Is there a way to have steps recorded by the iPhone contribute to active calories in Apple Health? For example, you wear an old school watch when walking to the shops and then later put on the Apple Watch when going to the gym.
With a Fitbit tracker there is the ‘mobileTrack’ feature which you means you can walk around without your Fitbit tracker and the phone steps will help calculate total calories on the Fitbit database. In practice this means you can wear a nice regular watch when walking around the shops etc or catch up with friends and then when you exercise properly you put on the Fitbit tracker and the software will reconcile the two sources of information.
I experimented with a random pedometer app in the app store that contributed active calories to Apple Health when walking but I found the Apple Health was doubling up on the active calories from the watch and from the pedometer app.
For me this is by far the biggest negative anti-feature of the Apple Watch.
