As someone with a chronic and severe heart condition, this stuff has the potential to be life-changing/saving. I hope it works well in practice. I know even just being able to track/record/graph my heart rate all day every day has been a benefit to me while using my original series Apple Watch.
it's great to read these. I was expecting some cynical hot takes downplaying the significance of these features. Like, the fall detection is AMAZING for elderly folk.
Series 4 is an insta order for me.
