Does it automatically track all activity?
Will it know i am walking and track it and then know i am running and track that and know i am sleeping and track that ect. Or do i have to physically select the activities i will be doing first?
No it will not automatically track your workouts or sleep. Your steps on the other hand will always be tracked. But if you want to track walking or running or your sleep, you just simply select it (it takes less than 10 seconds to do it).
