Widget

I love the app. Having moved from Libre which had absolutely nothing, this is a breath of fresh air. Siri Shortcuts is a game changer within a HomePod filled home and Apple Watch support is brilliant. At first I had to tap the complication which displayed —- but with my new Watch Ultra I get the reading and arrow in the complication.

Since iOS 27 there are more issues.
As previously stated the iPhone widget doesn’t refresh and displays out of date data, rectified by going in and out of the app.
Siri Shortcuts has broken with Siri AI, even if building the shortcut from scratch in the shortcuts app. This is a major one for me, in the car I like to ask as the alarms don’t break through the driving Focus even though the app has been added.
Plus the below as added previously to my review.

What needs improving:

The manual removal of Bluetooth connection for each sensor.

The Watch complication isn’t available for every watch face, not sure why?

Needs Dark mode.

Great App but There are Issues

This App is great and shows you everything you need, however we have issues with the sensor link timing out and not reconnecting, this seems to happen when blood sugars become too low, which is slightly inconvenient. They also flash a disclaimer on the screen every time you launch, open or view the app for more than 30 seconds. Once a day or week as a reminder would be better considering it adds time when someone wants to check their blood sugar levels

IOS 27 problems - needs updating fast

Been a user for many years but Dexcom developers are so slow … IOS27 is out - it’s been in beta for months. Now under IOS27, the app is delaying every 5 minute reading by another 5 minutes before appearing in the app. When in a hypo state, this is dangerous and life-threatening. Also the hypo warning does not sound anymore with an alarm. Come on developers. Please sort this. A critical medical device should be accurate at all times and no more excuses that you haven’t tested it with your constant message when the app restarts. Your approval to IOS versioning is several versions old. It’s really bad!

Mostly good

The app is mostly good enough. On iOS 27 though it displays a warning that it hasn’t been tested, every single time you open or switch to the app. Guys I’ve seen the warning hundreds of times in the past week, please give us a way to accept / confirm / stop it.

Could improve

Would love ability to look back at individual days to compare. I can’t see the data from a particular day and display it against another.

Night mode would be helpful.

Otherwise this app works perfectly fine and has helped
me gain control of my glucose levels and drop several kilos in the process!!!!
