Dexcom ONE+

The developers have been neglecting critical bugs, such as the alert range reset, for months without releasing any hotfixes. It's incredibly frustrating to see such issues remain unresolved, especially when it directly impacts people's health. This lack of urgency is really disappointing.

Glucose levels keep restoring to default and insulin history keeps removing

Glucose alerts keep resetting to default settings

Installation problematic, they had to send me 3 new devices as the previous ones were defective. Once installed the Bluetooth sync crashed numerous times, also Apple iOS updates for new version are irregular and often not reliable. Amazing this company is authorized to operate in the medical field (including tax payers’ money NHS reimbursement) as some people’s lives rely on these reading. Dangerous, avoid !

The only possible reason to withhold essential features like critical alert is that they want more of our money on G7. It’s a simple software feature and there’s no reason they can’t turn it on for One+ with an hour of a dev’s time. They just don’t want to because they want us to upgrade and give them more money, and they’re willing to endanger us to do it. Shameful business practice.

I’ve just finished the last of my Dexcom One sensors (after 2 years of use) and have started with the Dexcom One +. The newer sensor, app and its functionality are a great improvement on the former. Thank you for your work so far. However there is one glaring omission. The option to record Insulin dosages on gives you two choices, either “fast-acting “ or “long-acting”. Please include a third of “combo” so that users of insulin mixes such as Novomix and Humulin M3 are able to accurately record their insulin type and dosage.

The app works well once the CGM has settled after the first 24 hours, but it would be really useful to be able to remove the erroneous readings you get during the first day, as these can really skew the overall average levels.

Stuck in a loop between a notice advising I need to update the app and the App Store that tells me I have the latest version. Libre was much better.

I used to love this app with it’s Apple Watch companion app and Home Screen widgets. Since the update at the start of October however, nothing has worked properly. My Watch app no longer fits properly on my Ultra screen forcing me to used the Digital Crown to scroll between viewing the current reading and the graph. The Watch also constantly fails to update with the latest readings and, after a few minutes, just shows “Check Dexcom mobile app”. My Watch complications are no longer available and the Home Screen widget now looks terrible.

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. But, what have you done to my beautiful iOS 18 Home Screen with this latest update, the widget has turned in to a square with a thick white border??? Please fix this
