There are several existing devices that can do this ! I don’t think this feature is going to be useful to many, I mean adventure sports fans probably already have the above mentioned devices.
I agree this won’t be useful to many. I mentioned this in a previous post. But then i remembered that safety sells. In a car crash, drift away on a paddle board, take a hard fall, get lost in the woods-on a mountain-boat flips over out in the gulf, then couple it with heart and O2, and sleep tracking, other monitoring, the watch alert saved my life.
Essentially this is a “Buy us and you’ll be safe” ad. Apple appears to be trying to take health and safety via iPhone and watch to as high a degree as possible.
