When it works, it works pretty good. My BG is pretty spot on all the time. HOWEVER, the g7 constantly loses connection with my phone and I'm never more than 10 feet away. The alerts go off at least 100 times a day. Sometimes I've gone 8 plus hours without being able to get readings ony phone because this thing won't connect! It does however, keep a decent connection with my Tslim pump, which is odd as hell. This app is a waste. PLEASE FIX IT!

I'm on my second G7 sample sensor and both of them keep losing signal throughout the day. I am constantly having to unpair it from my Bluetooth and re-pair it throughout the day. The pairing mode takes a little time to show up and I don't have to start over with those start up videos. My phone is constantly with me, so I don't get it. My readings are off by between 30 and 50 pts. If I didn't have this problem with 'lost' signal, i would give it 4 stars due to readings being off.

So far, I've been pleased with the app. It hasn't crashed on me. It's connected to my sensor like it should. I discovered that I'm able to see my numbers and times by rotating my phone and scrolling over the graph. I'm taking notes to see how different food options and exercise affect my blood sugar and hope to see how my supplements and Trulicity dosage affect it. I've found my number to be a little higher than my finger stick, but not too much different. I just wish I could take screenshots.
