Signal loss
For a couple of sensors I’ve had the sensor not updating until I put my iPhone up to the CGM itself. Of If I just open the app there no update. After I have updated it and closed my phone and then reopen after a short while I have to put the phone up against the sensor to update the readings. This has happen for 2 out of the last 4 sensors I’ve used
I’ve done a LOT of troubleshooting but once it starts to happen I have to put up with it until I change the sensor. The huge drawback is no alarms are available once this issue starts occurring and it’s not continually communicating with the sensor.

Granular data needs IMPROVEMENT
Edited. I gave up on Libre; far too frustrating to use the app. Switched to a different brand (Ottai). Their app is better and sensors are cheaper too. I get the impression that Libre are coasting- lots of stock responses in the reviews (“thank you for the suggestion we continue to improve the app” blah blah), yet no apparent improvements. Hence trying a different brand.
Sensor is good. As other recent reviews suggest (repeatedly), the data presentation in the App itself is mediocre at best.
The graph homogenises the data far too much. The alarms work, but when acted upon and glucose levels are corrected, the alarm event is usually erased from view.
The time axis on the graph is too broad, leaving you guessing what time period you’re looking at, unless you keep adding manual notes just to highlight things. Graph should have a cursor or interactive option to access detailed information.
Overall the key function of managing glucose works, (top marks), but the rest of the interface is sadly lacking and could (easily ?) offer much better management options.

Flaw in software
Don’t get me wrong, the product is great and has literally saved my life more than once in the past weeks. What I have found is when the software triggers an alarm I.e. low glucose, I have found the sensor / software comms often goes into error. This has two outcomes, firstly you panic and almost overdose on glucose; secondly the sensor starts functioning again after 10 minutes and shows an average which has deleted the recording of the alarm. The recording of the alarms are vital when it comes time for medical reviews and the adjusted average shows the disparity between reality and conceived average.

Great Tech But Mediocre App
The technology in the patch is truly amazing but the app is mediocre at best. The app should be better using the data it collects to help diabetics control their blood glucose levels. The daily graphs are hopeless. We should be able to get a landscape view of the graph with the ability to scroll and zoom to get a more accurate view of the information. Given the data passed to the app, why is there not an option to download it in something like a CSV format for more detailed analysis. Instead of having to reach for the smartphone all the time, why not take advantage of the Apple Watch as a truly convenient method of viewing current blood glucose levels. Please support diabetic patients better by providing an app that takes full advantage of the patch data. Apps nowadays could easily provide all of the above functionality.

Glitchy and appalling customer service
My endocrinologist recently managed to get me to try these. I was apprehensive but thought I’d go for it because they sounded liberating and accessible. I should have known, though, if it sounds too good to be true…
I kept getting signal loss notifications, even when the phone is in my hand. I tried to troubleshoot with whatever recommendations were provided online to no avail. I finally contacted the company and the rep on the phone was shocking. She told me this was not their problem but mine, they are aware there’s a problem with the sensors not being compatible with iOS devices but that’s not their problem and that I should do my research. I asked if they had made this information available, and she said no but it will be made available sometime in the future. I then pointed out that if I had done my research as she’d said, this information would still be missing and therefore they’re misleading people into buying a product that isn’t doing what they’re promising. She said that’s not her problem, the sensors don’t work with Apple devices. She said I should get a new phone if I wanted to keep using their sensors, I said I was on the latest model and the app was updated as well, so what does “new phone” mean? Once again, she points out that it’s not her problem. I said I’d spent a lot of money on sensors that aren’t working and that I had used up my last sensor and will not be using their products in future. She said she will post me 1 replacement sensor and I better not call again as they don’t give freebies. I said What’s the point of sending me a sensor if it won’t work, She said she’s being kind and sending me a reader as well at no cost. I told her it’s of no use to me as I don’t want to use these products in the future especially if they come with such services, she said that’s a good idea and hung up. It says a lot about the company and its products if its employees behave this way.

Signal Loss Issue! – Needs Urgent Fix
This is a serious ongoing Issue When Starting New Sensors – Needs Urgent Fix ASAP!
I’ve been using the Libre2 system for over 24 months now, and while the day-to-day communication between the app and the sensor is generally solid, there is one persistent and extremely frustrating issue that has been completely ignored: signal loss after starting a new sensor.
For the past 6 months, every single time I apply a brand-new Libre2 sensor and initiate it using the LibreLink app, after the 1-hour wait period, I am hit with the infamous and infuriating “Signal Loss” message on screen. This only occurs when activating a new sensor — not during normal usage — which clearly points to an app-side issue rather than a device fault.
The only fix? I have to delete and reinstall the app every single time. That’s now 12 times in 6 months. Once reinstalled and logged back in, the app picks up the sensor immediately after the first scan, and the automatic readings resume as normal for the full 14-day sensor life. So why is this unnecessary step still required?
Frankly, it’s beyond a joke now. This issue has been well documented by users and clearly remains unresolved. It disrupts what should be a seamless experience for users relying on this system for their glucose management. This is not a minor inconvenience — it’s a major flaw.
I had previously rated the app 5 stars because when it works, it works well. But until this persistent sensor start-up communication bug is properly addressed and resolved, I’ll be leaving this lower rating as a reflection of my experience.
Fix this, and I’ll gladly update my rating accordingly.

