It is a native iOS App with support for the Apple Watch. Features are: - Define a range of acceptable blood glucose values. - Whenever your values are out of range you will be alerted. - You can snooze the alerts all the time and for a defined time period. - You can reactivate the alerts all the time. - You can activate alerts if the values are rising or falling too fast. - The app displays yesterdays values as an overlay chart. This way you have a hint about how your values could behave in the future. - Tune your basal rates with the statistics function to overlay different days - Sync your bg values to HealthKit (optional) For the alarms to work the app has to be active. So you can enable a screen lock that keeps the app running all night long. Have a look at www.nightscout.info for more information about how to setup your own Nightscout backend.

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.
