My partner and I are getting older, and sleep in different rooms at different times. We’ve both worried about the other dying unbeknownst. I wear a pulse watch, but don’t know if it will do what I want. Any ideas, friends? I’d like us to be able to glance at a screen and see a heartbeat, ideally without spending more than a couple hundred dollars, and without too much hassle or cumbersome equipment. I appreciate any suggestions. (edit - we use android and Linux.)
I remember seeing this ring built specifically for this purpose. It was an unobtrusive metal band and you could synch it up to its pair and it would squeeze your finger in time with the pair’s heartbeat sensor, I’ll see if I can find it again
