Hey ya’ll. I’ve been using the Libre 2 with my Android phone as a reader for several months, with pretty good results. I use Juggluco as a Bluetooth collector, which shares to Xdrip+ on the phone. There have been a number of sensors which started accurate and ended inaccurate (30-50% off), and a few which became grossly inaccurate and usually self-terminate the sensor session. I’d say the failure rate was 20-30% overall. To Freestyle’s credit, they have replaced the bad sensors without complaint.
Libre 3 is now available in my pharmacy. I understand Libre 3 still activates via NFC but now communicates with the app via Bluetooth without the need for intermediate apps or devices.
I’ve waited for this for a long time, but have some questions/concerns:
-
Is it as accurate or more accurate than Libre 2? I realize the delay and other challenges with interstitial fluid vs. BG readings, but the Libre 2 (and Dexcom) were often within a few points of true BG, especially early in the sensor life. BTW: I test BG using a Contour Next One, which I take to be accurate based on @Eric 's and others experiences here.
-
Is it more reliable than Libre 2?
-
Does it permit calibration? In my use of Dexcom, the sensors seemed to have a lower failure rate, which I attributed to calibration. I think a number of the “failed” Libre 2 sensors mentioned above could have been rescued by calibration. Unfortunately, the Xdrip calibration was only good for up to 20 pts correction, and usually is inadequate after a day or 2, as the sensor drifts farther from reality.
-
Does it allow communication to an app such as Xdrip, Juggluco, Nightscout, etc? I’m not optimistic about using the Libre3 app: I’m expecting a half-baked app with the bare minimum features and very few available user customizations.
