The Apple Watch integration with the Dexcom G7 continuous glucose monitor (CGM) has revolutionized how people with diabetes monitor their glucose levels. Users can now view real-time blood sugar data directly on their wrist, without needing their smartphone nearby. This combination allows for instant access to glucose readings, trend information, and alerts, transforming the way individuals manage their diabetes. 

The Apple Watch serves as a supplementary device for viewing Dexcom G7 data. A compatible iPhone is still necessary for initial setup, pairing, and data sharing. Your phone is also required for a comprehensive view of glucose data alongside other health metrics in the Apple Health app. And, obviously, any user needs to be wearing the G7 CGM sensor. Direct to Watch is available in all markets that have Dexcom G7.

It's worth noting that the Dexcom G7 monitor, as a Class II medical device, is FDA cleared rather than approved, underlining its role as a supportive tool in managing diabetes. To use the direct to watch feature, you need to have an Apple Watch Series 6 or above. If new, you must have installed watchOS 10. You must also have an iPhone running iOS 17 or later. Ok, with that covered, lets get started. 

Step 1.
