I would hope that interfaces to Apple health, etc. that work through Bluetooth will continue to work, but they still require the mobile app to facilitate it, and as far as google is concerned it’s now living on borrowed time. Two years from now and it’ll be in the graveyard along with everything else.
What do you do about that except give in and let Google acquire even more aspects of your life to resell it, or abandon the tech and produce more waste?
