Terrible device

Absolutely terrible device and app. Device spends more time with lost signal than it does reading levels. Unreliable and dangerous, should be removed. G6 was good

The app is okay but

The app is okay but my sensor has failed twice in a row in the span of two days and I have had to call support to get sent a new one. The app is okay but the sensor failing so regularly is not good.

New user

While I am too new to give a knowledgeable critique. I would love to see this app become compatible with CarPlay. So I can get notifications on the screen when I’m driving! Would be much more useful than all the shopping apps that appear on my vehicle screen.

Still No Fix For The Critical Alerts Issue

FIX THE CRITICAL ALERTS ISSUE!!

Saw there was an update and was hopeful that the bug of EVERY ALERT BEING A CRITICAL ALERT was fixed, but it’s not. That’s very disappointing and disheartening. 🫤 Before this bug, I was actually very happy with this app. But this bug has made everything so much more stressful for an already stressful, lifelong chronic condition.

Direct to Watch takes too long to reconnect

Update Oct 2nd 2026
When will you release the update for IOS 27?

Update 4/4/2025 what happened why did I lose the arrow direction in complications? After the update 11.4 the complications arrow disappeared. Please help.

Update 9/20/2024 updated to new app version. Notifications set to mirror I phone however now the watch has a mind of its own now sending out alerts of high glucose and no way to turn them off???
It doesn’t mirror the phone. There are no alreats on the phone yet the watch has alerts. This is ridiculous update. How do you shut off the watch alerts? I can’t be sitting in a meeting with the watch having a mind of its own?

Update 6/17/2024. If you turn off the direct to watch feature and go back through the set up it connects right away. Why does it struggle to reconnect after a watch charge or shower when watch is not in the bathroom with you? It is constantly search and have notice the watch’s battery life go way down. There has to be an easy fix for reconnection. Please help!

I have updated the Dexcom g7 app to allow for direct to watch connection. Initially it took a while (hours) to show it was connected directly. Once it did it was great. No more looking for your reading and see this “—-“ constantly. However if you charge your watch and happen to get to far that it looses connection it literally takes hours to reconnect. The other thing I have noticed is because watch it looking for Bluetooth after lost it drains watch battery faster. PLEASE fix the reconnection feature of the app for direct connection. I have literally been waiting overnight 10 hours for a direct reconnection.
