5 hours ago my Apple Watch stopped logging my steps, walking distance, heart rate, etc. What would the reason be for this? I only noticed right now when I checked my Health app. I'm on iPhone 5 so it's nothing to do with my iPhone not logging this. 3 hours ago I went to the gym and it was showing the calories burned and my heart rate. I used it to skip music that was on my iPhone, my activity bars are filled, so I can't work out what the problem is.
