I wonder how this'll work. If you're walking with both, will it know that they're both happening at the same time? You're going to have the watch on you all the time, and the phone you leave on your desk a lot, so the watch will have a higher count than the phone. Will the phone know the difference? Or sometimes, much less frequently, you may walk with your phone without your watch on, what happens to the discrepancy? Will the steps even be aggregated or will they be separate? Such that you can only see your steps with the watch on the watch, and only see your phone steps on the phone. Nothing we've seen, as far as I remember, suggested that the watch's step counter will be integrated with the phone's. But it'd be silly not to. Does the pedometer on the phone even matter now that it's on the watch? I wondered if maybe the combination of having a phone in your pocket and also wearing the watch would give an even better reading of your activity, by interpolating your legs and arm movements. Thoughts?
