Signal loss - failed after warming up

The failure rate is so high it’s a waste of money

Critical Notifications

I like the app design but am super frustrated that you must enable critical alerts in order to use the app. I obviously understand where the developers are coming from but I believe it would be better to allow users the option. I personally cannot have critical alerts on due to my job, being in meetings and talking to people etc. I can’t have my phone dinging but would still like to be able to glance at my readings.

The fact I can’t read my blood sugar levels on the g7 app is ridiculous.

Diabetes

I love this app to use for my type one diabetes. Diabetes is one small thing in your life and diabetes is not so bad. Sure there’s a few other steps to your life but it’s not a huge deal. This app is really helpful for my sugars, and you can share it for you to the people you love. You have to they have to get a separate app so they can see your sugars, other than them looking at your phone.




This has helped me with my diabetes and my whole family to help me. I got diabetes October 8 and I have used my Dexcom ever since. And it has helped so much.

Don't get me wrong but this dexcom app is amazing. The one thing that confuses me though, how do you change the numbers to 70 or 101 or something. Anyway Thank you for reading . Hope this app helps. Because it helps me!!!!!!!

Oh and also if your turn your high and low alarm on and off then when you turn them on again but then you put your phone on silent mode and then turn it back off then you're alarms won't work cause I got two 2.8 and my alarm didn't even go off but I am can you do something about that.
And please can hear something about the alarm not working cause sometimes they don't work for me and then sometimes I get to 3.1 and I didn't even see it on my dexcom. And also does the same thing for my highs I go straight up to 25 even though my Dexcom didn't give me any notifications at all so please please please I'm begging you to do something about that.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!¡!!!!!!!!!!!!!!!!!!!!

Critical alerts for every alert!

Please fix the critical alerts! They should only be fore critical low glucose alerts. I do not need to be interrupted for high glucose alerts or low glucose alerts. I should be able to decide what alerts are critical besides the urgent low glucose. We already have alert fatigue as diabetics, we don’t need unnecessary alerts as well. Please fix this soon, you had this right on the dexcom g6 app, I regret that I can no longer use that app for glucose. Also fix the Apple Watch app so when I acknowledge an alert it actually lets me acknowledge or snooze the alert. Which button actually acknowledges the alert on Apple Watch? “Ok” or “dismiss”?
