Thank you! So what it really needs is constant updating! In this day and age Dexcom needs to keep up with phone updates and adding new easy to view ways. The widget on iPhone has been missing for a while now.. come on! Apple Watch reading on Lock Screen is so tiny since an Apple update ages ago.. think Dexcom and sort it for the guys with bad eyesight… I have glasses and I can’t read it hardly! We are having to use work around all the time which is silly when you have the tech and know how to sort these things! Permanent view on Lock Screen of iPhone please! It may seem insignificant to you but to us diabetics it means quick action can be taken. Let’s catch up please Dexcom and keep ahead of competitors. Both you and Apple need to stop blaming each other and put your heads together ! **Developer response:** Hi there, thanks for getting in touch and your great feedback. Our team of experts are best placed to discuss this with you. Please give us a call on 0800 031 5761 ### 3/5 — Good but could be better *2024-04-23* On the whole this is a good system, it seems to work reliably most of the time, it’s clear and easy to understand. It integrates with Apple Health and has a lot of data available (albeit on a separate app). Improvements that need to be addressed in my view are, I constantly get a message saying that Dexcom are still testing the app on my latest software version (ever since I updated to iOS 17). This should be prioritised and Dexcom should be all over software updates, both their own and iOS. It takes a longer time than I’m comfortable with to reconnect when I’m out of range of my phone for any reason. A manual check button or a force reconnect button would be helpful. I also find that I get low blood sugar soon alerts too late, for example, I may be 7.0 with rapidly falling arrows yet it doesn’t notify me until I’m almost at 4.0, it would be better to be warned more in advance, luckily I have good hypo awareness but some may find this an issue. The 2 hour warm up period is quite lengthy too at 2 hours, Freestyle Libre is just an hour which is a big difference. ### 4/5 — It’s almost there - just add a Lock Screen widget!!! *2024-03-04* I’ve had diabetes for over half my life now and Dexcom has made my life significantly better. The fact I can just look down and see my blood sugars on my apple watch rather than making myself bleed every time is 1) a massive time saver 2) stopped my hands from getting destroyed 3) has meant I don’t have to be embarrassed to check my bloods and 4) has given me better control, which is good for my health and mental health. The only thing I am genuinely surprised the devs haven’t added is a widget for the Lock Screen that displays your blood sugars- much like the one on the watch. I know it might not seem like it would save a lot of time, but especially with always-on displays all it would take would be a quick glance at your phone, rather than having to open it up. For me the speed is something I didn’t realise would be such an important benefit of Dexcom, but adding a widget could decrease that time one needs to be reminded they are diabetic massively over an extended period. ### 4/5 — Bailey, *2024-02-25* Hi, i think dexcom is great and was the best type of monitor to go for. The only problem was when i update my iPhone software i have to wait for Dexcom to update before hand, which isn't much of a problem, i hadn't known this and updated my phone to the newest version. Sadly when i did so the Dexcom app wasn't up to date with the newest version, which means it could take from 7 days to a couple months for the app to update. So the only suggestion is that they try and update the app as soon as possible! **Developer response:** Dexcom apps are classified as medical devices and we're required to test all mobile devices used with Dexcom systems. Here's a useful list of devices and apps that are currently compatible with Dexcom products https://www.dexcom.com/compatibility ### 3/5 — Urgent low alarm only every 30 minutes? What!?!? *2024-02-18* The overriding primary purpose of a CGM is to ensure the user is aware of life threatening low blood sugar levels. Instead of this, if you are having an urgent low, below 3.1 mmol/L, the app will play an alert every 30 minutes. As the user is likely to be deep asleep when they need this most, this is an incredibly stupid setting. The user could literally be falling into a low blood glucose coma and needs all the alarming and waking up they can get!!! Why isn’t this alarm continuous? Until the user is woken and responds? Why doesn’t the alarm say “Take sugar now!” Of the many failings of this app, this is the worst. ### 4/5 — Great App *2023-08-16* App does what it needs to. The customisation for the alarms is good. I absolutely love the Apple Health integration, having my blood glucose recorded there as well is extremely helpful. Really grateful that there is a companion Apple Watch app, this was a game changer for my diabetes being able to check my blood glucose at a glance any time of day on my watch Home Screen. I would really like to see some more iOS integrations like modern widgets so I can put it on my Lock Screen and on my iPhone Home Screen. It would be really helpful to see more information in the app about the Dexcom transmitter. I get one or two notifications when the battery is due to run out but these are weeks in advance and it’s very easy to loose track of when the transmitter is due to expire and if there is enough time left to start another sensor **Developer response:** Thanks for sharing your thoughts about our product, we always love to hear feedback from the Dexcom community! ### 4/5 — It’s ok, however needs improving *2023-06-13* I have recently changed from Libre 2 to the G6 - in which is amazing as it checks my levels all the time. However, I’m having issues with the alarms - they’re not going off. I’m receiving the notification but no sound, so when I’m at work my phone is on silent and at night I have the focus ‘do not disturb’. Whereas on the Libre, when my phone was on silent or do not disturb, my phone would alarm me if my sugars were high/low. Please could you look at improving this as I have noticed, on the Libre notification settings, there is an option for Critical Alerts where this will sound even on silent and in any focus setting? **Developer response:** We're sorry to hear that. Please contact our Technical Support Team who will be happy to help you resolve this issue https://dexcom-intl.custhelp.com/app/support_request/ ### 4/5 — Great, but.. *2023-06-04* It’s amazing but there are some issues. I was diagnosed with diabetes a few years ago, and was finger pricking at first. After a while of having my diabetes, I was given a Libre. It was alright, but there where some issues, so I started on the dexcom. At first it was great, no issues at all. But after a few changes, I started noticing some problems. Firstly, whenever I change the sensor, there can be signal loss for hours, even after the sensor warmup has completed. Secondly, if my phone dies, it can take awhile just for my readings to show up again, which can be quite frustrating. Overall, dexcom is great but can use some improvement. **Developer response:** We're sorry to hear that. Please contact our Technical Support Team who will be happy to help you resolve this issue https://dexcom-intl.custhelp.com/app/support_request/ ### 5/5 — Generally can’t fault it *2023-05-26* Really superb app; having been through everything else this is the best glucose monitor I have used. Love the green-ness of the fact that the transmitter is reused moving from sensor to sensor for three months. Others become expensive junk after a couple of weeks. only thing for improvement is that you can’t snooze the alarm for an hour - say - when you have a high alert and you have taken insulin and want to go to sleep. It will wake you up every 5 mins until the sugar level falls even if you have done everything you should do. **Developer response:** Thanks for sharing your thoughts about our product, we always love to hear feedback from the Dexcom community! ### 4/5 — Fantastic once bugs are fixed *2023-04-10* I’ve had Dexcom for a few years and it’s worked perfectly and helped me to keep within range at the gym and before sleep etc. being able to see the trend of my blood glucose on the graph. My issue with this app at the moment is the fact that I’ve gone through 2 transmitters in a week because the app says it is no longer working properly and to reinstall (which doesn’t fix the issue). I was wondering if this is a wider issue or isolated to myself? ## Frequently asked questions about Dexcom G6 mmol/L DXCM1 ### What is the Dexcom G6 app used for?
