It looks like the Apple Watch will be able to track workouts without the need for an iPhone, which means that you wont need to take your iPhone with you when you go for a run.
The news comes in the form a blog post by Apple Watch spokesperson Christy Turlington-Burns, who posted a new blog on Apple’s website.
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.
So it looks like you wont need to take your iPhone with you when you go for a run if you just want to use your Apple Watch to track fitness.
The Apple Watch launches on the 24th of April and Apple will start taking pre-orders on their new smartwatch on the 10th of April.
