Laggy

Why does it run so slowly. Very delayed. Not a great app wish they’d put some work optimizing it at the least

Inconsistent

Usually the alarm will go off every 5 annoying minutes on loud volume, but occasionally the alarm will be very quiet and barely noticeable. I think it’s an iphone issue because i haven’t had these many notification issues since the new iphone 18 got released.

I dont even think they listen to complaints and improve, they just comp you free products

Review of Dexcom G7

This is an extremely frustrating device

It is difficult to download. It is difficult to get the doctor to timely refill the prescriptions.

And if they were liability issues on this, they would be out of business

This is a half assed device

Privacy policy is insane!

The ability of a company to have access to personal information, and to constantly track its users, should terrify everyone!
Then to be held HOSTAGE until you have agreed to let them invade your privacy, BEFORE you can access CRITICAL BLOOD GLUCOSE READINGS.. is ATROCIOUS, and should make everyone disgusted.

That users need to send notices to multiple email addresses, and “request” to opt out of their hostage demands, should be means of government intervention on the freedoms of its citizens.

Dexcom vs Dexcom

The G7 is one of the worst apps I’ve used in my entire life (coming from someone that uses LabView). I hate the alarm sound, none of the offered “sounds” make sense or are appealing to me. It baffles me why the app takes over my phone’s audio whenever an alarm comes in. If I have my phone on silent, I’d like for it to stay silent, not BURST out every 5 minutes with a reading. What doesn’t make sense to me, is why Stelo has a better UI than the G7. If I’m paying WAY more for an app that I use every day and I have to see every single waking moment of my life, why can’t it look like Stelo’s UI? Is this some FDA, compliance problem? It makes no sense to me. Low sugar at night? Wake up the SUN in your face because whoever coded this could not add dark mode. Increíble to think this company is already thinking of a G8 sensor, when G6 & G7 are grossly unfinished…should’ve kept my small receiver…at least that has dark mode out of the box.

Sensor issues

Their sensor is very sensitive and bad quality, I have been getting issue all the time the sensor doesn’t complete it’s 10 days it stops working in 5th or 6th day!!

Alerts are annoying

It’s hard to sleep with this app going off constantly. I should be able to set quiet hours and not be disturbed

Dexcom G7

This is a complete joke ! This doesn’t work it stopped working less than 7 days ! Constantly gave wrong readings and shut down multiple times ! It’s unreliable and I refuse to use it anymore ! This will kill a diabetic !! I’m telling my doctor I refuse to use a defective unit ! It would say I’m 55 or lower and then I would test my blood sugar and it would be way higher than what your equipment showed ! You shouldn’t put out a product unless you’re positive it’s effective first !!

Please bring these back

I manage my diabetes with diet and exercise. Two things that were critical for me in the previous version are the time since the last update and being able to announce the current reading. The shortcuts app allows me to monitor the continued rise and then fall of my glucose without having to constantly check my watch. When it falls to a certain point I can stop to prevent a crash.

😡😡😡😡😡😡

Why!? I’m trying to pair a new dexcom but it won’t let me! Why? Oh i don’t know. Oh wait, MAYBE BECAUSE OF STORAGE! IVE CLEARED OUT OVER 200 HUNDRED PICTURES AND ITS STILL. NOT. WORKING

Lazy and incompetent

This has to be one of the worst devices on the market. The software is hinky, buggy, and useless. The wearables are ridiculously expensive, unreliable and fail with disturbing regularity. The notification protocols are clearly written by the company’s lawyers. There is such an opportunity here for a high quality product that provides good clinical information. Dexcom is not it.

Sensor issue

I’m getting frustrated with the constant low readings when I’m not low and the “brief sensor issue” lasted 6 hours this past weekend. Kept telling me to keep my phone within so many feet. It was literally in my hand. I wasn’t laying on it either. Which is another battle that irritates me. They recommend not laying on the Dexcom but ask to place in arm, thigh, stomach… um hello, so how do you want me to sleep—sitting up or on my back? At this point, technology should be better. I’ve tried libre and want a fan. Now I’m just to the point where I prefer not to wear this device.

Manual acknowledgement for treating lows

Please add a button to confirm that a low has been treated once I’ve eaten carbs, I don't need the app constantly alerting me while I wait for my levels to come back up. Giving users a way to mark a low as treated. The alarm is genuinely so annoying it’s making me depressed.

