What data does an app have to write to the health store so that the data is counted to the green exercise ring of the activity app?
Is there a a threshold and how do I figure out that threshold?
So for example active burned calories / second > threshold for at least n seconds would be my guess, but I don't find the information.
Edit
iOS 9.3/watchOS 2.2 adds functionality for the exercise ring but not writing
