App not working

It keeps saying to retry

Good but needs Apple Watch app

I would rate 5 stars if it had an Apple Watch app like the Dexcom That vibrates when sleeping for alerts

Loses Bluetooth Connection Frequently

Libre 3 sensor & the app are supposed to be an improvement over previous versions. The sensor is accurate, and the app registers readings in the background now. However, the app loses Bluetooth connectivity quite frequently which the last version never did (in the same phone, same iOS version). Thus is an annoyance that needs to be fixed. Would be great if the app added a widget and Apple Watch support.

Updates remove good features

I have used the Libre sensors for several years. Now using the 3 plus requires a new app. They keep deleting good features, like silent mode, which I use all the time, after eating something to correct my glucose levels. Otherwise the alarms keep ringing, disturbing my wife’s sleep

First Impression -Will update

Right off, there's no way to prevent compression lows and an alarm better not wake me up as I have a hard time sleeping to begin with. Also, there's no overpatch and I'm sure this won't go over well with my employer. I'm going to use it for now. So far, I'm highly unimpressed. If I'd known all this, I would have asked my Dr for something else before I paid for it. Now I'm stuck with it. Right now, the non-prescription Stello has the Libre prescription device beat, right out of the box.
