I would like to buy an AW and pair it to my wife's iPhone (I own an Android phone). How can I prevent the AW from updating Health data on my wife's iPhone? She likes to tracks the steps she does everyday I do not want my own data to interfere with her own data. I know I would loose a lot of functionalities by not owning an iPhone but I need a new watch and I might as well get an AW than a dumb watch. I really like the simplistic design of the AW.
