How To Set Up Siri Shortcuts
To set up a Siri shortcut, go to the Account tab, then tap on Integrations under the Settings section and tap 'Add Shortcut to Siri'.
Siri Shortcuts works on both Apple Watch and iPhone, and you can ask Siri to start, Pause, Resume, or End your recording. If you're having trouble getting it to work or you're finding that the Fitness app is popping up instead, try being more specific with your command by mentioning Slopes, for example, 'Start skiing with Slopes'.
Just keep in mind that as it stands you currently have to unlock your phone to use Siri, you can read more about that here.
