Read full description

For people with diabetes, the Eversense 365 Application is compatible with the Eversense 365 Continuous Glucose Monitoring (CGM) System available in the US – the first and only CGM device with a sensor that measures glucose for a 1-year period. The app runs on a compatible mobile device and receives and displays glucose data from the Eversense 365 Smart Transmitter. In addition to your current glucose values, the Eversense 365 App provides alerts for potential hypoglycemia and hyperglycemia events based on your individual settings. It also displays the rate and direction of glucose changes, and provides the ability to enter glucose-related events such as meals, insulin delivery, and exercise. The Eversense 365 App is also compatible with the Eversense NOW Remote Monitoring mobile app and the Apple Health app. The Eversense 365 App cannot provide glucose readings unless it is used in conjunction with the Eversense 365 CGM system, which includes the Eversense 365 Smart Transmitter and Eversense 365 Sensor. The Eversense 365 CGM System is a prescription device, and you should contact your health care provider for more information and whether the Eversense 365 System is right for you.
