Signal loss - failed after warming up

The failure rate is so high it’s a waste of money

Critical Notifications

I like the app design but am super frustrated that you must enable critical alerts in order to use the app. I obviously understand where the developers are coming from but I believe it would be better to allow users the option. I personally cannot have critical alerts on due to my job, being in meetings and talking to people etc. I can’t have my phone dinging but would still like to be able to glance at my readings.

The fact I can’t read my blood sugar levels on the g7 app is ridiculous.

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.




This has helped me with my diabetes and my whole family to help me. I got diabetes October 8 and I have used my Dexcom ever since. And it has helped so much.

Don't get me wrong but this dexcom app is amazing. The one thing that confuses me though, how do you change the numbers to 70 or 101 or something. Anyway Thank you for reading . Hope this app helps. Because it helps me!!!!!!!

Oh and also if your turn your high and low alarm on and off then when you turn them on again but then you put your phone on silent mode and then turn it back off then you're alarms won't work cause I got two 2.8 and my alarm didn't even go off but I am can you do something about that.
And please can hear something about the alarm not working cause sometimes they don't work for me and then sometimes I get to 3.1 and I didn't even see it on my dexcom. And also does the same thing for my highs I go straight up to 25 even though my Dexcom didn't give me any notifications at all so please please please I'm begging you to do something about that.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!¡!!!!!!!!!!!!!!!!!!!!

Critical alerts for every alert!

Please fix the critical alerts! They should only be fore critical low glucose alerts. I do not need to be interrupted for high glucose alerts or low glucose alerts. I should be able to decide what alerts are critical besides the urgent low glucose. We already have alert fatigue as diabetics, we don’t need unnecessary alerts as well. Please fix this soon, you had this right on the dexcom g6 app, I regret that I can no longer use that app for glucose. Also fix the Apple Watch app so when I acknowledge an alert it actually lets me acknowledge or snooze the alert. Which button actually acknowledges the alert on Apple Watch? “Ok” or “dismiss”?

Huge downgrade from G6

How can connectivity be so bad for G7 when the G6 had little to no issues?

Unnecessarily Invasive

There’s no possible way to set this app up and not have it buzz, ding, and occasionally beep absurdly loud, even with do not disturb on, headphones in, and it will STILL Blair sound out for no reason. I work in an office that needs to be quiet! I can’t just turn my damn monitor off! Also beyond annoying when I’m trying to listen to music or edit videos and have it CONSTANTLY interrupted by this stupid fing notification I can’t get rid of that beeps makes sounds and pauses the music, and sometimes messes up my video edits and the sounds inside it! It’s also sometimes impossible to even select the notification that pops up and will constantly jitter around your screen as you try to click it. Overall a hot piece of a garbage app, make it so your damn notifications don’t make sound, tired of the damn stress your app causes. THERES NO NEED AND THERES AN EASY FIX MAKE A GOD DAMN QUIET MODE FFS (yes I already have mine sent to quiet mode and it doesn’t work 😒)

Better than Libre

The Dexcom seems more accurate than Libre and that’s great however, my dad cannot see the numbers. I would really appreciate settlings for visually impaired people.

Alerts can’t be turned off

There needs to be a way to turn off all alerts. Right now every high and low alert is critical and the notification silences music. There’s no reason adults shouldn’t be able to turn off their own alerts on their phones

Horrible app

Imagine an app that wakes you up in the middle of the night to tell you your iCloud backed iPhone is low on memory. Idiots.

Used to be great, now is awful

I don’t know what changes have happened in the past year but the product flat out doesn’t work anymore. Waste of money and all of my issues occur in the middle of the night. Customer service is garbage as well.

Not consistent

I’ve been Type 1 Diabetic for 10 years and have had some experience with and without technology revolving around Diabetes. I’ve been on DexCom for around 5+ years(G6 and G7). The G6 was honestly more consistent and durable in my opinion. Every sensor with the G7 is either really good or useless. When good it last a while and is always consistent. However, I’ve struggled a lot with two main problems with the G7. The main one is it completely quits on you way earlier than 10 days. I notice this happens the most when i sleep and putting pressure on my arm, since I put the sensor on my arm. It is common the device will only last 2-5 days and no way to fix it. Second problem is here and there some sensors won’t accept your calibrations. My sugar will be 130 and I get urgent warnings saying my sugar is 40-50 but won’t accept my calibrations. It’s a constant alarm.

I live the dexcom but to many inconveniences to rate it anywhere above a 3 stars.

Good app

The app is good. There is everything the sensor does come off right around eight days and you do have to keep the phone, but I like it

Absolutely ridiculous

I hate this app so much it’s ridiculous. Goes off loudly continuously especially when driving is absolutely dangerous. I cannot tolerate that it goes off for everything unrelated to glucose levels. Who monitors your app development? Are they insane? I want to throw this out of the window.

Critical Alerts Still

I guess everyone complaining about the same thing about critical alerts interrupting audio etc. for non critical events isn’t enough for Dexcom to do anything….

Still bad UX

I’m not going to focus on the sensor itself, the hardware is overall good. This app, after mode than a decade, is still pathetic.

I should be able to actually dismiss a notification without opening the app. (Why have the option if you’re not going to respect user intent.)

Figure out timers and basic math (like moving average and first derivative). Again this comes in during notifications. If the (re)notification period is 15min you should not alert me before then if I just went above threshold for a few samples.

Don’t prompt users about your stolen Dexcom sensors and force them to acknowledge every day or so. Acknowledged once is enough. I understand that your engineers don’t have to deal with this 24/7 but your users do.

Calibrations, i.e., an error signal, should be taken into account more explicitly. Again, notifications when the error rate is >100% are disruptive. I’m not 50 if 3 minutes ago I calibrated the sensor to with 140.

Notification update

They need to prolong the notification updates to be longer then what they are at the moment, to be notified that your low every 5 minutes with a high pitched noise at 3am or in public is embarrassing especially as it takes longer than that for your body to react to whatever it is you’ve ingested to help the situation, it also doesn’t help when linked with a pump and have that going off as well, I sound like an ice cream van!!

Rarely finds sensor

My phone is in perfect working order, but I went through three devices to get one to work. Such a waste of time and money.!!

Such a disappointment

I was an early adopter of the g7 and after one trial I knew it was unpolished, unready, and frankly dangerous. The app fell into the unready and unpolished categories. After waiting till I was forced to it again non of the early issues were resolved. To log in on a warning and wait 30+ seconds for that warning to pop up is embarrassing. Basic features that existed and functioned seamlessly in the g6 app to slow and cloggy here. I tried to give it a fair go but they still aren’t fixed and the app deserves the reviews it has to date. In the modern world the transmitter isn’t likely to be most people’s preferred method of information. If the app isn’t there, people will find an alternate provider.

Terrible

This app is terrible. It never finds the sensor all the while my Tandem app links with the G7 just fine. I’ve been trying this app together with the Tandem app and now for 5 sensors in a row this app doesn’t find it while the Tandem app does. The only good thing to happen is I am able to submit an error report if the G7 fails upon startup which has happened twice. I am using the proper location on the back of my arm. I don’t recommend using this app. Use the Tandem app if you have the Tandem pump.

First app I have ever used.

Can’t scroll to look at past reads like you can in Stelo. Waking my wife and I all night with alerts. We are trying to sleep. So I shut off all alerts and then the app is continuously alerting me that my alerts are shut off. I had to put my phone in the car so I wasn’t constantly woken up with alerts. First thing I did in the morning was removed the sensor from my arm and threw the 10 sensors I had in the trash. Looking for another brand.
