Leaves a lot to be desired!! 2/5
By Burkey in SC
The app consistently looses connectivity with Dexcom hardware. My phone looses connectivity even when it is right next to their receiver and within 12-16 inches of the transmitter.
Bluetooth connection 2/5
Since I have start using the the Dexcom g6 it never stays connected with my iPhone 8+.
Unable to use app b/c of constant audible alerts 1/5
I work for a living, and cannot have constant audible alerts interrupting meetings and client phone calls. I followed the instructions to silence the alerts, but they continued anyway. I have had to uninstall the app as a result.
I cannot afford to lose my job and my health insurance as a result of this terrible flaw.
Feels very dated 2/5
I like Dexcom—I feel they are a good company. They make their data and APIs open the other developers which is something they don’t need to do, but did so anyways. The G6 is a great enhancement to my life and I am grateful to its creators for removing the need to poke my fingers.
That being said, I find the app greatly lacking in features, to be buggy, and generally not a joy to use.
Issues (ordered by largest inconvenience to smallest):
- Lately I’ve been having bugs where I’m asked to sign in, the serial number for the transmitter and sensor. This implied to me I lost the use of these devices and they were now worthless. I kept them in just in case and several hours later it somehow auto signed me in and reconnected? Biggest critique here is it feels unreliable.
- Datedness. The app is generally ugly—the colors are gross, graph is not terribly elegant, and the configuration interactions feel super dated. It feels like something a college intern put together, it worked, they shipped it, and he never came back so the app has never been redesigned.
- The alert system is terrible. I have to plug in my headphones to prevent it from beeping *despite* the phone being on silent.
Generally I feel like Dexcom is another Medtronic or Time Warner Cable—a medical company/cable provider with little market competition and incentive to improve the product, keeping us with the same set top cable box for 10+ years.
Crap App 1/5
Was on libre until insurance forced me to this unit. Trying to set up and all I get is “Can’t access the server.” So totally useless.
Always disconnects 2/5
I’ve been using the app for only about two weeks and it’s horrible. I’m constantly getting alerts that there is no signal and disconnects. I feel that it’s disconnected more than it’s connected.
Been using for only 5 days and keeps losing signal and won’t connect to Bluetooth called tech support and had me delete app and reinstall worked for 45 minutes and then nothing again seems to be useless
when phone is turned off, app logs me out 1/5
By Daniella Petty
every time my phone dies or if i have to turn it off for school the app logs me out and theni have to sign in again. then, it makes me start a new sensor! this is really affecting me in a negative way because that means i keep having to buy new sensors with money i don’t have! i’m a college student with T1D and this is really making managing my diabetes worse for me. please fix this issue!🥺
Good but Bad 2/5
I like how it is a continuous monitor but the problem is it won’t stay connected via Bluetooth. It will randomly disconnect then randomly reconnect. This has the potential to be dangerous.
Sensor Error 1/5
By great but beeds work
This topic is based off of the sensor error on your phone.
I constantly get sensor error messages whenever I exit the Dexcom app and enter another app. I simply can’t even access my news app with out it saying sensor error. The app in general is fine but this topic is horrible and you guys NEED to address this issue.
Wish I had never met Dexcom! 1/5
I wish I never had to switch to the Dexcom G6...it has taken my glucose reading 4 times in the 7 days I have had it on & the rest of the time it has had a lost signal and even though its alerted me an ungodly amount of times that it cannot alert me because it’s unable to alert me due to loss of signal. How can it alert me so many times to tell me the signal has been lost and yet I have no signal for a reading...? I regret spending my hard earned money on this product that is worthless, and I miss the Freestyle Libre, morning that was a beautiful glucose tester. Never failed & I would have never changed if not for my insurance. I want my money back! I guess I will have to go back to finger sticks, but I’ll only do it twice daily not as many times as my doctor expects of me... to painful. Also this adhesive is making me itch and I think I am allergic to it unlike the Libre. This company should not be able to sell something that doesn’t work. Sad Day!
APPLE WATCH 2/5
You should have a better setup for Apple Watch. On the older watch you had the option of Dexcom watch face. Now you have minimal choices for Dexcom and it not as good as before.
Loses connection 1/5
By Leaf 3
It loses connection too often. It will be fine one second and lose connection the next. Without a steady Bluetooth connection the app is useless. Other than that the app works great when the connection is steady and the g6 transmitter is super accurate. Please fix!
Updated to add: what is the thought process behind an alert that blasts at top volume on the first ring and then does it AGAIN when I open the app to respond to it?? I’m already responding to it?? I don’t need another top decibel alert!
I’m going to continue to complain about this app until something gets fixed. And don’t get me started on customer service for reordering...
