Great but needs some attention

Really like this system and has helped my averages come down for once in the 40 years of being type 1. 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 !

Good but could be better

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.

It’s almost there - just add a Lock Screen widget!!!

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.

Bailey,

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!

Urgent low alarm only every 30 minutes? What!?!?

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.