Increasingly frustrating
I've been using the Freestyle for years now and the 2 was a big step in functionality, with its bluetooth connectivity. I have found though that the sensors are increasingly faulty, and over the past months have had sensors stop working entirely, bluetooth die and adhesives fail. Of the past three sensors, two had the bluetooth stop working within 10 hours of activation, meaning they had to be manually scanned and it's now becoming frustrating. When they work, they are great but when they don't or stop entirely, it's more than a nuisance, especially with Type 1.

Brilliant but a few snags
Love my Libre Sensor 2. Made a big difference to my glucose controls so thank you! A few minor glitches still need fixing please if you can;
1). When recording a voice message in Msngr or What’s Ap, if the alarm goes off the voice message is either lost in Messenger completely or paused in What's Ap.
2). Alarm red tag gets stuck on and I have to go through several cycles of turning it off before the red tag clears.
Other than that I love the numerous features you provide and I find it very easy to use and use it regularly to review my control methods with my diabetic nurse.
This sensor has taken my diabetes to a whole new level I never thought was obtainable before in my 38 years of being a Type 1 Diabetic. So thank you again!

Automatic Glucose Monitoring only works sometimes
Recently with the new update Abbott advertises automatic glucose monitoring, but this feature only works like 50-70% of the time.
Usually it looses connections overnight and I have to rescan; but recently half way through my current sensor my phone just completely lost the connection. While I can still manually scan, the sensor no longer sends anything automatically. Retapping doesn’t resume the function either. Sensor doesn’t show up in the Bluetooth devices like it once did.
While I appreciate the attempt of auto glucose monitoring, this functionality still needs work. Until it’s improved my review will stay at 3 stars.

Frustrating
I have been using this app for nearly 2 years now. It’s fantastic when it works and I wouldn’t be without it until now. I have recently used 3 of my sensors because the app won’t connect. I either get scan error please try again or absolutely nothing. I’ve phoned Apple and they assure me it’s the app not the phone (through diagnostic feedback results). Abbots are sending me a separate reader as back up and have now resorted back to finger pricking. This is incredibly frustrating as I am without sensors and do not know if the next one will work either. This will be the 6th sensor I have sent back as faulty. NDDS and Abbots have been very supportive but believe the problem is with the developer. I sincerely hope this connectivity issue will be resolved.

Sensors are faulty
I am a 13 year old who started using Librestyle sensors at the start of the year, when I have an elder help me up it in it works fine, but I follow the correct instructions and every time it ends up not working, tonight I was 4.9 and had a snack and hours later tested my sugar, it’s said LO which means it’s apparently very low, my graphs were also red showing that I was low, I had the food for hypos and tested after a couple of minutes and it still read as LO I tested on my machine (the normal testing machine) and my sugars were 15, I think it’s because my sensor hit a wall, it read my sugars wrong which put me in danger, this isn’t the first time I have had my sensor mess up on something and I am scared for my health, I’m scared that one day my sensor will mess up and put me in a dangerous position like it could have today, for now I am fine but I don’t know If I’m ok yet.
This problem should be fixed so we don’t get put in dangerous situations.

Laggy and more
App lags after sometimes only 1 day:
-click “scan” and there is 1-2 (or more) seconds delay before scan window comes up. Same can apply to adding notes, switching between daily graph, logbook, etc.
-lag gets worse and worse with time. Closing and reopening app “resets” this lag - as others have said - but then after time using it again, the lag creeps up and gets worse and worse.
No functionality to tilt/rotate phone and view graph over wider area. 24 hour graph constantly looks “squashed” and makes glucose levels look far more “spikey” than they often are.
No option to add other metrics when recording food. Grams of protein? Fat? With each meal.
Comments and general translation of recording information does not translate well to reports. Info often gets squashed together -if 15g carbs is recorded, then say another 15g carbs recorded 15 mins later, they are lumped together as one 30g entry in the daily graph printout.
Yeah the CGM technology is great, what a time to be alive, let alone diabetic. Whatever. There is far more opportunity for this software that is simply not being realised or implemented. This has now been in use by the public for long enough for there to be updates to the operating system that are not just cosmetic.

Only worked for the first 4 hours
After purchasing the liber pro from there online store the device arrived shortly after, the instructions were clear and on it went to only last 4 hour then the error message appears and the divide stopped working. Called there customer service to be told that they require a medical practitioners letter, to be able to get it replaced meaning another consultation fee to get a letter for something I’ve already paid for. All this after customer service somewhere in Bombay ticking the boxes with her responses and totally not getting that all I wanted was a replacement device that only worked for 4hours. Then came the pointless emails, so to just stop the unprofessional behavior. I demanded a full refund, 3 weeks later and still waiting with no contact. These device’s are a scam don’t waste your money and go elsewhere. Total waste of money and time.

