Dexcom G6 Customer Insights

1. As somebody who runs a lot I was really looking forward to the ease of being able to monitor myself while running without having to pull my phone out but this has been a flop.I can't enter text for events or scroll back several days or weeks.

2. Allow me to acknowledge and silence alerts without opening app.It does a great job monitoring my glucose levels BUT (and you have to do this using your glucometer and sticking your fingers), it has to be calibrated at least twice a day, and even then it's readings have been 10 - 60 points off.

3. My watch screen is completely black, or it won't connect to my dexcom readings on my phone for hours.

4. It sucks, I have to leave my work area, dig out my phone, remove my gloves, find the notification, open the app, wait, acknowledge, then switch to my media and restart.

5. I need to be able to enter info about my events like what meal and be able to write exactly what I ate like it does in the libre 2 app.

6. Dexcom went out of their way to PAUSE the media instead letting the phone mute it, like every other app.

7. Emails to developer go to unmonitored email account.Three times they disqualified the phone I was using, forcing a new purchase.

8. I appreciate that Dexcom has come out with a compatible watchface that accurately tells the glucose readings via Bluetooth directly from the transmitter.

9. It would be great if it were possible in future releases to have the numbers available as a complication for other watch faces.

10. Do you have money to waste? Lately, it loses connection to my new Samsung phone forcing a bluetooth repair.

11. Just pull data from the app instead of making me fill all the info in each time.
