The Libre 1 app was great. Did what it was supposed to do. No complaints really. This Libre 2 app is terrible! Idk if it was rushed or what. The alarm is so obnoxious. If I've already taken action to bring sugar back up or down into range, I still have to listen to the alarm going off several times. Also, 90% of the time I'm having to rescan several times. It hardly ever scans on the first try. I am going back to the separate scanner
