The FreeStyle Libre 3 sensor captures glucose readings every minute and automatically sends them to your smartphone with the FreeStyle Libre 3 app*. If the FreeStyle Libre 3 sensor loses signal with the app, the sensor will continue to capture glucose readings every minute. Once reconnected, the FreeStyle Libre 3 app will show glucose readings from the FreeStyle Libre 3 sensor captured during the period of signal loss.
* The FreeStyle Libre 3 app is only compatible with certain mobile devices and operating systems. Please check our compatibility guide for more information about device compatibility before using the app.
