Ratings and Reviews
Cannot access detailed data
I was very surprised to find, when I started using this app, that you can’t see a detailed view of your graph with your blood sugar level at specific intervals. As a user, I want to zoom in on the graph and see what my blood sugar level was at, at least, half hour intervals, if not 15 min intervals. The only way you can capture your specific blood sugar level at a certain time and be able to view it later is to make a note at that specific time. For a continuous blood glucose app, it makes much more sense if the app captures this historical data for you so you can go back and see what certain meals did to your levels without having to remember to check it at an hour or two hours out from a meal. If I wanted to do that, I would just use a regular blood glucose monitor at those time intervals. The graph is basically useless because it’s so small and can’t be zoomed so you can’t even tell to what level your blood sugar spiked. Very disappointed at the limitations this software provides when it could easily be so much better and more useful. Seems like an easy fix to recode this app to allow more detailed data and time intervals. Something as simple as upgrading this software could make this device go from a nice to have to a must have for tracking blood sugar levels.

Thanks for letting us know. We appreciate the feedback.
An amazing tool, but app needs work
I want to begin with my critique of the app. The critical alarm needs to be customizable. It is an ear-piercing alarm that you cannot adjust the volume of. Please allow for different volumes and allow for vibration alerts too. I understand that it’s a liability if the alarm isn’t heard, but the fact that there’s no way to lower the volume makes me uncomfortable with using it at work/in class. I can’t have this beeping when I’m attending a lecture or taking an exam. This really needs to be changed in order for diabetics to make this part of their daily life. This is my only critique as if 14 days of use. It is an amazing tool that relieves stress immensely. After 20 years of pricking my finger, it’s incredible to not constantly have to use traditional meter testing. While I still do use my meter everyday, the frequency with which I test is down by about 60%. Before Libre 3, I tested 12X a day. Now it’s around 5X. Also, the comfort of having truly accurate sensor readings upon simply opening my app is life changing. Thank you for giving diabetics some sense of normalcy and a break from the relentless guessing game of blood sugars. Even with proper management, some things just can’t be controlled. The Libre 3 has eased some anxieties and given me comfort I never thought I would have. Just please fix the alarm system. I want to enjoy this 24/7, not just when I am comfortable with a loud alarm going off in the privacy of my own home.

Thank you for your comment. Please contact our Customer Care team at 855-632-8658 so we can better assist.
Update: though I still believe the ability to see a close up of the graph is very important in increasing my low score to a 4 because I love this device and though I can’t see specific spikes like I would love to see it has been instrumental in controlling my diabetes better. I have been able to lower my A1c from 6.6 to 6.0 in the course of a few months by changing my diet significantly. I no longer feel controlled by cravings or the need to have desserts or sweet drinks and carbs.
I really believe this device should be an over the counter product for anyone struggling with diabetes, insulin resistance, food sensitivities etc. changing your diet with this diet is the key to motivation to stay on track and see results whether it’s from lowering blood sugar levels or weight loss etc.
I do appreciate this app and the libre 3 cgm, however as a newly diagnosed type 2 diabetic I am trying very hard to lower my A1C to the normal range. My numbers aren’t terrible but when something causes a spike and I miss seeing what it topped out at it would be nice to see the individual numbers. It would also be nice to see the time range between spikes and how long it takes to lower because I believe that plays a big part in your bodies ability to heal insulin resistance and metabolic disorders. Please consider making these changes in this app.
