Apple claims to be the first to add EKG to a smart watch:
They're not really first, but it's still cool. I'm in favor of pretty much any biometric monitoring that's not invasive, and I can definitely see the use of an EKG.
While adding another type of sensor gives me more data about myself, what I'm really interested in is finding ways to get value out of the data I'm already collecting!
I love my wearable when I'm exercising. But to be honest, I'm doing very little with the data. I view my heart rate myself while running, occasionally review it later, and once in a while I'll show it to friends because I think it's cool (though I don't think they care much about my heart rate).
What we need are ways to share it that are easy and safe. My top priority would be sharing with my health network -- personal trainer, dietitian, physician. (OK, I don't really have a trainer or dietitian just yet, but you get the point.)
It also needs be easier to use data from wearable in analysis tools. By mixing it with other data and visualizing it, I can spot trends and correlations, and maybe even set up triggers and alerts.
I'd love to get some feedback:
