I finally decided to order the apple watch with the thought in mind that the sensor for the heart rate monitor will be opened up to developers hopefully when they launch the sdk later this year , I am typ 1 diabetic and do believe in non invasive tech to measure blood glucose is getting more and more possible and I have read that there are already devices out there that use infrared to measure blood glucose. So with that in mind does anyone else think it may be a possibility I know it's a long shot I was just curious if anyone else might think it's possible.
