What users are saying

1. Now I am using the Dexcom reciever again and the whole reason I got the Dexcom G5 is to use my phone to monitor blood sugar levels.

2. While they say that it may take 'several weeks or more', a more accurate response would have said 'several months or never'.I am thinking about switching to a competitor because it is Completely unacceptable that this product does not work with the note 9....it is a Good concept just needs to work better with android phones ! I have had many problems with pop ups and it not being able to connect to my transmitter.

3. If you play games on your phone and turn down the media volume, you are turning down your alerts in the process.

4. I like the idea of being able to use your smart phone as well as your regular monitor but feel like this should include all smart phone users not just ones lucky enough to have compatble phones.

5. I wish they would make this app available on the Samsung Galaxy note 9 It has been out for plenty of time now and still cant be used on the best smart phone on the marketsays device incompatible.

6. My phone has no issues with any other bluetooth device, only the Dexcom Transmitter.

7. Now the app is applicable to my phone and was working fine until just last week when I lost communication with the transmitter.

8. Disappointing to say the leastThe app is convenient, easy to use and a blessing to be able check my bg levels with a touch on my phone.

9. Very good way to keep track of your glucose levels!!! Love it the alarms do get annoying but you can change the level high or low that it alerts you.

10. Also, I have an LG phone (LG 7Q +) and looking at the compatible list, there are very few LG phones even on the list.

11. Then make sure to have your alarms turned back on.Life saving device/app! Unfortunately, there is an issue with alerts, which is the primary reason to use this app.
