Apple Watch Series 3 ski tracking Apple Watch Series 3 was announced to have ski tracking possibility. But I cannot find any information on the web if it already possible. Can anyone that has Apple Watch confirm, that you can now track skiing activity, and if so, what exactly can you track? Does it offer similar capabilities as Slopes or Trace apps?
There's still no ski tracking capabilities in any of the Apple Watch series. 

But, all the data inputs needed are there. Barometer, motion tracking, heart rate tracking, location via GPS and cell tower trilateration, etc...

After the initial announcement, Apple referenced that this feature would be available toward the end of 2017, probably before winter.  

The HomePod IPSW leak a few months ago provided some indication that Apple would add this feature to Workouts.  This screen grab shows there's references to skiing workouts already built into the firmware.


For now, you can use the myriad of different ski tracking apps out there.
