Dexcom G6

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.

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 .
