Optional Alarms1

with the FreeStyle Libre Systems

With our optional alarm function, you can choose to receive a message the minute your sugar level is too high or too low using the FreeStyle Libre systems.

 

How it works

When you turn on the glucose alarms, you'll receive a notification when your glucose reading goes above or below your target range2.

It even works when you're sleeping or when your smartphone is in Do Not Disturb mode. When you receive a glucose alarm, you can tap the notification to immediately check your glucose level and take necessary action.

Setting the alarms on the FreeStyle LibreLink app is just the first step. Next, you need to make sure your smartphone has notifications enabled for the app. If you didn't enable all notifications and permissions during app set up, how you do it now depends on your phone's operating system.
