The part that is growing is how many tools rely on apps and other connected features.

I have a blood pressure monitor, and it just outputs the result to a built-in screen. I can then log the values however I want, and it’s probably easier and quicker to manually enter the three numbers each consisting of 2-3 digits into an app than to wait for the bluetooth connection to be established.

This battery monitor will never be remotely shutdown, because there is no remote function. And if the blood pressure tracking app shuts down, I can just use any other.
