The FreeStyle Libre 3 system offers optional Low Glucose, High Glucose, and Signal Loss Alarms*. The FreeStyle Libre 3 app** also has a mandatory Urgent Low Glucose Alarm1 that lets users know when their glucose value is below 55mg/dL.
* Notifications will only be received when alarms are turned on and the sensor is within 33 feet unobstructed of the reading device. You must enable the appropriate settings on your smartphone to receive alarms and alerts, see the FreeStyle Libre 3 User's Manual for more information.
** The FreeStyle Libre systems apps are only compatible with certain mobile devices and operating systems. Please check the Support section of our website for more information about device compatibility before using the apps. Use of the FreeStyle Libre systems apps may require registration with LibreView.
