Frustrated

I love the Dexcom G7 for keeping me safe, but the notification system is broken. Even with Do Not Disturb or Focus modes on, the app still blasts alerts every couple of minutes. As an avid hunter, I need complete silence in the field, yet I can’t fully mute it because of diabetes. The constant interruptions make it impossible to use my phone for anything else. It gets worse with my Omnipod insulin pump. A single low blood sugar can trigger around twenty-five notifications in five minutes across both apps. This isn’t just annoying; it’s a serious problem for anyone who needs quiet or focus. Please give users real control to silence alerts completely when needed.

Terrible App

Half of the sensors I use don’t work. I can’t stand the repetitive Notifications as if I can change my glucose on demand. It’s a horrible way to monitor your diabetes. Made me want to ignore my condition entirely.

If I say dismiss just go away

I get nagged 3-4 times a day to tell me about technical support. STOP I said dismiss. If I click the button for help I get an invalid page / http 404 error. Whoever made this change clearly didn’t test it or use it themselves

Notification pop up

Omg get rid of this pop up when I’m at work and wanna quickly engage and see my blood sugars this pops up making me having to dismiss wait a few second then read my blood sugars

Needs updates

Dexcom is a phenomenal tool for managing my CF related diabetes and catching my lows before they become dire, my big issues is that you can. Bluetooth Dexcom readings to an Apple Watch but not to a Garmin watch! My Garmin holds a much better battery and works all around better. Please make some updates to the software so I won’t need my phone on me all the time!
