What is the LibreLinkUp app?

LibreLinkUp1,4 is a free mobile app that allows family, friends, and caregivers to receive glucose data from Connections who use a FreeStyle Libre2,3 app with a FreeStyle Libre sensor.

Once you have installed the LibreLinkUp app and accepted an invitation from a FreeStyle Libre app user to connect, you will receive their glucose data on your smartphone.

LibreLinkUp users who are following Connections that are using FreeStyle Libre 2 or FreeStyle Libre 3 system sensors and a FreeStyle Libre app can also receive glucose alarm data and notifications5, 6, 7.

What causes glucose alarms to be unavailable?

Connections may have the option to use a Sensor with multiple devices. If you Connection starts their Sensor with another device, including their Reader, you will not receive glucose alarms.

You will only receive glucose alarms if you Connection starts a new Sensor with their app.
