About this app

Manage diabetes together with the LibreLinkUp app – a tool for monitoring someone's glucose from afar [1]. Now with interactive glucose graphs and glucose alarms [3, 4].


LibreLinkUp allows you to monitor and support people who are using a FreeStyle Libre sensor and compatible FreeStyle Libre app. You can link up by asking them to invite you in their app.

Whether you’re a family member, friend or co-worker, the LibreLinkUp app helps you monitor and support people in your life so they can better manage their diabetes. You can use the LibreLinkUp app to view their glucose with a quick glance of your phone if they’re using a FreeStyle Libre sensor and app.

Innovations include:

GLUCOSE HISTORY AND INSIGHTS: Touch the glucose graph to see recent history, or review a logbook of glucose scans [2] and alarms [3, 4] – so you can better understand glucose patterns
GLUCOSE ALARMS: Receive alerts when glucose is high or low, so you can help them take action [3, 4]
SENSOR ALERTS Get notified when a new sensor is started, and when a sensor and app lose connectivity [3, 4]
DARK MODE: View glucose data in lower-light conditions, whether it’s in a cinema or the middle of the night

Ratings and reviews

I used to really like the app because no matter how often I opened my app I had a numeric reading. Now, there is almost never a numeric reading. I can see the graph, but it isn't usually current. Randomly, if I'm lucky, a numeric reading appears. This app has worked for years so I have no idea what was recently updated to absolutely break the app. I even logged out of the app and back in, as well as uninstall and reinstall it. It is 100% a coding issue. Please restore a previous version.

I use this to help my Type 1 husband keep in range. It worked great at first, but now it constantly loses connections and reconnects on its own dozens of times per day no matter what wifi system we may or may not be on. I've tried to delete the app and reinstall, but that did not fix the issue.

EDIT 2/4/25: I cannot recommend this app or device for Android users. (It may work for iPhone.) LinkUp has not worked correctly for months. Last time I called customer service I was told the issue was sent to Tech and they would contact me. Crickets. My mother's app just updated with a message that it may not work with her phone. A friend is switching to Dexcom because this doesn't work with Samsung 23. As soon as insurance allows, we are switching, too.
