Pros and cons

This app is a game changer and I understand that however there are a few things (this may just be on my end but still.) I am getting signed out and having app errors at least twice a month if not more (more often then not more), which means I have to delete the app redownload the app, and do all of the onboarding sign on things. Really tedious and super annoying, but this happens very often. Another thing I also seem to be having issues with it the connection through me devices. Sometimes it will be working really well, and then all of the sudden I won’t get readings for my numbers for hours or even days. Which is really upsetting, especially if this happens when I’m out and I don’t have access to my meter. Another issues is receiving notifications, and I’ve gone in and checked, and redone them several times now to try and get them to do what I set them to be. I’m not sure about you guys but when I’m low i get to be especially Cranky, and hearing the beep every 5 minutes absolutely ticks me off. The beeping I understand is necessary however if I’ve taken action I don’t see the need for it to go off every five minutes. This being said I’m not sure why my notifications setting aren’t being activated, or used. A lot of the other issues I’ve had in the past aren’t really problems anymore besides the connection issues. This app overall has helped me a lot, and it’s been very good to keep and constant track of my blood glucose lvls.

Good but could be better

Love what this app does for me. A few suggestions that most people have listed. Night mode - The white background when I check my sugar in the middle of the night, brutal. Complications on the Apple Watch should have versions for small and large complications. As they are now, with my aging eyes, I can barely see them. More health app integration - My doctor doesn’t have access to my health data but does have access to my Dexcom data. The Dexcom/Clarity app should be able to read more health data like exercise for example so they can see how exercise effects my blood sugar. It should be automatic by accessing the health app date, I shouldn’t have to manually input exercise. When I do input exercise, it defaults to start time when I enter and only calculates in minutes. So I have to do math to figure it out. Alerts - My high blood sugar alert is set to alert me every 15 minutes but seems to go off every 5 minutes. Please fix. Fix these and I will give 5 stars. Thanks.

Edited for another request: Please add support for a Lock Screen widget. Not the screen where I swipe right from the Lock Screen but on the actual Lock Screen. My request above for a bigger watch face complication aside, legibility on my phone would be much better and I wouldn’t even have to unlock my phone. I don’t care if someone knows my blood sugar reading, so privacy is not an issue. Please consider. Thanks.

Works great + great support. Needs updated watch complications.

Downloaded the app after getting an Apple Watch - love it. Haven’t had any issues with signal loss myself (iPhone X, almost always near me). I am using the watch complication with the older Apple Watxh face (Modular), but like everyone else here would love to see an update supporting some of the newer Apple Watch faces (e.g. Infograph Modular). Sometimes the numbers don’t update on my complication (I see “- - -“) but this is an Apple Watch issue, not Dexcom. Tapping it opens the Dexcom app and fixes the issue. Keep the Dexcom Apple Watch app running in the dock, and keep the Dexcom app on the phone running in the background to minimize this from happening.

But the most impressive for me was Dexcom support. I contacted the email address Dexcom keeps posting in replies to other reviews, and got a personal call back on my phone from a knowledgeable tech support rep. I thought my Dexcom app was ignoring my high alert repeat settings - but turns out dismissing high alerts on the watch is not the same as dismissing them in the Dexcom iPhone app. I now dismiss alerts in the Dexcom phone app and my alert repeat settings are honored. Again - was an Apple issue, not a Dexcom app issue.

Thanks Dexcom for innovating! While the app can always be improved - you all push the boundaries more than other CGMS providers when it comes to innovating within the constraints of the FDA approval process.
