We take this approach with our biowatch, but it's a different demographic that also charges a smartphone every night. With seniors, I worry that it comes off to charge it may not go back on. And the loss of faculties related falls starts to correlate with loss of memory and further dementia.

That said, they are honing in on the user experience at nursing homes. Independent living facilities offer a slightly different demographic and likely closer to their goal. Worst case, the device is sending low battery pings, and that itself is an opportunity for children to check in.
