## What is Dexcom G6?

Only use this app if you have the Dexcom G6 or G6 Pro CGM Systems.


Always know your glucose number and where it’s heading with the Dexcom G6 and G6 Pro Continuous Glucose Monitoring (CGM) Systems –indicated for diabetes treatment decisions with zero fingersticks and no calibration.* Before you start making treatment decisions with your G6 or G6 Pro, work with your healthcare provider to learn how.


*Fingersticks required for diabetes management decisions if symptoms do not match readings.


Always know your glucose number with just a quick glance at your compatible smartphone or smartwatch.  For a list of compatible devices visit www.dexcom.com/compatibility.  Dexcom G6 and G6 Pro provide real-time glucose readings for patients with type 1 or type 2 diabetes every five minutes. Dexcom G6 and G6 Pro are indicated for children, age 2 years and older.


The Dexcom G6 and G6 Pro Systems provide personalized trend alerts on your smart device and let you see when your glucose levels are going too low, or too high, so you can better manage your diabetes. The Alert Schedule** feature lets you schedule and customize a second set of alerts.  Custom alert sounds are available, including a Vibrate-Only option on the phone for glucose alerts. The only exception is the Urgent Low Alarm, which you can’t turn off.



The Always Sound** setting, which is on by default, allows you to receive certain Dexcom CGM Alerts even if your phone sound is off, set to vibrate, or in Do Not Disturb mode. This allows you to silence calls or texts but still receive audible CGM Alarm and Alerts, including the Urgent Low Alarm, Low and High Glucose alerts, Urgent Low Soon Alert**, and Rise and Fall Rate alerts**.  A Home screen icon shows you if your Alerts will sound or not.  For safety, the Urgent Low Alarm and three alerts can’t be silenced: Transmitter Failed, Sensor Failed, and App Stopped.

• Share** your glucose data with up to ten followers in real time. Followers can monitor your glucose data and trends in real time on their compatible smart device with the Dexcom Follow** app. Share and Follow functions require an internet connection

### 1/5 — DONT UPDATE THE JUNE/JULY 2026

*2026-08-03, version 1.16.0*

Don’t update the June/july 2026 update they don’t care about how laggy the app is now that the G6 is retired

### 1/5 — The app disappeared from my Apple Watch

*2026-07-26, version 1.16.0*

The app on my Watch disappeared, and I have no reason why. Still works on my phone, but I rely on it to work on my watch as well.

### 5/5 — G6 ending?

*2026-07-25, version 1.16.0*

-Update-
Based on the automated response below, I think it’s safe to assume that this update will do nothing except remind you every 20 minutes that the G6 is being phased out, therefore it’s best not to do this update unless you want to be annoyed. Continue to use your remaining G6 patches in peace.

— If the only purpose in this update is to let us know that the G6 is being phased out please tell us that! It’s not worth updating if that’s the only difference

### 1/5 — I love Dexcom but..

*2026-07-25, version 1.16.0*

The graph has disappeared since yesterday’s update.

### 4/5 — Discontinued but served me well through its lifespan

*2026-07-15, version 1.15.0*

Sad that these got discontinued, it was a huge breakthrough in diabetes management technology and had a good experience from 2018 to 2026.

### 5/5 — R.I.P G6

*2026-07-10, version 1.15.0*

Dexcom canceled G6 if you have some still you can use it or you switch to G7. R.I.P G6

### 1/5 — Years-long bugs and unreliable alerts

*2026-06-29, version 1.15.0*

I’m wearing my last G6 sensor before I switch to the G7, but figured now is as good of a time as any to leave a disappointed review of the app.
On the positive side, I am grateful that this technology exists, and that when the sensors fail (as they do about once a month on average), the company is usually accommodating with free replacements. Dexcom Clarity is also a highly useful element of this product, but this review pertains only to this app. 
Unfortunately, the alerts, which are the most crucial features of the app, are somehow both unhelpful and startling at the same time. I wish there were a way for me to acknowledge high or low alert early if I know I’m going to get one in a few minutes anyway. There’s really nothing like knowing my blood sugar might go out of range and wanting to silence that notification early, but having countless interviews, classes, etc., interrupted by a noise that disrupts everyone around me in a 50 foot radius. Not to mention how, although I have rise and fall rate alerts turned on, they only notify me after my blood sugar is out of range when the rise or fall rate was already significant almost an hour before the app made me aware of it. 
The integration with iOS is also disappointing, because Siri has extreme limits on what information she can share with me, and the widgets rarely have real time data. The warm-up time being two hours long is extremely inconvenient for people who rely on this technology so much. My sensor will end at 110, but the next one will begin at 254 as much as I try to prevent it.
It’s also concerning that when there may be an issue with the sensor, the app is extremely generous on guessing the glucose values, often insisting that my blood sugar is up to 200 or 300 points above or below my actual glucose reading.
Lastly, my app has had a bug for about five years now, that no iOS, app version, or iPhone model upgrade has been able to resolve. When launching the app, the orientation of the graph sometimes flickers from horizontal to vertical back-and-forth several times, and usually lands in an orientation that glitches so badly that most of the indicators and buttons are invisible. This happened about once every day or so for the last five years, and requires me to quit and reopen the app in hopes that the glitch resolves. Nobody on tech support knew how to resolve it. 
The graphics used to illustrate the sensor in the app are poor and could have easily been improved by a few hours redrawing them in a vector program. 
Even the features like “add event” are not intuitive, and I didn’t feel inclined to use them at all in the last 10 years.
When looking at the color scheme, feature placements, fonts, and symbols, this app has never looked better than something a design intern could have whipped up in Figma with one day of training. It’s truly abysmal for a company that is so uniquely positioned in the market, is trusted for critical medical information by so many people, and charges hundreds or thousands of dollars for their products every month. I look forward to switching to the G7 soon, but I am desperate for a completely different experience than what I had with the G6.

### 2/5 — Unreliable

*2026-06-13, version 1.15.0*

Unfortunately after 3 years of use this has been more of a challenge then a help with managing my blood glucose. 

After calibration it will have its periods of inaccurate readings and many sensor failures. 

When it works it works but be aware that the sensor might randomly fail .

### 1/5 — Transmitter and sensors are horrible!!

*2026-06-10, version 1.15.0*

Y’all need to fix this immediately asap! Now I already used up all my sensors and I have none left!!

### 2/5 — Apps issue

*2026-06-07, version 1.15.0*

Apps not allowing to create account after entering all data