Unacceptable compatibility delay Critical health feature broken. IOS 27

The entire reason many of us rely on Dexcom is the ability to share our real-time numbers with our support system. Under the latest iOS (IOS 27), the sharing feature is completely broken. To make matters worse, calling support yields no answers or ETA on a solution. Leaving patients and caregivers in the dark with no timeline for a fix on essential medical software is dangerous. Dexcom, do better.

Awful Compared to the Stelo

Having tried both the Stelo and G7, I was quite literally astounded when I had to start using the G7 due to gestational diabetes because (1) the Stelo is way more accurate; (2) the food logging is absolutely abysmal (no glucose score like with the Stelo, no AI to calculate macros and calories, which arguably should be MORE important to the diabetics who need to watch carbs and sugars); and (3) the overall food logging/app experience is less user friendly. Given diabetics are Dexcom’s biggest patient base, why does it seem like Dexcom is prioritizing the product and app experience for nondiabetics over the actual diabetics? Very disappointed. Also, for gestational diabetes, they care about our glucose both 1 hour AND 2 hours after a meal, but the app only lets you pick one to track (either the 1 hour OR 2 hour).

Brief sensor issue

What the hell is wrong with the brains of the people making this garbage. I do not need an alarm every two minutes that my sensor has ended. I’m asleep. I don’t care if I’m not getting reading. Stop sending unavoidable emergency alarms to my phone you incompetent morns. I will be replacing the brand of sensors I use because of how stupidly made this app is.

Everyone at this company should be ashamed to be alive.

1 Star

I completely lost trust in Dexcom. The inaccurate readings I’ve experienced throughout 5 years of using this are not just frustrating, they are dangerous for someone with T1D whose insulin and treatment depends on accurate numbers. There have been many times where Dexcom’s readings are so inaccurate that it creates a medical crisis, whether I’m at work, home, or asleep.
A device people rely on to help prevent hypo and hyperglycemia needs an extremely high standard of reliability, one that Dexcom fails to meet. Every replacement sensor fails or has inaccurate readings, often times I don’t even receive readings. Makes me wonder why Dexcom makes so much money charging insurance, while the clients receive life threatening inaccurate readings. Diabetics deserve good technology for this disease, but unfortunately this is what we have.
I believe the FDA should closely investigate reports of significant Dexcom inaccuracies, since multiple account happen every day. Dexcom needs to get audited, these products are not helping diabetes management, they worsen it.

Why is this even still in the App Store? (Now fixed)

Earlier this month I upgraded to iOS 27 the day after its general release as I normally would and suddenly the Dexcom app stopped working properly. I called Dexcom Tech Support and they told me that the G7 app no longer worked as it required rewriting for iOS 27. When I refused their initial advice to UNINSTALL iOS 27, I was told to stop using the iPhone app and use the clunky, slow old Dexcom Receiver, which for an iPhone user is like being told to use and carry a clunky flip phone that doesn’t communicate IN ADDITION to the IPhone until they got around to rewriting the app! I’ll be seeing my endocrinologist at the end of the week and discussing alternatives with her to waiting for Dexcom to field a workable iPhone solution as I really don’t like having to carry a sick one trick pony around: I have enough stuff I really HAVE to carry! The receiver also can’t communicate with Clarity either or I haven’t figured out how to do that and am uninclined to spend more time in the past with a device one stage removed from writing Morse code to myself only.

Since I wrote the devastating review above, I felt that Dexcom having gotten their act together and apparently FIXED their product for iPhone, I owed them the courtesy of a revised review. Things are working smoothly and accurately from what I can tell, and I for one am very happy to be using this app on my iPhone again, where you can do the same thing with 2-4 taps that took more than 20 on their Receiver, and the iPhone app connects easily and seamlessly with Clarity. My endocrinologist and I are pleased.

App Suggestion

I wish they had a dark mode for the app. Going to the app to clear low blood sugar alarm, the white back ground lights up the whole bed room and wakes up my spouse.

They don’t need to know my search history as a minor

The newest terms of service is taking my data to “advertise” their product, and if you decline it then you loss access to your own Dexcom you paid that was just to monitor your glucose. So if you had stocked up on some and declined it then you loss a lot of money. They don’t need MY data to advertise their product.
