The most recent thread on this seems to be from 2019, so I thought I'd ask the question anew. I've never had a smartwatch. I live alone and am in good health in my 60s, but thought it might be prudent now that I'm retired and don't have to show up anywhere every day. That is, if I fall and can't move, I could at least if not unconscious make a call to 911 from the smartwatch--that kind of thing. But if I'm going to invest in one, I wonder which will provide me with the most bang for the buck. Fitness/activity tracker? Blood pressure/oxygen or other health measurements? What else should I look for? Just want this group's recommendations before I start wading into all the information and hype out there! Thanks.
