The glucose data is stored in the cloud, not on your mobile device. If you are downloading the App onto a new device, the following data will automatically become available:
The Eversense® E3 CGM System measures glucose in interstitial fluid (ISF) between the body’s cells.Physiologic differences between ISF and blood from a finger stick may result in differences in glucose measurements. These differences are especially evident during times of rapid change in blood glucose (e.g., after eating, dosing insulin, or exercising). On average, glucose levels in ISF lag behind glucose levels in blood by several minutes.
The trend arrow on the My Glucose screen of the Eversense® App screen will give you an indication of which direction the glucose is moving towards, up or down and the rate of change.

The Eversense® E3 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to 180 days in persons with diabetes age 18 and older. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are still required for calibration primarily one time a day after day 21, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense E3 CGM System is a prescription device; patients should talk to their health care provider to learn more.
The Eversense® 365 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to one year in people (18 years and older) with diabetes. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are required for calibration one time a week after day 13, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense 365 CGM System is a prescription device; patients should talk to their health care provider to learn more.
