Fall detection and EKG.
Despite being an Apple geek, I had no interest in the Watch, mostly because I have a lot of joint pain, and wearing something on my wrist wasn’t appealing. But I have MS and other health issues, and live alone, so I was already aware that I needed a way to reach help if I had another bad fall. The series 4 came out with the right features at the right time.
Beyond the peace of mind I feel wearing it, I’m also enjoying it a lot overall. Two things I didn’t expect to love as much as I do are Apple Pay on the watch (who knew it’d be so much more convenient than the already super convenient Apple Pay on the iPhone?) and being able to adjust volume and other controls for podcasts and music playback without taking the phone out of my pocket.
