Works great. Hate the alarms

Look. I love this app. Love the graphs. The alerts are good too for a heads up on what’s going on. But my GOD the alarms!! Over the top ridiculous. When you’re low or high and hit your limits the volume of the alarms, especially if wearing headphones, is insane. I’ve almost driven off the road multiple times , dropped weights, and literally pulled the headphones outta my ears on runs due to the volume of these alarms. They need to be adjustable or incrementally get louder but these alarms will absolutely deafen a brotha. These alarms alone make me wanna not use them at all. I don’t know why this hasn’t been addressed. Due to this I almost always silence the alarms but then what’s the point of having the Dexcom on? Please fix this. Also with the new update of the calibration alarms it’s like, my god!! Another alarm I can’t adjust?! I’m not always able to calibrate when it wants. Can’t silence them or adjust these alarms. So every 5 minutes I get an alarm for something that absolutely is NOT an emergency. This alarm needs adjustment features too. This is a simple app that doesn’t need a lot of features. Could be great but this is why it has the rating is has. It’s well earned. Bottom line… Dexcom is life changing technology. The app has a lot of catching up to do. Please fix this Dexcom

Good, but…

I’m a tween living with type 1 diabetes, and honestly this cgm is good, but needs just a few improvements. I like that it reads my blood sugar every 5 minutes and predicts urgent lows. However, I wish that it would predict regular lows and highs, because my tslim insulin pump connects to this cgm, and it can do that. I also love that it sends alerts to my Apple Watch from my phone and that, like I said earlier I am in LOVE with the fact that it connects to my insulin pump so that it’s much easier to manage my diabetes. It’s also great that you can get free overpatches, which are especially great for the pool, so that the cgm doesn’t come off as often. Usually though, the adhesive is pretty good, and I don’t even need the overpatches. I also really love that you can customize the sounds of the alerts, it’s nice.I know that the Dexcom clarity app has night mode, and I really wish that this app had that too, because honestly, no one wants to wake up to an alert at 3am and then see a screen bright as the sun. I also think it would be great if maybe the sensor warmup didn’t take so long, if possible. And finally, my most important complaint. We all know diabetes is really hard, and putting on this sensor SERIOUSLY hurts. So please, if you can, make it less painful. Thanks, you guys are doing a great job, and I really don’t want to seem whiny or like some idiot Karen. Really, your cgm is pretty awesome.

Works great + great support. Needs updated watch complications.

Downloaded the app after getting an Apple Watch - love it. Haven’t had any issues with signal loss myself (iPhone X, almost always near me). I am using the watch complication with the older Apple Watxh face (Modular), but like everyone else here would love to see an update supporting some of the newer Apple Watch faces (e.g. Infograph Modular). Sometimes the numbers don’t update on my complication (I see “- - -“) but this is an Apple Watch issue, not Dexcom. Tapping it opens the Dexcom app and fixes the issue. Keep the Dexcom Apple Watch app running in the dock, and keep the Dexcom app on the phone running in the background to minimize this from happening.

But the most impressive for me was Dexcom support. I contacted the email address Dexcom keeps posting in replies to other reviews, and got a personal call back on my phone from a knowledgeable tech support rep. I thought my Dexcom app was ignoring my high alert repeat settings - but turns out dismissing high alerts on the watch is not the same as dismissing them in the Dexcom iPhone app. I now dismiss alerts in the Dexcom phone app and my alert repeat settings are honored. Again - was an Apple issue, not a Dexcom app issue.

Thanks Dexcom for innovating! While the app can always be improved - you all push the boundaries more than other CGMS providers when it comes to innovating within the constraints of the FDA approval process.
