### 4/5 — Love it but would love an Apple Watch option

*2026-08-25, version 5.1.1*

Like I said in the title, this app is phenomenal, but I would love to have the ability to get alerts on my Apple Watch.

### 2/5 — Alarm not reliable

*2026-08-24, version 5.1.1*

Quite often the alarm does not sound on my parent phone. I find this to be dangerous fault as this could cause a significant medical emergency or even death.

### 2/5 — App not working since latest update

*2026-08-23, version 5.1.1*

App worked great up until the update last week. Since then I haven’t gotten any readings from my husband’s sensor. Very disappointing. I’ll call customer service but it is still irritating.

### 1/5 — No low notifications

*2026-08-22, version 5.1.1*

Husbands app updated last night and now I get no notifications for low blood sugar. His sugar got to 60 before I knew it. Only because his phone went  off and I finally heard it.

### 1/5 — Lost of connection

*2026-08-21, version 5.1.1*

Since the update every 5 minutes or so it keeps losing connection to their libre, before the update app was great but not now. I’m give app a one star once fixed I’ll update review

### 3/5 — Missing data

*2026-08-18, version 5.1.1*

It’s great that my wife is able to share her Glucose chart, allowing me to remotely monitor her glucose levels. However, I don’t understand why I don’t see the same chart she does; hers displays her recorded insulin, carbs, exercise, etc, whereas my view does not, so I can’t tell when I see a spike whether or not she has treated it. Conversely, if I see a sudden drop, can’t tell if she inadvertently administered too much insulin.

### 2/5 — It’s only good for current numbers.

*2026-08-17, version 5.1.1*

I’m very disappointed with the severe lack of data in the link up app. I’m a caregiver for my mother and I barely have any data to work with. My mother’s phone is the reader for her CGM’s, but I cannot view 1/10th the data her direct app does. When alerts do occur I have to speak to my mother directly to find out why we are getting alerts.

### 3/5 — Language localization issue

*2026-08-12, version 5.1.1*

Hello,

I would like to report a language localization issue in the LibreLinkUp app.

I am currently in the United States and use a U.S. Apple ID. My iPhone’s preferred language order is:

1. Simplified Chinese
2. English (United States)

In LibreLinkUp, the language is also set to Simplified Chinese, but the app interface is displayed in Traditional Chinese instead.

This appears to be a localization/language-selection bug in the LibreLinkUp app. The app recognizes the language as Simplified Chinese in the settings, but the actual user interface is rendered in Traditional Chinese.

Could you please investigate this issue and let me know if there is a workaround or when a fix might be available?

Thank you.

### 3/5 — Cut-and-paste support

*2026-08-11, version 5.1.0*

Somehow, I think Apple is downgrading the notifications from this app because I don’t get them consistently anymore. It’s frustrating to find out two hours later that there was an alarm.

To the devs, I don’t need your cut-and-paste reply, I’d just like to hear that you will look into this.

### 1/5 — Inadmissible!

*2026-08-08*

Application peu fiable pour la surveillance des hypoglycémies à distance. Cette nuit, LibreLinkUp m’a bien envoyé une alerte à 69 mg/dL. En revanche, quelques heures plus tard, la glycémie est descendue jusqu’à 56 mg/dL : aucune alarme sur mon téléphone, aucune alarme chez la personne équipée du capteur, et aucune trace de cette alarme dans le carnet, alors que la valeur de 56 mg/dL apparaît bien sur la courbe.

Il ne s’agissait pas simplement d’un capteur imprécis : une vérification ultérieure simultanée donnait 193 mg/dL au capteur contre 191 mg/dL en glycémie capillaire.

Pour une application dont l’une des fonctions essentielles est précisément d’alerter le patient et ses proches en cas d’hypoglycémie, une alarme qui ne se déclenche pas est un problème de sécurité majeur. Une hypoglycémie nocturne peut avoir des conséquences graves. Il est inadmissible de devoir surveiller soi-même constamment l’application par crainte qu’une alerte ne soit pas émise.

Sans compter les innombrables : pas de données récentes!

Merci de corriger rapidement ce dysfonctionnement.

**Developer response:** Thanks for the comment - we'll need more information to help with this issue, so please visit www.librelinkup.com/contact-support to find your country's support phone number or to directly submit your comment to support.