Timezone out of sync
I’m trialling this for the first time. It worked fine for a day and the device dislodged so Libre sent me a replacement device. However now the app with the replacement device is showing the incorrect Timezone. I called Libre support, however they told me it can’t be changed! Really?! I find that very hard to believe. They said the issue is with the app developers. So I now have data and graphs that are incorrect, out of sync with the time on my phone (AEST) and where I live. It’s only an hours difference but I can’t believe this could happen in this day and age. There are other time zones in Australia that are 5 or 6 hours different to DST.

Tech is great, app is poor
It’s hard to fathom how they could produce such a great product and not care about making an app without multiple critical bugs. Surely the app development costs would be negligible for them? If the ‘check glucose’ button ever doesn’t respond that should be considered a critical bug and yet the app usually takes at least a few seconds before responding after its opened. What’s worse is that it gets slower the longer the app has been running, that indicates a memory leak, which is not good. And to top it off, every few days the check glucose button fails, and then continues to fail. Not even restarting the app fixes the issue, I need to restart the phone! Too bad if I think I’m having hypoglycaemia! Perhaps you should forget about the graphs and reports until the most primary functionality actually works consistently, doesn’t seem too much to ask considering how expensive the product is right now.

Great app, but has become buggy
Love the app, so handy to track your readings electronically with something you always have on me. Pretty accurate.
Only downside is since updates for the past few months it doesn’t always read the sensor quickly, even when directly on it. Never used to have that issue. Deleted and re-added the app which fixed for a week or two, but issues returned. Also lost the history in the app when deleted and reinstalled, even though the data is available via my login, it can’t be seen on the app. Things like estimated A1C don’t work without the history being there.
Other than that, great tool and I’d be lost without it.

I have a request for a feature to be added to the app if possible
This app is great. I use it very often & yes it can be slow to scan but this is usually due to the placement of the phone when scanning.
The only feature that is missing from the app is the option to add a manual blood glucose test add note option. You can only add a manual note to put in insulin delivery, food/carbs, activity but no option to add a manual blood test note. The only way you can do this is to create a note with insulin details, carbs & activity & then in the comment section write the reading in there but when it goes to the lib review page it’s only a note & is often lost & if anything happens to the testing machine it can’t be fixed just for those who don’t down load both phone & meter data to the site.
Great app & recommend it to everyone as the go to product but if the developers could add this as an option it would be pretty much perfect.
Keep up the great work! 😊

Thanks for the suggestions. We are continuing to improve the app and we will look in to this.
Brilliant functionality, in need of iteration and UX improvement.
This technology is ground breaking for diabetes and pioneering getting this on apple. The app is functional, without getting into nitty gritty complaints the biggest UX issue I have is the graph axis’s have been designed with portrait mode in mind versus how diabetics usually interpret blood sugar graphs, including that from the LibreLink reader. Just because there’s real estate, it doesn’t mean it’s best used for the graph. The vertical axis is WAY over exaggerated and makes your peaks and troughs appear two to three time more severe then they do compared to how one normally views and interprets data or any normal graph layout. This causes an immense amount of anxiety and overreaction when testing using the app.
It’s to the point where I would rather carry the librelink then use the app, even though the integration and technology is excellent. This poor choice of design has had a large negative effect to myself and likely many others. Many overactive hypos or stress because graphs aren’t mean to be designed in portrait.
I founded a User Experience Design agency with a large team that designs for enterprise and understand how hard design can be. Perhaps it’s just me, but I doubt it. I would like your design team to make efforts to validate the graph design issues as I have seen other comments echoing the same issue. Thanks.

Thank you for the note - we will look in to this.
You must click the ‘Check Glucose’ button every time you open the App.
I read my Freestyle sensor MANY times every day, and EVERY time I open the app I must press the check glucose button before performing the scan. It would make much more sense if the app defaulted to performing the scan, with the option to cancel out when you want to access other features.
Maybe 20% of the time you get errors scanning and you must repeat the process, which is weird, because that just never happens with any other Bluetooth LE devices that I use, nor with the freestyle handheld meter.
Otherwise, pretty good, and my preferred glucose meter out of the main players. Quite accurate, only a little lag.

Pretty good
The colours that indicate in-range or out-of-range are a surprisingly helpful addition, compared to the reader. The sounds appear to be the same when there is a successful scan or an unsuccessful scan. This should be changed. Maybe these options could be configurable by the user (similar to the reader) so that, as a further option, you could set it to vibrate rather than make a sound. Which I think helps with privacy issues as some people don’t notice a vibrate but definitely notice a ‘beep’. The only real drawback is the inability to share the data between the reader and the app, so I’m trying to remember to scan both every 8 hours, as I find it easier to use the reader in the middle of the night or while driving (when you can’t touch your phone). So glad that Australians can now use this app.
