The Dexcom G4® Platinum Receiver with Share™ can sync blood glucose data to Apple’s Health app. Using the TrainingPeaks Mobile app for iOS you can graph blood glucose data stored in Apple’s Health app alongside your training data.
This feature must first be enabled. This can be done under App Settings. Note that this feature is only available to athletes.
Open the TrainingPeaks app. Tap the top left settings menu (looks like 3 stacked lines), choose Settings.
Tap the option to "Read Blood Glucose Data from Healthkit.
On the next screen, allow TrainingPeaks to read Blood Glucose Data.
Once enabled, blood glucose data stored in Apple’s Health app will automatically be graphed alongside your training data. Each blue dot on the graph represents a single blood glucose reading stored in the Health app. Using the tool tip you can view the exact blood glucose reading at that time.
