Silence Mode

Silence mode needs to be longer than 6 hrs! It is so frustrating that I cant control critical notifications. My phone my choice. Just make me agree that Im taking a risk by silencing it for liability??

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.






Oh and also if your turn your high alarm on and off then when you turn them on again the alarm won't work cause I got two 19.6 and another time I went to 30.9. I almost went to DKA and if you want me to go to DKA then don't fix the app but if you don't want me to go into DKA, then fix the app. I know this sounds harsh but if you figure of complaint you'll get good reviews and probably get a promotion. Like a really high promotion
And then you'll get more money. If you don‘t want more money then don't fix the app. If you do want more money then fix your complaints. So get off your butt and fix your complaints please. So you'll get some good reviews. And don't tell us to go to this email or thing in the creator of response give a honest response of this response in words not us having to go to email or website.!!!!!!!!!!!!!!!

Not working again

This hasn’t been the first time and probably won’t be the last time when I try and pair my Dexcom G7 to the app it does not go through completely and just tells me to put on a new sensor but on the graph it works that doesn’t make sense and then it’s telling me to pair a new sensor. I love it when it works, but it’s just been reoccurring and it doesn’t work and I can’t get more through my insurance because of this being so common

Worst App Ever Made

Worst app ever made, there are apps with 1% of the users of this one with much less lag, glitches, and problems. Alerts constantly don’t work, screen glitches make you restart the app constantly, notifications that pop up will cause the entire app to crash.

Alerts Drive Me Crazy 😡

I don’t know what was going on in your mind when you made this but apparently it’s SOOO inaccurate, it read 252 mg/dL when it was actually 195 mg/dL 😡 and the constant ringing drives me crazy I hate having to take my dosages for Inaccurate readings
