My Apple watch activity app shows more steps than the iphone health app. The watch is more accurate as I don't always have the phone with me. I'm assuming this is because the phone is only counting steps from the phone accelerometer. How can I make the phone health app sync and count steps from the watch only? This is especially odd as the three ring, move, exercise and stand data are synced and matched between the two devices, why not the step count as well?
