I have 2 iPhones: work and personal. For IT dept. reasons, I have to use a different Apple ID on each device: a work Apple ID and a personal Apple ID.
I track my steps in Apple Health on my personal iPhone, under my personal Apple ID.
Sometimes I carry both devices, sometimes I carry only one. Is there a way to set it up so that whichever device I'm carrying (work, personal or both) all my steps will be collected (and de-duplicated) under my personal Apple ID? (So I miss tracking as few as possible.)
I suspect there might be a way to do this by collecting data to a third party app that I have on both devices, but which only writes to Apple Health on the personal device.
