to use the Depth app on Apple Watch Ultra during a dive session
The Depth app opens and starts a dive session when the watch is submerged to a depth of 1 meter or more. There are a few ways for users can set to launch the app:
- Set it to launch automatically when the watch is submerged.
- Simply tap Settings app > General > Auto Launch.
- Opening the app manually.
- Customize the Action button to start a dive session.
You can also change the units of measurement in the app like depth in feet or meters and temperature in Fahrenheit or Celsius through Settings app > Depth. To prevent water damage during a dive session, Water Lock is enabled automatically when the Depth app opens.
If you want to record a workout like an open-water swim, begin the workout session through the Workout app before diving in the water.
However, users must keep in mind that the Depth app on Apple Watch Ultra is not a dive computer and does not provide vital data like decompression stop information, gas analysis, or other recreational scuba diving functionality.
Therefore, to prevent fatality or casualty, users are advised to use a secondary depth gauge and timer/watch. Apple’s warning message reads:
Underwater activities are risky. The Depth app isn’t a dive computer and doesn’t provide decompression stop information, gas analysis, or other recreational scuba diving functionality. If you’re using Apple Watch Ultra where the failure of the device could lead to death, personal injury, or severe environmental damage, always use a secondary depth gauge and timer/watch. Before going on a dive, be sure your Apple Watch Ultra is free of cracks or other damage.
