Alarm

Please fix the alarms for the low blood sugar or just make it to where they only beep once and to where they don’t interrupt other things that are Bluetooth PLEASE I CANT KEEP GETTING WOKEN UP IN THE MIDDLE OF MY SLEEP 🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬

Glitches constantly

Well, my first problem is showing extremely low level levels only to check with a fingerprint to realize it’s not

Keeps reminding me to add a new sensor after I’ve already Added a new sensor, annoying alerts

Was better previously

Constantly tells me I need a new sensor. I’m starting to think they just want to fleece me by making me replace perfectly good sensors. The fact that my glucose is always updated when I get in the app doesn’t reduce the issue.

Accuracy

The sensor is not accurate , I was thinking it would help but every time I get my Lab results I told the Doctor that A1C 6.2 and 7.8 is way off .. it really frustrates me because I am thinking it’s 6.2 when Lab shows another result for A1C ???

Very bad

It’s awful

Alerts

I don’t need critical alerts also if I get out of Bluetooth range it sounds off I’m a type 2 I don’t need that

If I could give a zero I would.

Quite literally the worst app I’ve ever used. Honestly I don’t even know which is worse, the app or the actual sensor. The sensor keeps disconnecting and the app just says lost connection alarms unavailable. I can’t see readings and the ones I do get are way off. I’m always getting alarms for critical low levels which result in unnecessary extra finger pokes for reassurance. The constant annoying unceasing alerts are the worst part. You can’t turn them off.. They kept waking me up at night last night (even if you have your phone on sleep more or do not disturb they still come through) it got to the point where I deleted the app and took the sensor off not even 24 hours after getting it and using it for the first time. I am switching to Dexcom instead because this is ridiculous. I paid out of pocket for this sensor because my insurance didn’t want to cover it and I am not even able to repair it to their other app they have in store to see if it’s any better that this horrible app. They should pull this app off the store so people don’t get confused and waste money time and sensors.

So bad

Managers have DEF ears, sensors have issues after issues. Stop reporting to the Board this is a good product! It SUCKS

Worst NagWare since AOL

Loud, frequent alarms to replace sensor. Even after replacing and activating a new sensor. I’ve had to turn off the alarms, which completely rendered the app inoperable.

Screen does not clear!

Screen does not clear after an entry so you end up with multiple entries that you must restart your phone, bringing the app again to clear multiple entries!

More of a downgrade than an upgrade

Previous versions allowed easier and faster input of carbs, insulin and exercise. Access to reports isn’t as straightforward either. I really don’t like the new design, it feels like a big step backwards for the UI.

Accurate but keeps losing signal

When it works it works great. I keep losing signal however. If you can fix that it works be great or at least have a way to manual way to reconnect instead of just hoping for the best.

Connectivity

I have had the libre system for 2 months now and have 4 out of 6 sensors unable to process the glucose levels with the same unable to connect alert. I am now on my 7th as they have replaced the 4 faulty sensors to no avail. Last chance libre

Dad & Son Can't Use at Same Time

I am the manager of our account on my email. But when I started my sensor it says it took over my son's sensor for his device. Could you please fix this issue where two devices parent & child can't be on the same account?

My app won’t open

I don’t understand it worked just fine up until quarter after nine tonight which is August 7, 2026 and now it will not open

phone battery killer

doesn’t play nice with iPhone 13 mini; per instructions currently removing and reinstalling app OF COURSE it’s requiring I remove the current sensor to continue. Love the alarm going off in the middle of the night with false readings too

Libre 3 plus

Disruptive Alarm System. Contains too many errors and falling off of sensors

Doesn’t mesh as well as Dexcom did

I was on Dexcom a few years ago, and it meshed with Apple health as well as Apple Watch. There was a way to
Show CGM reading on watch face. I’m trying out libre but haven’t found same accessibility.

Shut Up

There is no control over the loud sound or when it goes off!!! Don’t dare step away from your phone. Awful app.

It crashes since the last iOS update

When I updated my iPhone yesterday, the app crashes. It seems to be random, but then I realized it crashes when the sensor updates. Once that happens, if I restart the app, the screen flashes to the app and then the app terminates instantly. The only fix is to remove the app and the app data and reinstall the app from scratch entering all my personal information. This causes it to forget all the history, which is unacceptable. Apparently it wasn’t tested carefully with the new iOS.

Other than that, up to that point, it was outstanding except at the range of the sensor seems to be a little bit limited, which is understandable considering it’s very small size and probably very low power output. The sensor accuracy seems to be reasonable, it’s usually within about five points of my onetouch ultra test unit. it’s clearly within the margin of error because I can test my blood and in five seconds later to test it again and the sugar level will change by three or four points so five points is close enough.

Overall, it’s good if they would fix the crash problem
