Never owned an AW but considering one. Looking at AW SE. The Apple Watch is designed with a strong emphasis on fitness and health features - in which I’m not interested at all. I would use AW for notifications and communication and that sort of stuff. Is it possible (and how easy?) to disable all fitness and health related stuff, deny sensors to measure me, remove related apps, etc? Or is that stuff too heavily integrated in AW?
its quite easy to do
using the Watch app on iPhone:
go to Privacy tab.
There you can turn off a lot (most?) Health and Fitness tracking. All of the following:
Heart Rate
Blood Oxygen (if you have a model that has that feature)
Wrist Temperature (if you have a model that has that feature)
Respiratory Rate
Time in Daylight
Environmental Sound Measurements
Headphone Audio Measurements
Fitness Tracking
In same app, go to Sleep section and
click "Dont use this Watch for Sleep"
there might be more, but the above are a good start.
