Great CGM and App!
I enjoy using the Dexcom G7 10 CGM sensor and app. It's extremely flexible, providing three different ways to connect the sensor to various devices such as the iPhone, Apple Watch, and Remote Receiver.
I have following suggestions and feedback:
1) The Feedback button in the app is mislabeled, since tapping it only allows you to rate the app (not here in the App Store). There is no way to write a comment, such as I'm doing here. Change the button label to "Rate This App," or similar.
2) For 10-Day G7 sensors, the Direct to Watch feature in the iOS app does not work until the sensor is fully warmed up and the app is displaying readings. Therefore, the Direct to Watch button should be disabled by default and remain that way until the sensor has completed warming up.
3) I had to call Dexcom to find out how to leave feedback or suggestions. The very helpful CSR explained that feedback and suggestions should be submitted here in the App Store. In the iOS app, it would be helpful if this procedure were explained, as it would save customers lots of time.
Thank you kindly.

Dangerous and lazy
A month ago you launched a version of your app that prioritised an pushing information about your app into existing users. You know there’s a bug. You know there’s a fault. Any serious provider of a medical app that is used to monitor critical information would quickly learn from the issue and correct it. The least you could do is reinstate the old version as a temporary fix. Instead, for a month, we’ve been forced to view the same repeated message and had to manually close it to see our blood glucose levels. You’re lazy, and after weeks of no fix, it’s also clear you also don’t respect your customers.

Miss G6 Accuracy
I’ve been on the G7 for three weeks now, and I already hate it.
The sensor itself is inaccurate, even after calibrating. For example, after a hike it was telling me 227 and climbing. That didn’t make any sense after the amount of moderate activity I had just done, so before giving myself insulin i double checked with my glucometer. My actual blood sugar? 137. That’s not a small difference! That’s the difference between treating a high and creating a low.
The app also does not communicate well with the Tandem t:slim. At one point, my Dexcom app showed 181, while my Tandem app was simultaneously screaming that my CGM was reporting a low.
Which is it? I've had to do more finger sticks and manual checks with the G7 in three weeks than I did during months on the G6. That's the opposite of progress. The G7 didn't improve the experienc it severely declined. Please bring back the G6 until the G7 is actually ready.
Sincerely,
A very tired, very over it Type 1 diabetic.

Don’t install this app!!
I’ve never hated an app more in my life! It’s incredibly intrusive! When I’m working, it will let me know my blood sugar is a little low or high while I’m selling to a customer, if I don’t fix it, it then overrides the volume of my phone and maxes it out and does 2 loud sounds about 5 seconds apart! If you flick the app away, it STILL keeps alerting you loudly! On top of that, if you’re listening on Spotify and it goes off, it will completely change your playlist occasionally to another playlist! An app shouldn’t take over your phone like this. I’m done! Don’t install it!!!

Dexcom G7 15 day
In USA - not available in my country ....
calibrating
This thing is stupid. It clearly cannot calibrate correctly. It literally has a brain of a pea to calibrate correctly. I will delete if you do not fix it and I will never buy anything from Dexcom again the developers are so stupid.
Genuinely abysmal
Been using dexcom for 6 years and was forced to switch to g7 after they shut down the G6 in June/July 2026. This app is a POS. Constantly glitching out, disconnecting for hours at a time, failing sensors, the display will corrupt itself and I have to restart to fix it. I know they’re already rushing the G8 so they don’t need to fix this one, and they’re facing multiple lawsuits because of the lives this app and device have taken. Evil and shameful, and I am embarrassed that I need it to live. Lifesaving non optional software that costs half a grand a month. Blood money. 👎