I was unhappy with the alarms on the G5 app and they have not improved with the G6. For example, when I get a notification, the alarm or vibrate goes off and then does it again when I open the app to close the notification. It’s also cumbersome to have to dismiss a notification manually by opening the app and then clicking another button (since all other apps, opening the notification will bring you to the app and dismiss the notification). If there are two issues (like a high blood sugar and a rise rate alert) I have to open the app and then dismiss two notifications. I also periodically get a notification that the app might not work effectively with the latest IOS update, which could easily be added as an in-app message rather than another notification I have to dismiss. I understand that it’s important to have failsafe options, and I’m sure some of this is in response to FDA concerns, but this is too much! I spend a lot of time and money on Dexcom in order to keep my diabetes from running my life, but the way the alarms are set up and the amount of extra effort needed to use this app is, honestly, exhausting.
I’d also like the option to turn off the alarm volume escalation. If I don’t respond to the alarm the first time it goes off, the second time is at the highest volume available on my phone. This happens often in cases where I only dismissed one of two alarms (as mentioned above). To be frank, I hate this functionality as it is incredibly disruptive and often stressful, and desperately want to be able to turn it off.
Additionally, the graph view is very badly designed (could the text be any smaller or in a weirder place when hovering over the blood sugar reading???) and since I don’t use it frequently I’d love to be able to toggle manually between the two views rather than have it based on screen orientation. This seems like an option that could be added to the app settings so users can decide how they want to view the app. Having to try to reorient my phone every time I get a notification factors into how cumbersome this app feels to me.
I think it all boils down to options. This is an app I have to use 24 hours a day, so I really need it to work for me and my diabetes care. Being able to decide whether I want to use certain functionality would greatly improve my experience with the app. I’m sure some of this has to do with FDA regulations, but surely it would be possible to set a warning on certain settings options that by toggling the setting off, safety functionality is reduced and the user has to verify that they understand this warning?
I appreciate the peace of mind Dexcom provides me. I think with some improvements this system has the potential to be a slam-dunk aspect of my diabetes care.
Horrible crashing 1/5
I don’t know if it’s the update but my app keeps crashing and reports the app stopped working so I have to re enter transmitter and hit no code in the middle of a sensor it’s my third time this week
50/50 so far 3/5
iPhone 6 with iOS 12.4.4
App loses connection with g6 transmitter throughout the day. No evidence of loss of internet connection elsewhere so I don’t think that’s the issue.
Alarm from this app so frequently makes it impractical for daily use.
Resetting whenever iPhone battery dies 3/5
I have to put in my account info & go through all the set up steps including providing transmitter info with each app start after iPhone turns back on. Please fix this problem that started about two weeks ago.
constant signal loss 2/5
in theory this app would be great in practice, not so much constant signal loss i have to reset almost every hour. i look foward to dexcom resolving this issue
Works great when it’s actually working 3/5
It crashes constantly when follower device OS is updated. What is the point if one can’t monitor child’s condition.
Wish you had a “notes” section under the “carbs” and “exercise” events 3/5
This app is super accurate and it has made my life so much easier, however I would love to see an upgrade to the events portion, specifically the ability to add notes to the “carbs” and “exercise” events. One of the main functions of this app for me is to be able to track how certain lifestyle and meal choices effect my blood sugar levels, specifically how certain foods effect the rise and spikes of my blood sugar, and how my insulin handles specific low-glycemic and high glycemic foods. To be able to add a note of what specific type of food I ate in the carbs event would be incredibly beneficial, and in reviewing my Dexcom charts my healthcare provider and I could better determine how to better adjust my insulin regimen and eliminate or increase certain foods in my diet.
Similarly, a notes function on the “exercise” would be helpful to keep record of how certain aerobic or strength training exercises affect my blood sugar rises and drops. Being able to track over time how my blood sugar reacts to different types of exercise via a “notes” section in the exercise events would be incredibly helpful and beneficial to my awareness, knowledge and control.
Great when working 3/5
By Dylan Fan From The Dalles
I have been using the g6 with a pump for a short time, only a few months. I love it. But it fails quite a bit more than Dexcom leads us to believe. My best advice is this- Take your meter with you. Always. Do not rely on the CGM.
Battery drain on iPhone 7 4/5
The sensor and app are very convenient, though do have occasional signal loss even with the phone always close by.
My challenge is that now my phone battery drains very fast, not sure it is this app or the clarity app.
Dark mode 4/5
I love this app and the G6 but being a type1 diabetic with sensitive eyes due to diabetic retinopathy it would be nice to be able to switch to dark mode.
Needs a food log 3/5
It works great letting me know my sugar levels. It would be nice when adding a food event to be able to type in what foods were eaten so I could track what they do to my blood sugar. Right now it just lets you enter the carb counts, which 90% of the time I don’t know how many carbs are in the food I just ate.
