This app is incredibly important to me as a diabetic, yet is impossible to use. I would give this app zero stars if I could. Some sort of major overhaul needs to be done.

Once you enter incorrect username, there is no way to enter the correct username. The app keeps using the incorrect username. The only way to log on the app is to delete the app and reinstall it. It also does not update the 90 day glucose avg correctly. My 30 day glucose has decreased quite a bit but the 90 day glucose does not change.

Good app works well but when you do a software upgrade it would be nice to have a change log of what had been fixed in terms of bugs and new features. As this is a critical medical device.

I’m trying to login to the app for my doctor and every time it says not the right information but I know it is because I am able to use the same information on the website

The Dexcom glucose monitoring app works fine but clarity is horrible. I have to install and reinstall and change the password every time I try to access clarity. I have worked with Support and with Reddit threads to troubleshoot all of the possible reason why this could be happening, including making sure my iPhone language and keyboard match my location. Very frustrating very disappointing. I don't even use it which is a pretty dismal thing when you're trying to manage your diabetes. I look at my reporting through the Tandem software. So many opportunities for improvement. This is a known issue and it does not seem that Dexcom is attending to users needs. I'd give it a zero if it was possible.

Stopped working. Uninstalled, reinstalled and still shows white screen only.

Clarity app shows no data available. Totally useless now. Response team says not working, but team is looking into it.

Every (forced update) it forgets your username/password. Fine, I'll look it up, again. Oh, oops, does not match? Well, it works with the site! Let's reset it. Ooh, oops, we dox your phone number with our password reset tool. When you enter a valid email, the next screen will show your "username" which is your phone number. Stupid.

Best I can say is that it’s adequate. The basic monitoring information is here. Detailed information that would be useful for understanding results and changing dosage or behavior isn’t included. The information is not presented in a mobile phone-friendly display. The reports are neither attractive nor user-friendly. The display is particularly frustrating. Unable to zoom and hold any particular page or graph to review - the app keeps snapping back to the top of the first page, even if you keep your fingers on the screen. Information is not available at a granular level. For example, the only two places where you can compare readings over time (say, morning fasting levels) are the overlay - which displays in a sideways orientation, so almost impossible to read; and the AGP graphs, which are tiny, can’t be zoomed and held for review, and don’t include any time or meal/activity/meds/notes data. The app seems solely and minimally designed to confirm a diagnosis and treatment plan. It does NOT provide information which would be useful for making helpful lifestyle and behavior changes; or present information in a clearly understandable or visually appealing way. There are several other CGMs with apps that present more detailed data in much more useful; more easily read and understood; and more attractive displays and reports. I recommend that any prospective user of a CGM review how the collected data is presented and the reports available in the app compared to others BEFORE filling a prescription for this particular brand.

The date in the Clarity App doesn’t change
