Speaking of the Apple Watch, Apple shipped WatchOS 5.3 today, which allows the ECG function to be used in Canada and Singapore.
Apple’s focus on health capabilities with the Watch is one of their most impressive product directions I can remember from any major company. I know there are cynics who view it as a cash grab on the back of health worries — and, without digressing too much, I think that’s a valid criticism of much of the broader medical industry. But there is also room to interpret this as a genuinely good thing for humanity. It is one of the few Silicon Valley things that can be described as life-changing without hyperbole.