More FEATURES PLEASE!!!! 4/5
I love Dexcom but I feel like the app should be a full diabetes management app with features that track carbs, insulin and activity better.
Connection errors. 3/5
The Bluetooth allowed me to connect to the device during set up and then after about an hour it wouldn’t connect to my Bluetooth anymore I’ve tried turning off and on Bluetooth and then waiting 10 minutes, restarting my device and then going back into the app, I’ve tried deleting the app and then redownloading it. Nothing will work.... stopped working at 2am last night and my numbers dropping the the 40’s twice. Would be great to be alerted of that. Any recommendations on how to get it to work?
Save your money 1/5
By Katie Kat 9
Constant “signal lost” message from the app. Makes me wonder what the purpose of an expensive CGM is if it only works with actual device. The Libre Sensor is much more affordable and only slightly less inconvenient. I was so excited to think I could rest easy knowing I would get an alert if my 9 year old daughter’s BG dropped. No such luck apparently...
Useless App 1/5
App never stays connected to transmitter. I’ve gotten a few hours of connection at a time but that’s about it. Tried everything recommended to fix. Gave up on it.
Unstable new version 2/5
I have been told 3 times to change my sensor after just a few days. I have been told from 2 to 4 times a day that the sensor needs to be calibrated all since the latest update. Something is very wrong with the Dexcom quality control.
Pls try harder 2/5
I’m a type 1 and I use Dexcom 96 it is a literal life saver but lately it’s been way off like one the dexcom said I was at 210 and I was at 86.
So could work on that because that is a BIG problem thx
I’m done with Dexcom and couldn’t be better 1/5
I’m done with CGM. I’ve been a T1D since 1986 and wasn’t doing bad with my blood glucose. CGM may be a blessing for some or for parents who have a T1D child or elderly parent with T2D. But the constant knowing what my blood sugar is was too much for me. Too much anxiety especially when I got numbers that I’m at 80 but I’m really at 55. I don’t mind taking my blood sugars. Dexom hardware is amazing. The software for Dexcom is poor. I will never go close looped system until the FDA requires the CGM companies to have a 90 percent or higher precision. Right now 25 percent might even be 30 percent deviation is ok. Not with me. Sorry. Been with dexcom since G5. Bye Felicia
By kilroy 22
Its junk. Doesnt work for an iphone 11
Great but not enough for T2D 3/5
This is a well written app. It’s fairly stable, has Apple Watch and Siri integration. Great alarms setup.
However, since the CGM product is now being pushed to T2D patients. It’s missing the T2D medications in the events. Most people use Metformin plus other prescriptions. I’m surprised that it’s not been updated with that feature. I’m resorting to putting it in as Insulin at 0.1 U to show when my prescriptions are taken. This is probably confusing on their part as I'm T2D and don’t take insulin. They should also offer different carb types or GI index foods.
Please add these feature soon.
Not worth it anymore 2/5
Never have I had this much trouble out of my Dexcom. It is constantly losing signal. The lows and highs are wrong and if I try to calibrate. It loses signal. I’ve had the updated version, turned off and on Bluetooth and restarted my phone. Even reinstalled the app. Nothing makes it connect.
The g5 never gave me this many issues. It’s not worth the money I have to pay for the supplies.
They're deleting my post 1/5
By Rip off one
I tried putting a link for FDA complains but they keep deleting my post . So put in your Internet browser online. Medwatch voluntary reporting form click the link and follow directions. very odd how they delete the actual web address i posted. Look you cant have a diabetic medical device that tells you your bood glucose is 86 when its really 43 the more complaints the better the outcome for a more reliable medical product. The G6 should not have been approved for dosing decisions with a 30% waver in readings from your BG meter or hole blood glucose from a blood draw Laboratory.
Works for a few hours then nothing 1/5
By Pam B 1980
This is a great concept. When it works, its great. Ive been using the Dexcom for a month now and the product itself is great—the App, not so much. Never seems to link up longer than a few hours and my family really wants to be able to see my numbers. I have an iphone 8. Family has androids
Garbage reliability 2/5
Great when it works, but is very often not working. The App stops working at inopportune times, which is ultimately pretty dangerous.
Can’t dismiss notifications on watch 3/5
By Justin t1d
G6 works well for me however whenever I get a notification (low, high, trending, etc) I’ll dismiss it on my watch, but then ALSO have to unlock phone, open app, and dismiss notification there too. If I don’t, notification turns into alarm, which it should if I don’t dismiss, but I dismissed it! Basically dismissing on watch should dismiss. I’m already responding to alarm and trying to treat, having to jump through hoops on my phone is annoying.
