BEFORE STARTING YOUR SENSOR

Before you start your Sensor, choose whether you want to use the reader or the FreeStyle Libre 2 app. If you are using the FreeStyle Libre 2 Plus sensor with an Automated Insulin Delivery (AID) System, do not activate your sensor with the FreeStyle Libre 2 app or reader. Please visit your insulin pump manufacturer's website for specific activation instructions.which device you want to use.

Alarms and glucose readings can only be received on your phone or your FreeStyle Libre 2 Reader (not both). [1]

To receive alarms and glucose readings on your phone, you must start the Sensor with the FreeStyle Libre 2 app.

To receive alarms and glucose readings on your FreeStyle Libre 2 Reader, you must start the Sensor with your Reader.

Note that the FreeStyle Libre 2 app, Reader and your Automated Insulin Delivery (AID) system do not share data with each other.

When not using an AID, for complete information on app or Reader, scan your Sensor every 8 hours with that device; otherwise, your reports will not include all your data. You can only upload and view data from app and reader on LibreView.com.

My issue is that it doesn't scanand once it's not scanning properly, the sensor will stop working. Then it tells me to replace it. They are expensive. I can't keep replacing them. I've gotten two back from maker, but I can't do that every time. I think they're going to think that I'm lying,but I'm not. They just stop working. Also, mine constantly says alarms unavailable. Scan sensor. Omg, I scan multiple times, still alarms unavailable. Then change sensor. I hate the Libre2plus system.It sucks!

This app is terrible. Most of the time the readings are false (I had the app read my sugar in the 40s and it keeps saying it's low. I check my meter and it's in the 300s), and you can only mute it for 6 hours. Of course, it goes off at the worst possible times if you walk too far away from your phone. A lot of the time the sensor doesn't work, or you keep getting an error to check in 10 minutes.

if I'm asleep it's too loud man. it's annoying. I really don't care if I'm dying in the middle of the night. I want a way to make this app only vibrate my phone at all times. you have a selection to silent alarms. but not one to just set the alarm to vibrate. it's far more convenient to use this app vs a reader. but your reader is capable of vibrate only. why isn't the app.
