Loved the app in the former version

This is crazy! The old sensors are discontinued, so I had to get the new one. I thought the problems I read in the other reviews were probably not going to be an issue because my sugar is pretty stable. No hi-low alarms for me… well I hate to say that alarm still goes off randomly and at the most inopportune times! I was in a meeting and got a little too far away from my phone. By the time I got to get into the app and stop it, the alarm had gone off 4 times! And when I use the word alarm, I mean it. It is very loud, ear-piercing and startling, not just annoying. That’s great if it’s saving somebody’s life, but utterly ridiculous for me at this point. That being said, in setting you can (supposedly) shut off the alarm for when your Bluetooth cannot connect, like when you’re too far from your phone. So I did that, but it still alarms sometimes for no good reason. No trouble with my sugar, and no identifiable reason for an alarm.

Problem is, I’m stuck. At least for the month, since I already paid for two new sensors. And one more thing, this one is reading consistently higher than the other one did, and I have not changed my very strict diet. I know it’s not accurate enough to make treatment decisions based on this sensor, but it’s still disturbing. We’ll see what my next blood test says. In the meantime I just keep using this sensor and hope it doesn’t startle me into having a wreck while driving. RANT OVER

Needs Improvement

This app is supposed to help improve my blood sugar by constantly monitoring it, but it actually makes it worse. Let me tell you why. Unless you turn the sensoring off all together, it would obnoxiously allow. I understand it’s for my health, but I can not have this thing beeping and going off so annoyingly all the time. I have work, I go to church, I need to sleep. There are lots of places where I can’t just have this thing beeping. You do realize that if I’m high, and I do a correction it takes time for my blood sugar to come back up. But it’ll keep going off, it’ll keep saying I’m high even though I already corrected it. So I just turn it off and then forget to turn it on and miss being more accurate in my blood sugar because this thing is so annoying. Me and both my 2 diabetic friends have talked about it, we all turn it off until we need to test again. If I got a nice silent notification that my blood sugar is high, I would correct it. Vs not knowing at all for an extra 3 hours because I turned it off. There NEEDS to be a setting to turn off the sound and still get notifications. Stop trying to control us so much that this thing has to beep so loud and so obnoxiously when we’re not in target and just make it like a text message so we can choose wether it’s completely silent, vibrates, or alarms. Because I promise you’re doing more harm than help.

Inaccuracy in graph-especially for low readings

I called about this. I have screenshots for proof but they have no way for me to submit them. This morning the scan and logbook show a reading of 73. The graph shows about 130 for that reading. The graph shows the high logbook readings very accurately. But not the lows. I think theres an error in the graphing programming that is not displaying low readings accurately. Everyone i talked to wants to assume its the sensor OR they give you this standard explanation that the graph is an average. If that were the case then the high readings would not exactly match the logbook readings. Unfortunately the low logbook readings don’t display accurately on the graph.

People using this app - DONT make treatment decisions based on the graph - use the logbook which is accurate readings taken by the sensor. Hopefully if enough people complain about the graph they will get a software engineer to look at it. Customer service - i have screenshots if you figure out how i can submit them. I actually really like this much better than fingersticks but lets get the programming fixed to accurately graph your results. Customer service apparently can’t tell the software engineer theres a problem. Might have to write abbot corporate. Probably get ignored there too. For the record, I am an engineer so I know for certain there is an inaccuracy.
