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.
