Even as a non-diabetic, I imagine a magically-convenient blood-glucose monitor could be very useful for some sort of digital-assistant, alerting our conscious brains to get some food or take a break.
Obviously the most bang-for-the-buck would be anyone operating heavy machinery or doing surgeries or driving, but a little alert could still be useful for office-work or procrastination behavior.
Very good idea. I was under the impression that most phone cameras these days can do very basic analysis and determine blood oxygenation. There probably is a glucose monitor as well and if there isn't then one probably could be built with a bit of AI.
