Superior to the regular app but...
Has bugs. Often won't sync more than once with apps. Won't display logbook even though log entries exist.

Stopped working
Doesn’t work on my phone since I have done the recent update to ios26. Any suggestions on how to fix this?
2025-08-20
awesome tool for diabetics
seeing blood sugar information in real time,
allows myself and my doctors and family members too.
understanding how
2025-06-15
Wish there was an app for Apple Watch
I’m a developer myself and I know It’s very easy to create a simple app for Apple Watch to display the sugar level. Right now it only notifies if the sugar drops or shoots, but I wish I could have opened it on my watch and monitor from there. Hopefully you add it soon.
2025-05-27
Needs More Features
On the original Freestyle Libre app, the user can add comments including number of carbs, units taken, etc. On this app, you’re not able to see those extra notes and other information available on the original app. This app should have the ability to see those extra notes, which often times has key information to understand different changes in BGL trends. Otherwise, really nice to have the ability to see my partner’s levels.

No native iPad support
How can graphs be analyzed and manipulated on a small phone screen? An iPad native app would be the logical step or provide a means to access data from a browser.

Good - Unreliable - IOS 18.3.1 updated issues?
Does this app and the freestyle libre 2 have issues staying connected with IOS 18.3.1 update on apple? Everytime my spouse scans his sensor, my librelinkup seems to update the time but stays stuck on the same glucose reading for well over 12 hours, until we completely disconnect and had to re-invite. Have been doing that a couple times now the last few days.
2025-02-05
Need a widget
App works great but the only thing missing is a widget

View FreeStyle Libre 2 Readings without Unlocking Iphone
I’m glad that someone developed this app. I’m surprised that Abbott didn’t think that the ability to view readings on the lockscreen is important.
2024-11-27
20 min gap time!
I cannot understand why there is a 20 minute gap time between the current reading and the second last current reading. The lone is filled in but don’t be fooled, there is a 20 min gap there if you look at the time. This would inconsequential if I didn’t use the Linkup to feed my Sweet Dreams app. So basically, missing 3 readings in my trend line for no good reason.
2024-10-22
Needs a lot of work
Too many things to mention
2024-10-06
High Blood Sugar
I need to go. I need it to go off just when it’s low not when it’s high.
2024-09-20
Stopped working ?
I know the sensor is collecting data because if manually scanned it generally shows a history.
However before we didn’t need to manually scan. It read every x minutes. My autistic son could rely on alerts to say if numbers are going too high or too low. And I could see the numbers too.
A couple of software updates and maintenance releases later and nothing works. No data 90% of the time.
Hopefully this release fixes the major issues.
2024-08-08
alarms are ridiculous
add an option to change high/low blood sugar alarms to just notifications. the only way to turn off the alarms is to turn off the warnings entirely, which is stupid.
2024-07-28
Libreview
Very tedious signing up process
List of Privacy rules does not include Canada

No mmol readings?
There seems to be no option to change the readings to mmol, or references to this in the FAQ and getting started guide. When will it be added?
2024-03-28
No one uses a real computer anymote
Sucks that i need a Chromebook to see my readings on a real computer . Lots of apps are diggicult to manage on a 2” screen!
2023-12-29
Lovely to have but improvements needed
So this is great to keep track of my husbands glucose level but there needs to be a volume level in the settings. I just had my airpods in and if I wasn’t partially deaf before I for sure am now! He’s currently waiting for his numbers to go back up from low alarm and in meantime the app will still sound an alarm. Nothing can do but wait and I would love to listen to music without busting an eardrum. There should also be a temporary turn off notification/alarms. That way once notified and partner takes care of it you can open app to keep track or scan sensor if needed and that way you won’t forget to turn it back on. Even if its 20-30 min as I understand turning it off for too long can be a huge safety issue. And don’t mute notifications until either app is opened or the notification is interacted with. Its also depressing to watch my hubby sigh after eating or drinking a bunch of carbs and alarm keeps going off for the next 40-60 min. Again there isn’t much can do but wait.. I wanna turn off notifications now but don’t want to forget to turn back on cause right now just want to listen to music without a high pitched deafening beep while I clean the house and hubby is watching tv. Just writing this review it has went off 4 times
2023-10-27
Ok, but needs more info
Needs to have the same information as the person who wears the sensor. Without info about insulin usage and food intake, it is impossible to calculate how much insulin is required next.
2023-10-24
Notifications not working
This app was great until the most recent update. Since I updated to it, I have not received a low or high glucose alarm from my spouses sensor, and I cannot see any of their historical data in the logbook anymore. So I only have access to 12 hours of information and I cannot look at trends over time like I could before.
2023-10-23
App
I love this app so much because I am diabetic I can track my sugar level

