Apple is close to adding a glucose monitor to their Watch!

This is very cool. Assuming it's sufficiently accurate, this will be a heck of a game-changer for diabetics. And accuracy is pretty important for this! My Apple Watch does a three-lead ECG to check for AFib, measures my pulse, and SpO2. The pulse and SpO2 results are very comparable to my BP machine's reading and a finger pulse oxymeter with both devices measuring pulse rate. Of course, the accuracy of home medical equipment vs the equipment in a medical practice is always subject to debate.

Temperature is expected to be added at some point. People would like to see BP measured by the watch, but that's very difficult as normally that's measured by a vein being listened to collapsing and re-opening.

I don't know how critical spot-on accuracy is for diabetics.  Would a 5% swing be close enough?  Do they base how much insulin to inject based on these readings?  I don't have any first-hand experience with diabetes.

I don't have first hand experience, but for things like insulin, the reading is very important to the dosage needed. And to figuring out what direction to go in for correcting into a good sugar level, by adding or taking away. So less swing is better.
