In this week's post, Burns mentions in passing that the Watch will not only learn a user's stride after a few exercises when paired with an iPhone, after a while the Watch will be able to act independently in tracking fitness-related stats without needing to be tethered to an iPhone at all (via MacObserver).
The post, titled "The Art of Vacation Training", finds Burns on a bit of a break from her usual training regimen while on vacation with her family in the Caribbean. Still finding time to put in a 14-mile run in one day, Burns discusses how her personal Apple Watch has since learned her stride and speed, the Watch becoming less reliant on the iPhone in the fitness-tracking departments the more she uses it.
I switched up my runs between the treadmill at the hotel gym and outside. After you run with Apple Watch and your iPhone a few times, the Workout app knows more about your stride. So you can run on a treadmill or outside without your phone and still get a really accurate workout summary.Apple's presentation of the device, ever since its reveal last September, has been of a Watch in nearly constant need of contact with an iPhone. Although Burns' blog post only appears to confirm the Watch's fitness-focused apps can sufficiently work sans iPhone, it's still an interesting piece of information, especially for users planning to use the wearable as a sole workout device.
