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

Update

I hate it every 5 minutes I got a notification that I need to change my sensor, but the sensor is working fine, I can’t take of this notification because they’re the critical notification, now my phone got this notification and it’s really hard to sleep because of that. Please fix it soon
