Why is this even still in the App Store? (Now fixed)

Earlier this month I upgraded to iOS 27 the day after its general release as I normally would and suddenly the Dexcom app stopped working properly. I called Dexcom Tech Support and they told me that the G7 app no longer worked as it required rewriting for iOS 27. When I refused their initial advice to UNINSTALL iOS 27, I was told to stop using the iPhone app and use the clunky, slow old Dexcom Receiver, which for an iPhone user is like being told to use and carry a clunky flip phone that doesn’t communicate IN ADDITION to the IPhone until they got around to rewriting the app! I’ll be seeing my endocrinologist at the end of the week and discussing alternatives with her to waiting for Dexcom to field a workable iPhone solution as I really don’t like having to carry a sick one trick pony around: I have enough stuff I really HAVE to carry! The receiver also can’t communicate with Clarity either or I haven’t figured out how to do that and am uninclined to spend more time in the past with a device one stage removed from writing Morse code to myself only.

Since I wrote the devastating review above, I felt that Dexcom having gotten their act together and apparently FIXED their product for iPhone, I owed them the courtesy of a revised review. Things are working smoothly and accurately from what I can tell, and I for one am very happy to be using this app on my iPhone again, where you can do the same thing with 2-4 taps that took more than 20 on their Receiver, and the iPhone app connects easily and seamlessly with Clarity. My endocrinologist and I are pleased.

App Suggestion

I wish they had a dark mode for the app. Going to the app to clear low blood sugar alarm, the white back ground lights up the whole bed room and wakes up my spouse.

They don’t need to know my search history as a minor

The newest terms of service is taking my data to “advertise” their product, and if you decline it then you loss access to your own Dexcom you paid that was just to monitor your glucose. So if you had stocked up on some and declined it then you loss a lot of money. They don’t need MY data to advertise their product.

Greedy Profiteer

If I could give Dexcom 0 stars I would. We are patients not customers. Incredibly poor quality device.

Great monitor, shockingly bad app

As a diabetic and professional software designer I am shocked at how badly this app is built. Endless annoying unnecessary alerts, lack of historical data at your fingertips, clumsy UI and so on. This could easily be solved by listening to your customers here, but every reviewer gets a trite response that is never followed up (just see).
