Dexcom ONE+

Unlike your other reviewers (moaners), I find this app helpful and easy to use! The alerts are easy to set up and the sensor is so accurate that I switched to it from the Libre 2. Thank you for making an awesome app that helps me manage my Diabetes better, oh and I love seeing my Insulin trends, that was one feature Libre didn’t have and is very useful.

lock in why u not give me alert even when on silent so dum bum

It’s hard to understand how a company who makes the sound Dexcom G7 suite of apps which are almost identical to this can make a product so poor. The iOS widget hardly ever updates. The Apple Watch app almost never updates and the Apple Watch widget hasn’t worked once.

As a user coming from the G7 to the One+. The app feels super underdeveloped and unfinished in comparison to the G7. There are no Alerts for Rising and Dropping glucose levels, Broken Apple Watch support, No glucose Range customisation, and worst NO CRITICAL ALERTS. So you need to ensure any focus modes are set to allow the app to break through, never have your phone on silent and pray your notification volume is loud enough to wake you at night. Overall the app feels rushed and missing some key features. You’re better off going with an Abbot Libre 2 for cheaper and with better notifications for lows and highs.

The Dexcom One+ app is a major disappointment, earning just one star from me due to its lack of essential features. You can't switch between mmol/L and mg/dL for blood sugar readings because the units are fixed based on your location. There's no flexibility in setting your blood sugar target range, with just one option available. Similarly, adjusting the graph height offers no customization, limiting you to two preset options. The Apple Watch integration is broken, displaying an error message to check the mobile app, and there's no Dark Mode available for easier viewing in low light. This app desperately needs improvements to meet basic user expectations.

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.
