For people with diabetes, the Eversense Mobile Application works with all Eversense Continuous Glucose Monitoring Systems available in the US – the first and only long-term CGM with a sensor that measures glucose for months, not weeks. The app runs on a compatible mobile device and receives and displays glucose data from the Eversense Smart Transmitter. In addition to the current glucose value, the Eversense Mobile App provides alerts for hypo and hyperglycemia based on the settings you enter. It also displays the rate and direction of glucose changes, and provides the ability to enter glucose-related events like meals, insulin and exercise. The Eversense CGM Mobile App is also compatible with the Eversense NOW Remote Monitoring mobile app and the Apple Health app. The Eversense Mobile Application cannot provide glucose readings if not used in conjunction with the Eversense CGM system, including the Eversense Smart Transmitter and Eversense Sensor. The Eversense CGM System is a prescription device, and you should contact your health care provider for more information.
