I recently upgraded my Series 6 to the Ultra 2 and the on-device Siri is life changing for someone who utilizes the watch every day.
Currently, the feature is limited to basic tasks like
- Starting or ending a workout
- Starting custom Shortcuts
- Asking your current step count
- Asking to do a toss coin
I never use Siri on the iPhone, I think for wearables it is different. I can do now some tasks that require too much screen interaction down to few to none.
Now, I can start and end a workout without stopping from an activity. It could be a little improvement, but it is remarkable. For context, I never bring my phone during any of my workouts, so the new feature is fitting for my usage.
