Horrible application

I never leave reviews. Came to the App Store to leave a review about how terrible the Dexcom app is. It continuously hangs, has errors, doesn’t let me dive deep into data. Can’t believe this is still an app provided to consumers in the year 2026. Next time I need a CGM I will ask my provider for a diff CGM altogether.

Does not pair w iphone

This app now sucks

It’s not the user….been using these for years. The current Dexcom and iOS 26.6 just fails to communicate.
Yes it’s in range, yes it’s in the right area, yes the app refresh is off, yes other apps are not conflicting, no the sensor probe is not bent, no it’s not into muscle (it’s roaring through the same spots as always). This combination of app and iOS is a massive fail
Fix your programming, or we just move to a competitors product….

And again …

I’m getting tired of the Omnipod 5 app failure.

I upgraded my old iPhone model 15 to the latest iPhone 18 Pro Max. The Omnipod app does not work with this new model. When I contacted Omnipod about the problem, they said yes, it’s a known problem and they’re working on it, but he had no idea when they might have a fix. What I want to know is why they didn’t get it fixed before the Pro Max 18 came out? It’s not like Apple was hiding something. Very frustrated and ready to go back to my old insulin delivery system.

Fix the app

Please make it like the G6 app where we can fully mute all notifications because i prefer it like that

Losing signal

Always have issues with no signal, no readings, inaccurate readings. Doesn’t last 10 days. Wearing Freestyle Libre and Dexcom’s G7 at same time and doing blood sticks to compare readings. Issues with Dexcom losing connection/ no readings constantly. Readings generally 30 points higher than blood strips and Libre. Plan on switching to Libre more reliable.

Display is good, overall design is poor

Very frustrating how certain parts of this app can’t be controlled. It takes over full audio function, the alarms are horrible, and no function to limit them completely. Frustrating app to deal with.

Diabetes

I love this app to use for my type one diabetes. Diabetes is one small thing in your life and diabetes is not so bad. Sure there’s a few other steps to your life but it’s not a huge deal. This app is really helpful for my sugars, and you can share it for you to the people you love. You have to they have to get a separate app so they can see your sugars, other than them looking at your phone.






Oh and also if your turn your high alarm on and off then when you turn them on again the alarm won't work cause I got two 19.6 and another time I went to 30.9. I almost went to DKA and if you want me to go to DKA then don't fix the app but if you don't want me to go into DKA, then fix the app. I know this sounds harsh but if you figure of complaint you'll get good reviews and probably get a promotion. Like a really high promotion
And then you'll get more money. If you don‘t want more money then don't fix the app. If you do want more money then fix your complaints. So get off your butt and fix your complaints please. So you'll get some good reviews. And don't tell us to go to this email or thing in the creator of response give a honest response of this response in words not us having to go to email or website.!!!!!!!!!!!!!!!




How come when you get glue and it says you can go on your dexcom app to connect with gluroo it doesn't show that you should add that that's why I give it to mine stars so three stars can you please deal with that then you'll get a five or 4 1/2

Very loud app

Only complaint is the alerts are very loud. I do not need to hear a car alarm to know that the app all of a sudden stopped working pls fix this.

Don’t work of a night

My blood sugar falls out every night and it doesn’t wake me up I wake up shaking and find my blood sugar levels at 40 and Low. So don’t depend on this to wake you up. Have a back-up plan. I hope the VA drops this company and finds one that works properly.

Brief outage more than readings

This sensor is very easy to setup and use. However despite my phone being listed as compatible I continue to get numerous daily messages that the sensor is having a brief failure and to remind me to keep my phone nearby. 98 percent of the time my phone is in my back pocket within 3 feet of the sensor. How much closer does it need to be? I have also had many sensors fail completely before the time is up. I also feel that many times it is inaccurate as it will report my reading as being in the 50’s however I do not feel that way. As I always tell people when I train them. Treat the patient not the device. Finger sticks always prove the device wring when I get readings like this.

Idk

The inconsistent alarm notifications have increased since the new iphone got released. I’m not saying its dex’s fault, but i’m sure it has something to do with apple.

Unreliable and inconsistent

For how expensive this thing is you would think the readings would be accurate. Telling me I am at 40 with double
arrows down when i am in fact in the 200s is a sure fire way to send me to the ER if I were to treat the “low” without a finger stick. The inconsistent readings and alarms that keep me up all night.. it’s just been an additional stress on top of an incredibly stressful disease that is 24/7, 365.. I cannot believe that in 2026, how much money was put into creating this device and how expensive it is for just one of them that they are this unreliable.. not to mention the strict “3 a month “ rule.. like send us extra for failed sensors!!! I’m so disappointed and sad about it all.. a bit infuriating

When dark/Night mode!?

When please? It’s so overdue. My night vision is ruined when I need to tend to an alert.

So annoying

The app is buggy. The readings are often off or ill lose readings for hours. The app is slow and sluggish and doesnt respond to my finger touches and all while screaming at me over and over and over again trying to tell me my sugars are high. I constantly set the silence all alerts for 6 hours all day long because the sound so painfully annoying and embarrassing if im out in public I have gotten to the point of almost just ripping off my dexcom in the car while driving and throwing it out the window. The alarm is SO OBNOXIOUSLY LOUD! Anyone in a 100 meter radius will know you are a diabetic. Imagine this thing going off during a college test or a buisness meeting. Give us the option to change the alert sounds. Give us the option to toggle the volume. Give us the option to disable notifications for longer than 6 hours. Fix your slow and sluggish app. And lastly the best part is that this alarm will sound off during the day at the most inconvenient times every 5 minutes but when im asleep and actually in need of a notification it doesnt make a single sound. Ill just sleep into a low and it will never let me know. I wake up sometimes in the 40s and find out ive been slowly dropping over the past 3 hours. Thats alot of chances for this piece of garbage to let me know im about to die. I hate this disease. I wish we were treated better as diabetics. I know you dont let us toggle the alarm or disable the alarm longer due to legal repercussions. But your device almost kills me once a month in my sleep. So why dont you get on that? Actually try to understand we have lives and during the day we arent just sitting around watching paint dry. We dont always want this thing to be screaming at us 24/7. There are very specific times we need it to. And specific times we dont.

Meh

Hardware is mid software is meh. Constantly having to submit units for failure and app is abysmally annoying. Now having issue of reporting failures not being transmitted.

Shut UP!

For crying out loud STOP with these alerts! Even when silenced it keeps popping up alerts to replace the sensor AS SOON AS I CLEAR IT FROM THE SCREEN! On top of that there are now 7 undeletable messages about a lot of stolen sensors that keep causing more alerts.

Update October 2026
Even with vibrate mode on this garbage app still uses the speaker loudly and incessantly when the sensor expires and also still dings loudly when a new sensor is activated. I also saw that this latest update DEACTIVATED the vibrate mode I had previously enabled permanently.

Worst app ever

Worst app ever made. It will just ring nonsense all day waking up with midnight sleep and all day this annoying ring. Instantly deleted the app. Hell no thanks

Fix notifications

This app keeps me up at night with spam critical notifications I don’t need and no way to stop it unless I delete the app. And then when I actually need to be notified it doesn’t go off half the time. Useless and dangerous.

Critical Alerts

So I guess the non critical critical alerts aren’t going anywhere. So if they aren’t going anywhere, I will. It’s ridiculous.
