I was wondering if someone could demystify the whole activity tracking component of Apple Watch for me. As best as I can tell data is pushed to the iPhone into the Health app as well as the Activity app. If for whatever reason the watch backup fails to get made transitioning to a new phone and you need to restore the watch and sync it up to a new iPhone, would that data stored in Health.app and Activity.app be pushed back to the watch? Achievements is the most noticable one that would make sense to have pushed back. So wondering if anyone can try to clear this all up for me - thanks!