Previous Days Needed
Would be nice when using the G7 to be able to scroll back to the previous days readings in the app. Other than that I love the G7 15 Day.
Amateur Broken UI
It's clear whoever coded the UI on this app skipped to foundational level understanding of user experience.
Trying to address high-level glucose alert settings when you have high blood sugar is a joke.
every adjustment you make will reset the alert settings and then trigger an alert, kicking you completely out of the settings screen all together. This will require multiple click clicks to get back into the alert settings screen, I want to get kicked out again upon your next adjustment.
The only work around for this I found was to first adjust the high blood sugar alert level to its highest setting, making my adjustments, then setting it back down (again, triggering an alert). Of course, if user forgets to fix the value after all adjustments are done, it creates a very dangerous life-threatening circumstance where you think you're being protected and you're not.
But any circumstance where UI kicks you out of a setting screen after every individual adjustment is making a third grader level development mistake.
Also, they allow you to set delays for various alerts. The UI let you select anywhere from 0 to 24 hours, and 0 to 55 minutes at five minute intervals.
The problem is the max value they allow you to select (for various timers) is 4 hours. Ironically this means of all the possible delay lengths it lets you select, well over 90% of possible choices are disallowed. Every timer from 4 hours 15 minutes up through 24 hours and 55 minutes is selectable, but it gets kicked 4 hours when you try choosing them.
This is akin to a restaurant giving you a dessert menu with 10 flavors of ice cream that they offer, only to tell you that vanilla is all they actually carry. if the flavors aren't available, don't show them to me in the first place.

New update terrible
Functionality in new update is woeful, you can’t open the app now without getting walled with tips about learn pages - highly inconvenient if you’re having a hypo having to navigate past something ‘useful’ - it would be more useful if it wasn’t there
JUNK!
Absolutely JUNK. Been a diabetic for 27 years and this by far the worst CGM to hit the market.
Terrible malware
Alerts from the app silence all other system audio. They even cause videos you’re recording with your camera to stop recording audio. I lost out on a JOB because it gave me an alert during a video interview and audition that completely shut the audio off. You should be sued for this intrusive malware. It should ding like any other notification NOT take over the entire system audio and glitch out music and videos and calls. I’ve almost wanted to uninstall it and just let diabetes take me with how obnoxious and horrible this app is.

Stop the pop up
We're sorry to see that constant learn more pop up, thanks for letting us know about this ability to learn more, but we really just want to use the app. Please fix a it as per our requests and we will get back to using the app as intended, not as coded by vibes.
Bugs
So many bugs - every time the app is launched there are popups for Dexcom support, or other notifications. Clicking dismiss just mutes till the next time the app is opened. The inbox always shows 2-3 mail items but opening the inbox shows it empty. Tried deleting and reinstalling the app and doesn’t clear. The sensor looses connection to the phone constantly and then it sends a notification every time, and that can’t be turned off, so the watch is constantly buzzing with a useless pop up. Feels like this is still beta software

LEARN MORE POPUP
Sugars low and need to check in an emergency? Let us just put a learn more pop up EVERY SINGLE TIME you open the app that you need to close. Dexcoms response to these negative reviews is comical, telling us to file a report to customer service… YOU CAUSED IT, YOU FIX IT
Poor connection compared to G6
Been using the G7 for one week now and sitting at 68% in range. I was 83-95% in range with the G6 for the past few years.
Connection to my Omnipod 5 pods is really poor compared to the G6’s connection. I always had my pods on my inner/upper arm and the G6 to the side of my belly button. No issues whatsoever for years. I tried the same, naively, a with the G7 and experienced nothing but multiple highs and ‘no connection’ via my pod handset.
A complete downgrade to the G6. Fingers crossed for a G8 soon where connection is much better!!

Absolutely terrible
have not had a single one work my entire time using it, The g6 i have not had a single problem but since i’ve switched to this i have not had a single sensor work correctly, Your better off pricking your finger don’t use this
Alerts stopping my music and other apps
Stop having critical alerts pause my music in the car! This SUCKS. I’m begging you to make it optional
Too many “learn more” pop ups
Not sure what’s happened recently but for whatever reason there is so many of these learn more pop-ups every single time I open the app I don’t care. Let me use the app for what it’s designed for.
