Whilst I do prefer the G7 over the G6; the shorter warm up period, better readings, the size of the CGM itself is great. However, one thing I noticed that is a HUGE oversight in the next generation is within the app itself. The notification volume (specifically for lows) will follow your normal phone volume for whatever reason? For example, if your phone volume is low, the notification from Dexcom will also be low. On G6, this was never a problem, it would ignore your phone’s volume, and even the silencer switch after the first notification. I was confident my G6 alarm would wake me up in the middle of the night if I dropped low. The G7 following the phone volume rather than bypassing it and being as loud as it can is an insane oversight. I have been lucky enough to hear it at low volumes, but that’s because my phone is right next to me when I sleep. However, there have been instances where I can see that my glucose was in my low range for a long time, and I just could not hear it because I fell asleep and didn’t remember to raise the volume on my phone to 100%. This needs to be fixed right away as I would rather the alarm blare out and be loud and disruptive to my workday or being in the movie theater than to pass out in my sleep because the alarm didn’t sound as loud as it should. Please fix this oversight, I may have been lucky before to hear it, but who knows if that luck will continue.

Last week I had multiple issues where my Dexcom G7 was giving me Signal Lost alerts as often as 5 minutes apart, which is the frequency the app and sensor try to connect…but I wasn’t seeing any data loss. I kept copious notes in the app Notes field and called Dexcom Customer Support. They were unfamiliar with the problem and told me to swap put the sensor for a new one and return the old one in the kit they would send with the replacement sensor. I did that, but got even MORE Signal Loss alerts than previously! So I figured it had to be the app itself. I verified with Customer Support that my data would be maintained if I skinned a new app copy over the old, and they said it was in Clarity, so I did put a new copy over the old app copy. All I lost were ALL my copious notes! The Signal Lost problem immediately went away and has not recurred, so I contacted Dexcom Tech Support and a developer called me. I told them how I fixed it and they told me to always BLOW OFF the old G7 app and download a fresh copy as they are constantly updating the app, and data (except notes) would be maintained in Clarity. They will get the solution to Customer Support and will hopefully fix the lost notes issue in the future. This app has literally SAVED MY LIFE no less than half a dozen times in the last year, so I want it fixed, not switched for another less effective solution.

The app itself is works well for me and I like the features it does have. My issues with it are the features it lacks, starting with dark mode. Why, after all these years, is there no support for dark mode?! When I wake up in the middle of the night to deal with an alert it makes it that much harder to see, process, and understand what the app is trying to tell me when I'm being blinded by the glaring brightness of this solid white screen. I already set my screen brightness at its lowest level at night and it's still not enough. I don't have this issue with the Tandem t:connect app when I need to use my pump, because they actually implemented a dark mode. My next issue is with the watch app and how few watch faces the G7 complication even supports. I just updated my watch to watchOS 11 and the photo watch face, which I had previously been using the G7 complication with just fine, no longer shows the G7 as an option. Why????? Why does there seem to be so little support for developing this app? Why does it take so long to get anything updated in this app or to add any features? If the issue isn't Dexcom and instead it's healthcare regulations that are slowing everything down, why can't Dexcom be more transparent and open about it?
