project with Stanford on this. My take from what Cook said is that people with the watch will be able to work with Stanford and will be able to sign up in the coming months. He did mention that the FDA is interested in working with them on this and that they have been very good to work with.
I know that a lot of people use the monitor that you attach to the back of your phone and then hold with both thumbs. My mother-in-law uses it but struggles at time. If she could use the watch for this reason it would be great.