No need for customer service when you don’t have a choice. 1/5
By organic beast
Worst customer service ever. Where supposed to call back “within 48 hours” of a specific time. Well 120 hours later and well before said set time I get a call back. I missed the call because I was working (the whole reason I set a specific time at their request) and then get stuck on hold for 45 minutes before being hung up on. If you have a choice through your insurance DONT use this CGM
Regularly loses signal 2/5
Unreliable for capturing and sharing data, alerting for lows. Crashes often and alerts for signal loss when the device is inches from the transmitter. Really annoying in the middle of the night.... still have to carry the receiver because I can’t rely on the app. Too bad because this functionality is a huge selling point for Dexcom... crash and burn too often...
TRANSMITTER LOSES SIGNAL FREQUENTLY 2/5
By Unsafe with Updates
Dexcom updated something and this app and it pairs only intermittently with the transmitter
It’s not bad, but please remove notice 3/5
The app works fine, although i wish there was a minute counter to see how long I have until the next reading (like on the follow app). I also wish you would remove that stupid notice where I have to hit “continue to app” every time I try to see my number. It gets annoying and my phone lags as it is. Sometimes I push the online website button instead which is annoying, so just give me an option to never see that notice again please. Other than that, the app works great and is really helpful.
Keeps logging out 2/5
By Boss lady Target
Wake up to my app asking for my username and password only to find I have to go through entire set up again and then replace my sensor. Very disappointed
Good.. when it actually works 1/5
My phone died so I was prompted to log back into my account for some reason, I do and the app has reset ALL of my data and information, and I’m on my last sensor as well. Thanks for wasting my time and money you terrible app
Loses signal 1/5
By ones 23
Loses signal proly 20 times a day every time you update your phone. What a joke. Then support contacts you and says let’s talk. How about you read all the reviews that say the same thing. Dexcom G5 never had this issue
The app says it will work but the moment I hit let’s start it says the app is down. This is after trying it for three days.
CONSTANTLY loses signal with phone and receiver. Approximately 15-20x per day I look at my phone and it says lost signal. I’ve tried looking up every type of “fix” I can find and nothing works. I’ve deleted and redownloaded the app 4 different times, reset network settings on my phone, shut Bluetooth off and on, phone off and on...nothing works. I’ve called customer service but the person I spoke to said I needed to call tech support and I left a message and did not get a return call. I thought maybe it was a bad sensor so waited til it was time to place a new one...now, four sensors later I’m Still having the same issue. My whole reason for getting the Dexcom was to have a device that would feed to my husbands phone as well. But I can’t even get it to feed to the receiver or my phone! Sometimes I go in and click ok when it tells me that the signal was lost and that it could take 30 min to reconnect, and two hours later I still can’t get it to connect. Very disappointed in it. Will be talking to my doctor about a different device.
Ios13 and iPhone 11 do not work with this version 3/5
Just all dropped signals, on my tandem and the app. Once I removed the app the tandem worked normally. My chess game has updated three times for ios13......
Still loses signal and causes the tandem to also lose signal with latest update for app and iOS iPhone 11 pro Mac. 😞
The last iOS update fixed this issue for me.
Can we get a check box that let’s us skip the perpetual os warning screen and go right to the main screen?
Great Idea, Poor Implementation 1/5
An update. While I continue to use my G6 - Dexcom has failed to update the app to support the iPhone 11. Which means both my Watch 4 and my iPhone 11 no longer work for the past ; months. They can give no reason why and no estimates of support. I have fallen back to using their receiver / which is short range (barely 10’), short battery life and inconvenient to carry. This is incompetent and arrogant. Why is this so hard???
As a new Type 2 diabetic the G6 promised two things that were important to me - no more finger sticks (currently doing 4/day) and more detail about how diet and exercise affect my glucose and this health.
Sadly, after about 22 days on the system, Dexcom not only has failed to deliver on both expectations but created a third issue. They don’t answer Tech Support emails and their Tech Support phone seems eternally busy. Makes Comcast tech support look positively wonderful.
The sensors seem incredibly inaccurate compared finger stick meters - up to 50% error - and hence untrustworthy. Their promise of no calibration is false - and further G6 performance does not seem to improve with the calibration data from parallel fingersticks. So - I continue using fingersticks in parallel to the G6. There IS much more information but sadly untrustworthy. Being woken continuously in middle of night with false positive glucose highs or lows is just truly truly annoying. Did I mention these alarms cannot be disabled? If the sensor worked, this would be a feature.
The inaccurate performance and lack of responsiveness is so appalling that I now have to resort to comments on the App Store short of calling CEO and FDA.
Sadly. A great idea. Incompetently executed. Uncaringly supported.