Disappointed
I rarely get my sons blood sugar sent to my device. It’s sporadic and very frustrating
2023-10-04
Bluetooth device
We recently switched from Dexcom to Libre. It’s taking some getting used to but overall we are mostly happy with the system. However the Bluetooth system is not great. We lose signal all the time several times a day. It is inconsistent in notification to family members on the link up app. We rarely had these problems with Dexcom.
2023-10-04
Alarms
Is there an option to acknowledge a high/low. That you can silence alarm for 30 min -2 hrs without turning alarm completely off ?
2023-10-04
Non stop alarms
Ever since the update I am getting alarms NON STOP! Any time my husbands sugar levels get high I get an alarm, but then it continues non stop any time his levels move, whether up or down. It’s to the point I have to keep my sound off on my phone all day because I can’t handle the alarms. BUT, the alarms don’t go off on his phone, only mine. And I don’t always get notified of his low sugars, nor does he. He was in the low 3’s all night and we didn’t get a single alarm for it! FIX your app please!!!
2023-10-04
Updates in LibreLink to
You went and did an update and when you did the update, you screwed it up that I can’t see my wife’s readings. No more all I get are the emergency readings like when it’s low but I don’t get any of the standard readings and I used to get the graphs that are not the graph, but the readings of every every time she did it and now all I get is if it goes low why did you have to keep changing things it was perfect the way it was put it back the way it was then I will give you a five star does that it was fine but you’re getting a one star because there is no zero stop changing things and screwing them up when they’re working make it that people can turn the alarms off and on when they want to and the people helping watch someone that they can turn theirs on and off when they want to but stop changing things it was working perfectly like three months ago two months ago put it back
2023-09-29
Alarms go off constantly
When my partners levels go below the set range, the alarm goes off EVERY time his blood level changes, in any direction.
It is SO frustrating. This didn’t happen before the recent update. Woke us up needlessly five or six times last night.
I like that he doesn’t have to scan it for us to see where its at - AND that makes the constant alarms even more frustrating and unnecessary.
And there is no way to change this that I can see on the app EXCEPT shutting off low alarms all together, which is obviously not good.
What the hell, Abbot?? Please fix this before I chuck my phone out the gd window.
2023-08-29
Apple Watch
Pourquoi je ne reçois plus de notification sur ma Apple Watch
2023-08-16
Graph lags
As a family member, I wish I had more information available to me on this app. When compared with what the sensor user has, it’s minimal.
But the most frustrating aspect is that the graph started lagging 25 minutes behind the logbook. So, a tap result shows up in the logbook, but the resulting new graph line does not.
I have spoken with customer service twice. Once they made up an answer to say it was my WiFi. The next time, they said they would call back and didn’t.
This did not happen in the first week of use. But now it happens all the time.
2023-06-22
New Version
Most if not all users of this app have received a notification sharing of readings will not work on the current version and you must upgrade to the newest version. This great but there is no new version to upgrade to. So we lose the ability to receive readings for those that we care for with no timeline for the new app version?
2023-06-15
Great App!
We use to follow my son’s blood sugar numbers and it works great for us and his team at MAC
2023-06-13
Worked for about a week and now I keep getting error messages??
What’s the point of creating an App if it only works for a week? I keep getting error messages, and it says it’s down for maintenance for 4 hours?? Wth?
2023-05-05
Most frustrating App on my phone
We rely on this information, but the data just doesn't get to the phone or the watch or it comes silently. Totally unreliable now. We are likely to switch to another product unless this gets fixed.
2023-02-08
Crap app
Worked for one day, doesn’t send me the hi/low alerts, only randomly shows me the graphs. I had read the reviews and thought maybe the glitches would have been fixed. Basically a waste of storage on my device as it is no assistance to help manage sugars
2022-09-27
Trends
This must be designed by someone without diabetes. As a parent, being able to see your daily, weekly, monthly trends on a graph saves hours of work and allows you to adjust your child’s meds without the need for complex equations. The way this is set up I have to manually take the data that is available, add it to a spreadsheet, adjust for time, and work out to the trends. I know how to do this and it is painfully labour intensive. I can’t imagine how people who don’t have that ability manage.
All this so that Libre can save a few bucks on programming? At $100 every two weeks you’d think they could throw in this small change.

