It appears that Dexcom G7 does provide readings directly to Apple Watch, but Libre never has. Is anyone aware of an application vendor who is developing a direct to Apple Watch app for WatchOS? Is that capability limited by Abbott and is it a security problem or is it a matter of Abbott limiting access only to their LibreView servers and will not allow access by the Apple Watch, directly?

How many of you have a libre 3 plus sensor in America and also how much do you have to pay for it? I am looking to sell mine on ebay (will also sell to the uk) I have a boat load of them and don't really use them as I only have an old phone until I upgrade

I'm new to the Libre 3 app and have some questions.

How do I get the app to show my actual glucose reading in the notification instead of the useless "tap here to open app"?

On the home screen, how do I change the scale of the x axis so I can see more detail? For example only show 3 hours instead of 12.

My phone is already set to dark theme but the app ignores that. How do I switch it to dark mode?

The phone is Android.

I’m forced to go back to pens because my Omnipod 5 isn’t working two out of three times now (have I developed lipodystrophy or resistance everywhere? I apply cream, change injection sites, but I don’t know what else to do). Since I have to go back to basal insulin, I’d like to know which one carries the lowest risk of hypoglycemia and offers the most freedom to “customize” the dose. I’ve heard that some people split the dose in half, using half at night and half during the day. Which insulin works well with this approach? The ones covered by my regional health plan are: Tresiba, Toujeo, Lantus, and Detemir.

My numbers were extremely every night around REM sleep. 300 - 380. When I checked with blood they were a 120 to 160 points lower. This was the same into the morning after taking insulin during the night. Still a 120 points difference between the two. (Correction based on blood). This may explain while I was going low in the AM . To much Insulin with the CGM reading. On the low end off by 30 to 40 points. Blood 48, CGM 82.

This could be damn inconvenient if not dangerous dosing for corrections. Forget the GMI INDEX. In the past I found it to be pretty close to my A1C.

Some of my L3+ had glucose signal fluctuations as shown in the above screenshots captured by the iPhone’s Zukka app and by comparing an expiring sensor and a newly applied sensor. They overlapped one day without pre-soak. For the current sensor, the fluctuations have not stopped after 24 hours.

I have no idea what the origin of these fluctuations is. Because the fluctuations are often lower than the steady trace of the expiring sensor, I suspect they were caused by the body’s immune response to the applicator’s needle and the L3+’s filament insertion into the body. Also I don’t understand the dynamic nature of the fluctuations.

Below is a description of how the immune response affects the sensor’s operation:

“A layer of acute inflammatory tissue (containing damaged cells, connective tissue, edema fluid, and immune cells) may surround the working electrode to become a mechanical or physical barrier that significantly inhibits/slows the inward diffusion of glucose and oxygen. Metabolically active cells adjacent to the electrode (red blood cells, macrophages, and neutrophils) actively consume glucose, significantly decreasing the number of glucose molecules reaching the working electrode. Macrophages have been identified as the major cell type producing a “Cell-Based Metabolic Barrier” that limits the diffusion of glucose from the adjacent interstitial fluid to the sensor's electrodes, causing an artificially low sensor output signal. Thus, performance of an enzyme-based electrochemical glucose sensor may be significantly affected by the dynamically changing local tissue environment immediately adjacent to the working and reference electrodes.

The cellular, humoral, and chemical environment surrounding a CGM electrode will start to stabilize within several hours and become more stable within 12 h of implantation, depending upon the amount of initial tissue trauma, ongoing tissue trauma due to body movement, and the degree of immune response produced by the individual patient. Thrombus will undergo fibrinolysis, neutrophils and macrophages will continue to phagocytize debris, and capillary vessels will regain their vasomotor control and no longer release protein-rich fluid into the wound.^(”)

Depending on the individual and location of the sensor, this immune response could last hours to several days: “This delay of sensor functionality, which is also referred to as the run-in time of implantable biosensors and is defined as the time from implantation of the biosensor to the actual stabilization of the sensor baseline signal, can last a few hours to several days.”.

I hope the above references explain some of the complaints on this sub of initial poor performance or early failure of the sensor.

Obviously, these fluctuations cause unwanted errors. It will be interesting to find out if pre-soak could reduce or eliminate these fluctuations.

I cannot find an app compatible with this sensor.

LibreLink, Libre 3, Libre apps do not work.

And the Libre 2 links on Google Play are for other countries.

I have an android.

Any suggestions? Thank you! :)

I made it 55 hours. I was reading in bed, leaning against a giant squishimal that my kid rejected, when suddenly I felt an itchy, bandaid removal type feeling. I felt my arm and the sensor was gone. I found it stuck to the squishimal.

Is there a way to get a replacement? And how do I avoid this in the future? I've seen people with round pieces of tape over their sensors, but I wonder if that would stick to the overhanging tape the sensor attaches with.

I've been having for the past 4 weeks constant sub 12 hour runs with my sensors everything is fine then just "replace sensor" after 12 hours, I'm averaging a 7.5 mmol glucose level and it still dies does anyone know what's going on? Even the replacement ones from libre themselves are duds. Did the quality control at the factory get laid off?

(Preface for those who use Samsung Z Flip7)
I don’t know how often this is talked about, but I’ve hardly seen posts or discussions about this. I’ve always used an iPhone since before my diagnosis five years ago, and I don’t really have many complaints about it, for a time it did suck not having the ability to see trends on the watch, but that’s been fixed some time ago. I’m currently on the Freestyle Libre 3 plus, with the exception of some notification issues my iPhone seems to have I can’t really complain, but recently I’ve been thinking of switching back over to Samsung. I’ve tried searching for videos of other diabetics using Samsung software and their experience with Libre connectivity, but I’ve not seen anything. So my questions are for for those who specifically own a Samsung Z Flip7 and use Freestyle Libre cgm’s, what has your experience been like? Any issues revolving around how apps close or is there a way around it? Or thoughts in general? And phone battery concerns given notifications and alarms from sensors?

I appreciate any feedback, thoughts, and even warnings, thanks!

When I loose connection to my phone, the curve while I was not connected gets filled back in on the graph. There are times when it doesn’t.

What drives the curve getting plotted while you’re disconnected?

Is there any way to go to the pool or beach wearing the libre2 plus sensor and it still be accurate ???

So I have the iPhone 13 mini, and it’s absolute trash after iOS 26. Libre 3 makes it a lot worse. I continuously get sensor disconnects, phone freezing, and phone excessively heating up and draining battery. This happens multiple times a day. Without using the sensor, the majority of these problems are gone and if they happen, it’s maybe once a week. Restoring the phone did not help.

So here’s my question(s). First, how does one obtain the standalone reader for the Libre 3? My next ends appointment is 10 months from now and they have not answered my question over the phone or over MyChart.

Second question, has anybody tried the iOS 27 beta with the Libre 3? If so, does it work? I
I’ve read good things about iOS 27 and would love to try it if the CGM continues working.

Anyone had this problem? ive had this happen twice. I bring extra Libre 3 + in my carryon. I ask for an alternative scanning because Abbott has said not to put them through the milimeter scanner/xray. EVERYTIME they alarm as explosive and TSA wants to open my sterile cgms.
