No, with the FreeStyle Libre 3 system you do not need to scan to receive a glucose reading. When your FreeStyle Libre 3 sensor is paired with your smartphone, you will automatically see the latest glucose information after you open the FreeStyle Libre 3 app or when you receive an alarm* notification on your compatible smartphone †.
* 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 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.
