1. 5/5A very useful tool

   If you are diabetic, you need a continuous blood glucose monitoring system. I’d have a continuous blood glucose monitoring system, it should be a Dexcom g7, as it is the best on the market. If you use the Dexcom continuous blood glucose monitoring system, you must use the clarity app to collect meaningful trend data about your sugar history. It can change you life. T has changed mine. I wish I’d started using it four or five years sooner, as doing so would have prevented a heart attack — and maybe I’d still have ten toes. My a1c has gone from 13 to 6.2. I give all the credit to proper use for g ozempic, Dexcom, and the clarity app. Take care of yourself. Stay healthy. Don’t die. Someone in this world loves and needs you, I promise.

2. 3/5Need to have user defined reports and formats

   Reports are generally nice, but not quite enough for me. I’d love to see more customizable reports in formats such as *.csv files so I can download raw data to my computer to create my own charts and graphs that will be more useful for me. For example, I’d like to see how my sleep is affected by glucose activity and how my eating choices several hours earlier enters into the equation. That data isn’t shared between Apple Health and the G7 app. Same goes for other things like skin conditions that can only be tracked manually to see if/when glucose levels may be implicated. Our bodies contain dozens (hundreds or thousands?) of systems that do not work in isolation. Update: I discovered there is an export to csv function by logging into my account on the website. Sadly it’s only partially useful as the raw data doesn’t include meal text or details regarding activities. So to get the info I need, have to get glucose data here, then download custom reports to PDF, which then need to be saved as spreadsheet files, edited to remove unnecessary data and formatting, then merged with the glucose data file. Just include ALL data in the export file, please!!!!

3. 2/5Less data available in recent update

   I used to really love to review the AGP report from the Clarity app because it had detailed information regarding time in each blood glucose range. A recent update simplified the time in range information to be basically the same information on the summary. I used to see the actual percentage of time in each blood glucose range to the tenth decimal. Each .1 of a percent is 1.5 minutes! Now the AGP report removes the less than one decimal information. For example the old report would say 0.2% below 55 mg/dl now it would just show <1 for the same data. Why can’t I have more detailed information on the AGP report anymore? I love the app but liked it better when it had more of my data available to me. Hopefully this can be brought back. I already completed a support ticket right when the update came out thinking maybe the data just got moved. I learned then that the data I was looking for was removed not just moved. The change was a choice made by the developer. Per the suggestion below I put in another service request. I also removed a star because I doubt doing the same thing I did before will change anything.

4. 3/5Does the bare minimum

   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.

5. 2/5Dexcom has been Horrible

   This app is a total disgrace! After spending $500/month for these horrible sensors, the performance of this app is very poor. It will beep loud and you can only turn off alerts for a certain period of time. Lack of features. A children’s game have more reliability and rich in features then this app. The sensors randomly fail on iPhone. Good luck getting the sensor to link with Apple Watch. CVS will no replace the defective sensors and the Dexcom support gives you a very hard time to replace the defective sensors. Did I mention that the app is horrible? Over two years using this product and highly unsatisfied. I’ve seen next to no improvements in these two years, used it on iPhone 14, 15, 16, and 17 Pro Max. Ridiculous app, shame on these developers. Something is definitely wrong with the executives who lead these developers. ZERO VISION! ZERO LEADERSHIP! I DO NOT recommend DEXCOM. I wish a better company replaces their marketshare.
