Each FreeStyle Libre 2 app* alarm† is accompanied by a phone notification which will describe the type of alarm that is being signaled. There are three different sound notifications for each the low glucose alarm, the high glucose alarm, and the signal loss alarm. The user will be able to audibly tell the difference between these three alarms.
