### 5/5 — An Excellent App

*2026-08-12, version 5.0.0*

I think app is fantastic. It works very well and I can see my blood sugars on my watch very clearly. I am very grateful to the person who put the app together it makes a big difference to my daily life and trying to control my diabetes. ThANK YOU

### 5/5 — Libre 3 plus user

*2026-07-04, version 5.0.0*

I’ve really like this app. I totally overlooked the add data to apple health in the options. This app is providing two functions that were not included in the Libre app. Very good job for a solo project.

### 1/5 — Can’t log in

*2026-05-30, version 5.0.0*

The app worked for a while and I loved it since I was able to get the Libre 3 reading from my S25 ultra onto my iPhone using this app! For some reason the app no longer logs in using my Librelinkup credentials. I changed my password for the Librelinkup several time and it still won’t log in! The Librelinkup works fine on both my iPhone and S25 ultra. I am now using the iPhone to connect to the Libre 3 plus CGM, but I would like to use this app to connect to my Apple Health.

### 3/5 — Good Application

*2026-03-29, version 5.0.0*

Seems at first glance that it’s a good application with many different watch complication options.
The new rectangular complication will not automatically update.(works when forced)
This application seems not to be supported because the developer is not responding to my emails.

### 4/5 — Great Application

*2026-03-19, version 5.0.0*

Good application with many different options. 
Well done developer.
The new rectangular complication will not update.
Is this application supported as the developer is not responding to my emails.

### 2/5 — Apple Watch

*2026-03-08, version 5.0.0*

The app wants me to log in using my watch but won’t allow me to enter the password on my iPhone. I have a 25 character password which is almost impossible to enter on the watch keyboard.

### 1/5 — Purchased is grayed out

*2026-02-28, version 5.0.0*

Purchased is grayed out and won’t download.  Did as instructed on Apple Watch, nothing.  Completely worthless.

### 2/5 — Not for Dexcom

*2026-02-21, version 5.0.0*

This was my mistake tbh it sounded just like what I needed for my Apple Watch and I rushed to download it then realised it’s only for libre.  Hopefully something similar becomes available for dexcom

### 5/5 — Works for wonderfully

*2026-01-02, version 4.7.0*

This is a really well put together app that works very well, I love the complication it offers for your watch faces and it just works, not much else to say about it except thank you for making it.

### 5/5 — Fantastic tool

*2025-12-24, version 4.7.0*

There are so many situations where checking your numbers on your watch is so much easier and safer than using the phone, this app is so important to my life, love it
