1 Apple ID - 2 iPhones - 2 Apple watches
Wife and me share 1 Apple ID on all our apple devices, I understand the Family Sharing option but find it a pointless cost as there are only 2 of us (happily together for over 35 years) and as such, each of us have access to iCloud, music etc etc. anyway.
My question is - Having recently bought my wife an Apple Watch (I've had one for several years) is there a way to use the same Apple ID for both watches/iphones without the watches trying to share activity data?
