### 5/5 — Game changer!

*2026-08-24, version 1.3.0*

The app has worked flawlessly for me and has  been an absolute game changer in helping me effectively manage my diabetes. The power of constant glucose monitoring as you eat, exercise, and take your meds, has given me extremely valuable insights into how everything affects my glucose levels and has allowed me to improve my glucose management significantly. Before using these CGM sensors my A1C was frequently in the 7.8 to 8.4 range. Now, I’ve been able to bring it down to 6.1 and no more finger pricks!!

### 3/5 — Great app

*2026-08-24, version 1.3.0*

Really easy app to use with my CGM. Although the alarm alerts are never loud enough, I can barely hear it or sometime the alarm does not even go off. Volume is literally always on full blast but audio is very faint or non existent.

### 4/5 — Lost Signal

*2026-08-24, version 1.3.0*

I love seeing my numbers before and after I eat something, but when I go to check  sometimes it’s a process I have to turn of blue tooth try reconnecting this is the hassle! I also wish it lasted longer period of time! But my numbers have improved with a lifestyle change filed by this monitor and app!

### 3/5 — Keeps losing sensor connectivity and very rudimentary data

*2026-08-24, version 1.3.0*

App keeps losing connection with sensor all the time, throwing alarms all the time. The data supplied is very rudimentary just for 12 hours.

### 5/5 — Transforms your life

*2026-08-23, version 1.3.0*

Transformed my life

### 2/5 — Refuses to hold silent alarm preference.

*2026-08-23, version 1.3.0*

Refuses to hold silent alarm preference.  I set it dozens of times. Then alarms. Then I go back in and update it. Repeat. Very irritating and obnoxious esp around others

### 1/5 — App not functioning

*2026-08-23, version 1.3.0*

It keeps crashing and keep saying my account does not work for this app. Should I be using another app and if so, which one ?

### 2/5 — Totally unreliable

*2026-08-23, version 1.3.0*

The most reliable part of this app is that it keeps dropping the connection to the sensor after some two hours of not looking at the app. Which means: you won’t get any low sugar alarms over night. 
Yes, I made all the settings, checked them over and over again, restarted the phone, restarted Bluetooth, etc. but it keeps happening. Developing Bluetooth devices is not a new thing. I would have expected better.

### 1/5 — False drops wake me up

*2026-08-23, version 1.3.0*

Been wearing this for 3 days now. The last 2 nights, it detected a false drop in blood sugar due to me rolling around in bed and set off an alarm at 2am one night and 3am the next. So, now I have to turn off critical alarms every day before I go to sleep. What a pain.

### 3/5 — Simple and limited

*2026-08-23, version 1.3.0*

The app connected with my Libre 3 sensor fairly easily. I wish it had better options for graphing and retaining data.  Raw data output would be _really_ nice.
