Speaking of heart rate, yes,I can’t believe I may buy an Apple watch. The news ones do monitor your heart ... AND do an electrocardiogram and automatically email it to cardiologist or doc. Not bad, as I am 70 in 3 days.
Also, It tracks your mobility “tripping”, “falling” or “slipping” ... it gauges whether you get up in a timely fashion and calls Emergency Services if you do not respond ...also calls your emergency contact.
I was stunned when I got to be elderly to find that I fall often... or more often than I would like. Some have been close calls and could have been on stairs given one of my places had lots of stairs.
Turns out that Apple is not just the biggest phone/watch sold ... it completely took over the plain old watch market outselling every other make.
Not a surprise really, as anyone watching the cell phone market made the observation that when someone wanted to know the time, they would look at their cellphone, not their watch.
Watches are pretty much dinosaurs without ones with computers and many of the super high-end brands have had Apple do a version.
Yes I think the sacrifice in privacy is worth the Apple Watch features, particularly for people when they get to be that age where things start going a little sideways health wise.
