There is currently no app in the FreeStyle Libre family of products that is specifically for smartwatches. However, some smartwatches mirror the notifications received on a smartphone and these smartwatches may receive alarms* and other app notifications.
* Notifications will only be received when alarms are turned on and the sensor is within 20 feet unobstructed of the reading device. You must enable the appropriate settings on your smartphone to receive alarms and alerts, see the FreeStyle Libre 2 User’s Manual for more information.
