The new Apple Watch is able to use an app that can monitor blood glucose levels.  The app was designed by DexCom and can track and display glucose levels in the form of a graph.   DexCom’s glucose monitor will take the form of a body sensor that you wear around your abdomen. The body sensor measures your blood glucose levels every five minutes and sends the information to a remote handheld device within 20 feet.  This device is then able to communicate with the iPhone, which then sends the data to the Apple Watch to be displayed.  The advantage is that you can just look at your watch rather than having to check your iPhone or DexCom’s remote handheld device.  DexCom offers two apps through their Share System; one is installed on the user’s device allowing the data to be viewed by the user; the second app is installed on another person’s device with whom the user wants to share the data—perhaps a doctor or a caregiver.
