DONT UPDATE THE JUNE/JULY 2026
Don’t update the June/july 2026 update they don’t care about how laggy the app is now that the G6 is retired
The app disappeared from my Apple Watch
The app on my Watch disappeared, and I have no reason why. Still works on my phone, but I rely on it to work on my watch as well.
G6 ending?
-Update-
Based on the automated response below, I think it’s safe to assume that this update will do nothing except remind you every 20 minutes that the G6 is being phased out, therefore it’s best not to do this update unless you want to be annoyed. Continue to use your remaining G6 patches in peace.
— If the only purpose in this update is to let us know that the G6 is being phased out please tell us that! It’s not worth updating if that’s the only difference

I love Dexcom but..
The graph has disappeared since yesterday’s update.
Discontinued but served me well through its lifespan
Sad that these got discontinued, it was a huge breakthrough in diabetes management technology and had a good experience from 2018 to 2026.
R.I.P G6
Dexcom canceled G6 if you have some still you can use it or you switch to G7. R.I.P G6
Years-long bugs and unreliable alerts
I’m wearing my last G6 sensor before I switch to the G7, but figured now is as good of a time as any to leave a disappointed review of the app.
On the positive side, I am grateful that this technology exists, and that when the sensors fail (as they do about once a month on average), the company is usually accommodating with free replacements. Dexcom Clarity is also a highly useful element of this product, but this review pertains only to this app.
Unfortunately, the alerts, which are the most crucial features of the app, are somehow both unhelpful and startling at the same time. I wish there were a way for me to acknowledge high or low alert early if I know I’m going to get one in a few minutes anyway. There’s really nothing like knowing my blood sugar might go out of range and wanting to silence that notification early, but having countless interviews, classes, etc., interrupted by a noise that disrupts everyone around me in a 50 foot radius. Not to mention how, although I have rise and fall rate alerts turned on, they only notify me after my blood sugar is out of range when the rise or fall rate was already significant almost an hour before the app made me aware of it.
The integration with iOS is also disappointing, because Siri has extreme limits on what information she can share with me, and the widgets rarely have real time data. The warm-up time being two hours long is extremely inconvenient for people who rely on this technology so much. My sensor will end at 110, but the next one will begin at 254 as much as I try to prevent it.
It’s also concerning that when there may be an issue with the sensor, the app is extremely generous on guessing the glucose values, often insisting that my blood sugar is up to 200 or 300 points above or below my actual glucose reading.
Lastly, my app has had a bug for about five years now, that no iOS, app version, or iPhone model upgrade has been able to resolve. When launching the app, the orientation of the graph sometimes flickers from horizontal to vertical back-and-forth several times, and usually lands in an orientation that glitches so badly that most of the indicators and buttons are invisible. This happened about once every day or so for the last five years, and requires me to quit and reopen the app in hopes that the glitch resolves. Nobody on tech support knew how to resolve it.
The graphics used to illustrate the sensor in the app are poor and could have easily been improved by a few hours redrawing them in a vector program.
Even the features like “add event” are not intuitive, and I didn’t feel inclined to use them at all in the last 10 years.
When looking at the color scheme, feature placements, fonts, and symbols, this app has never looked better than something a design intern could have whipped up in Figma with one day of training. It’s truly abysmal for a company that is so uniquely positioned in the market, is trusted for critical medical information by so many people, and charges hundreds or thousands of dollars for their products every month. I look forward to switching to the G7 soon, but I am desperate for a completely different experience than what I had with the G6.

Unreliable
Unfortunately after 3 years of use this has been more of a challenge then a help with managing my blood glucose.
After calibration it will have its periods of inaccurate readings and many sensor failures.
When it works it works but be aware that the sensor might randomly fail .

Transmitter and sensors are horrible!!
Y’all need to fix this immediately asap! Now I already used up all my sensors and I have none left!!
Apps issue
Apps not allowing to create account after entering all data
Terrible
I love having a CGM. But this app makes it so hard. I had to log in to share my readings with my parents, but it said “Account not found.” We tried this multiple times, with tech help on the line. We had to delete the app, and re enter everything. This is incredibly annoying as well as the “No sensor readings” and it says wait 3 hours. No. That is stupid as hell. My life is on the line because of your stupid app.

No Calibration in G6
Readings can be wildly inaccurate because the G6 cannot be calibrated. I spent 1.5 hours on the phone with your tech support, speaking to 5 people before I finally got someone who admitted to me that the G6 Pro cannot be calibrated. The sensor I am wearing now is regularly off by 20 or more points.
"Life Saver"
Dex 6 system have provided the constant monitoring that have enabled me to do a better job controlling my blood sugar levels.

Mentally draining
Sensors constantly fail just a couple days after applying, glucose is off by 100+ all the time even if you calibrate daily. I have used this app for years and it’s problem after problem. If you’re reading this you seriously need to find an alternative to Dexcom, this company is seriously awful
Sometimes I'm Scared
Why? Because sometimes the alarm doesn't sound as it should. It's especially scary when I'm low and sleeping. I don't change my phone settings so that's not the issue. When it works, it works well but it's the times I'm sleeping and it doesn't work that scare me most.
G6
App works well, support is always available and positive
Dissatisfied with sensor
My sensors always start failing in the last couple of days of usefulness. I am very disappointed with the quality of reporting, since I only get 3 for a month, which cuts me off 5 days every year. Thank goodness I can get replacement s without issue from dexcom when they do fail.
Not very accurate
I gave up on this because I kept getting woken up in the middle of the night by false low readings. It would be off by up to 100 points at times.
Fair
Seems to loose signal frequently for no reason
The adhesive also in inferior to other monitors
My insurance won’t cover other brands
