Dexcom ShareTM is a free app related to the Dexcom G4 Platinum system that allows those living with diabetes to share their glucose information with people of their choice.
Up to five others can follow blood sugars in real-time while they are away from the person with diabetes, at any distance. The glucose data is sent wirelessly and securely using a low energy Bluetooth transmitter built into the Dexcom receiver and sent via the Cloud to a compatible device.
The app is free and requires the person with diabetes to have a compatible Apple product. A full list of compatible devices can be found on the Dexcom website.
