✓ Patients enable the Share feature from their Dexcom G6 app, inviting up to 10 people to follow the glucose data and customise their notification preferences.

✓ Followers simply download the Dexcom Follow app and accept the invitation from the patient to begin viewing their loved one’s readings and receive notifications.