Déconnexion à répétition
Une déconnexion ce fait à tout les mois pour moi et mon conjoint, qui suivons les glycémies de notre fille . Lorsque nous rétablissons notre connexion avec l’application, les notifications de glycémie scanner par notre fille ne fonctionne plus. Même chose pour les alarmes d’hypoglycémies et d’hyperglycémies.( alarmes activés sur application)
Nous devons recréer un compte et se connecter à nouveau et cela ne change rien. Nous avons même appelé « AppleCare » pour vérifier si le problème venait de nos téléphones. Nous avons du réinitialiser le téléphone pour que l’application fonctionne comme avant…. Décevant!
Nous utilisons le freestyle libre 2 depuis presque 2 ans sur le même téléphone.( iPhone 11) Et ce n’est que depuis octobre 2022 que plus rien ne fonctionne comme il ce doit.

Share Feature Not Working
My wife has the new Libre and I have the invite notification inside the app to accept, when I click it, it does nothing. If I exit the app and open it again, the same notification keeps popping up to accept. 🤷♂️. Is there an issue with the sharing feature that hasn’t been addressed?
2021-10-11
Had potential but is garbage
So hit or miss and unreliable if it works at all. Hugely disappointing!
2021-05-25
Does not work
I have been using the Libre for many years. Was happy to be switching to the new version 2 and getting the alarms. The linkup app worked for a couple of days and then stopped. I could not get back into the app or recover my password. Rude customer service agent when I was trying to resolve the issue. Have been told it doesn't work with the newest iOS version. Me, plus my two teenage daughters use the Libre2 (that's a lot of libres purchased per year!) and the linkup is essential. We will need to switch ASAP to new devices if this glitch isn't resolved.
2021-03-24
Horrible
My partner moved to Canada from New Zealand and is now using the Canadian LibreLink app but when he tries to add me as a connection for the LibreLinkUp app (for which both our locations are Canada) , it gives an error saying “we can only connect people within the same geographic area”. Would appreciate a fix or support
2021-02-21
Unable to register
I was unable to finish the registration process. I could only get to password and was unable to continue the process. This leaves the app useless. I was hoping to see and share this with with my Doctor. I deleted it.
2021-02-14
Canadian / USA users
The Canadian AppStore version of the LibreLinkUp app doesn’t seem to work for “linking up” with someone who created their LibreLink account via the USA app. Regardless if they’ve switched to using the Canadian LibreLink app or continue using the USA version, it still doesn’t work. This should work across AppStores/countries. Please let me know if this will be fixed.
2020-05-22
Won’t display
I am glad that I can at least get notifications .. but whenever my dad tests his sugar, I will get the same notification twice. When I try to open the app, I get a blank screen.. it wasn’t always this way. I’m waiting for an update
2020-02-24
Needs More Information
I am happy with the app and that I can get my sons current reading, however it would be nice if caregivers could see the graph, I would like to be able to see what is going on before his sugars go high or low, but of course, as of now that is only available for the user.
2020-01-10
Worked great for a few days
Worked great for a few days now do not get readings unless I open app and sometimes it is English and sometimes French :/ was depending on this app for peace of mind when my sons away :( can you please fix this issue
2019-06-20
Nope
I get unknown error from the app every time I try to add someone.
In short... totally useless to me.
2019-05-03
Too many glitches
We were hoping to use this to manage and monitor our 14 year old’s T1D. I have experienced continuous error messages, and then couldn’t log onto my account or recover my password. After I made a new account with a different email it worked for a few days and now I’m not getting his readings.
2019-04-27
Worked for one day
My daughter is on a trial with the libre. My wife and I both have this app to be notified of readings. It worked for the first day and then stopped. We get error messages constantly. On both our following devices. Amateur hour software.
2019-02-17
Readings are behind
My daughters readings stopped reading February 15 and it’s now February 17, you need to review your app
