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

I really wish that I was able to go into log book and see if they’ve added any notes or food/exercise. My son likes to add his manual glucose reading as a note as Libre won’t let you calibrate. We’ve noticed libre is consistently 20-40 mg/dL lower than his actual reading and it’s good to know he’s not actually low when his Libre reading is low.

My friend’s blood sugar goes into the 40’s after getting COVID. There have been some case studies on it, Google “COVID 19 and low-glucose levels: Is there a link?” So, his Dr. prescribed him a CGM. Anywho, it is imperative for his life that a buddy helps monitor his blood sugar because he could go into a coma and die. He’s gone low in the middle of the night several times and I’ve had to call him to get up and chug a soda. Scary stuff.

Well, the app keeps randomly logging me out and doesn’t notify me that I’ve been logged out. He’ll go low and I have no idea. I called customer support and they kept trying to blame everything but the app because “it’s not supposed to do that.” They blamed my iOS, my phone, the update, everything but the app developer. Also they told me their “higher department” can’t email me and will call me tomorrow at a random time from a random number and that’s the only way to follow up. I work and can’t just answer whenever they call. How awful is that customer support!

I deleted and re-downloaded the app, noticed the 2.9 star rating, and started reading reviews. THIS HAS BEEN AN ISSUE FOR AT LEAST AN ENTIRE YEAR!! Reviews from a year ago, Feb 9th, and July 21st all say the same thing trying to warn about this dangerous glitch! THIS APP IS GOING TO KILL SOMEONE IF IT ALREADY HASN’T and the company has been absolutely negligent to not heed the warnings. BEWARE.

Want Data Upload to Cloud Desktop Spreadsheet

I have the Abbot Freestyle Libre 14 day CGM system and generally love it. I use both the handheld meter and or cell phone yellow Libre app to capture and display data and analytics from the arm patch stick-on device.
I want the ability to pull ALL time stamped glucose data from the system and place it in tab delimited form into my desktop computer for my own viewing and analysis. ALL data both the minute by minute data held by the patch and the user initiated recordings. .... Does the doctor system do this? Can I get it from my consumer system? Does the “family” app somehow allow this? The data is there and it moves around through your proprietary software and networking. Can the consumer get it? The current system does not allow me to show my endocrinologist specific events over the past several months. I want the full raw data.
