1. 4/5Better experience than others

   I’ve been reading other reviews about problems that I’m (thankfully) not experiencing. The G7 is my first cgm and I’ve been using it for about 6 weeks. In that time, I’ve had it lose the connection a couple of times but otherwise it’s been solid. Far fewer problems staying connected than, say, my AirPods. Zero problems with the app crashing or sending incorrect alerts. The biggest issue I’m seeing is inconsistent readings between sensors which is obviously a problem. In terms of usability, I agree with many suggestions that others have made. The fact that I can’t click the graph to see the reading at a point in time is egregious. (It’s possible to get the number but not easy or obvious.) same goes for being limited to the last 24 hours. The Clarity functionality should be integrated and I should be informed about trends without having to piece it together myself. It’s odd that all of the logged events appear below the chart if you rotate the phone to landscape but not in portrait orientation. I get that there may not always be room to show everything, but there are plenty of established patterns for condensing markers to fit the available space. That I can only enter total carbs for a meal makes no sense. Not even a label so I know what I ate? I’ve been entering food as Notes so I have control over what gets logged. While G7 is not perfect and acknowledging that I haven’t used G6 as a point of comparison, please don’t let the reviews discourage you from getting a cgm. This one or another. It’s a complete game changer compared to doing finger sticks.

2. 1/5Useless app from overseas

   I used the G6 app during my travels, the G7 app cannot be setup from overseas, even if your residence is in the US. To start you are forced to allow access to location services ( setup screen locked until location access is granted), which in itself is an invasion of privacy. Then, contrary to the disclaimer, the location is used for comparison with the account address and the setup Is locked with an error indicating location different from residence as if one has to be locked in one’s residence. An invitation to contact technical support yields no result beside waste of communication fees from abroad ( delete and reload, create new account… ) and confusing explanations about geolocation allegedly not working in every country. It might be time for US developers to realize that the world extends beyond San Diego and Boston ! One thing is sure, on my return to the US, once my nine sensors are used up I will switch to another CGM ( FreeStyle Libre) or no CGM For US companies and software developers to be so dismissive of the rest of the world in 2024 is beyond belief! Contact suggested by Apple does not yield any result , the only suggestion by Dexcom support is to buy the receiver and basically not use / initialise the app while overseas. This is beyond belief in an allegedly global world!!! The western world view is anyone outside the west is a thief or a fraud and everything must be done to restrict or suppress his access! Pathetic!

3. 2/5Dexcom G7 app needs improvement

   The Dexcom G7 app currently lacks quite a few options and features. Here’s a list of items the Developers should work on: Add 200 mg/dL graph height option. Additionally, this could be added to the “…” above the chart for quicker customization. Add 8 hour option to Glucose trend graph. Plot blood glucose fingerpick readings on Glucose trend chart to be able to easily compare with CGM readings. Add “DarkMode” option for easier readability, especially at night. Add ability to describe or select from drop down menu the Activity; walk, run, swim, bicycle, treadmill, etc. Add ability to select from drop down menu the Meal type; breakfast, lunch, dinner, snack. Add ability to input Medication that isn’t in the search. Insulin Dose Log under Glucose tab should show up to 10 glucose readings instead of 3-4. Historical information under History tab should show more data without needing to download Clarity app. Additionally, filter options for blood glucose, insulin, medication, meal, activity, and note would be nice. Add a better way to report app bugs, provide feedback, etc. under Profile > Support > Feedback. Move Sensor information under Connections tab to Glucose tab and all the rest under Connections tab to Profile tab. Connections tab should be replaced with something more functional like medication, insulin and activity reminders.

4. 3/5Useful but frustrating

   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?

5. 1/5Cannot dismiss alerts from watch

   This app is almost good. It’s missing two features that are standard in every other app in the AppStore. And with those features it would be 4 stars. 1. Most important. Be able to dismiss alerts from the Apple Watch. I get alert, dismiss the alert of the watch, but a minute later it alerts again. Making me have to open the app on my phone to dismiss the alert. If I’m in a meeting or somewhere important I can’t be pulling out my phone or having Loud critical alerts going off every couple of minutes for something I’ve taken care of. An even better feature would be to let me get a 1 minute quiet notification on my watch that I could clear before even setting off a critical alert. But as the way it is now, I’m going to have to turn off critical alert notifications, which is not a good thing. 2. This doesn’t seem like a big one, but it is. Dark mode. It exists on Dexcom Follow app, so I know there Devs know how to do it, and they should be using shared libraries, so why am I blinding my self at night to check my Blood Sugars? A device and technology so advanced it can tell me my blood sugar every 5 minutes just by looking at a screen, when just 20 years ago we were peeing on sticks, and not long before that peeing on the ground and watching for ants. But yet my retinas burn when I check my blood sugar. And my I get just as embarrassed as everyone stares at me thinking I didn’t mute my phone for the meeting. Please fix this.
