Difficult to find the A1C data after entering the blood sugar number. Very clumsy and hard to navigate. ### 3/5 — Glucose Average *2024-08-16, version 1.1.3* Sometimes the glucose average does not agree with the 3 month lab test. Why is that ?? ### 4/5 — Great tool!! *2024-06-22, version 1.1.3* How can I download the data to excel? You should let me adjust y axis in the app. ### 3/5 — More entries per day *2024-04-01, version 1.1.3* Needs to be able to add at least 2 readings a day. Morning before breakfast and evening after dinner. ### 5/5 — Really like the app! *2024-02-10, version 1.1.3* I really like this app. My doctor loves the way the data is displayed. I would suggest that a way be added so I could put in a reading that I forgot to enter during the week. This feature could be added to the chart function. Keep up the great work! 😄 ### 5/5 — Glucose measurement app *2024-01-13, version 1.1.3* Really easy to use . Helps keep accurate data on daily sugar Monitoring.

Thanks Dave ### 5/5 — Great App I love it!!!!! *2023-11-14, version 1.1.2* I am a new diabetic and it is scary. With this app and knowing I can get a rough estimate of my A1C is exciting. I been using this app for 1 week and my A1C was 8.8%. With a lot of work and knowing I can see my A1C without going to the doctors is awesome. My A1C is now 7.3% estimated in this app. This makes you want to watch what you eat and exercise so at the end on your day you can test your blood and put it into this app and see how well you did. I am so proud of myself. This app is definitely worth it. ### 5/5 — Al Mahoney *2023-10-14, version 1.1.2* Very easy to use. ### 2/5 — Tremendous data storage *2023-10-12, version 1.1.2* I use this app every day to store and review my Glucose and A1C conversion rate.

Now they won’t give it back. If you are smart, stay away from this. ### 1/5 — Only a tracker *2025-01-01, version 1.1.3* I bought this with the idea that I could measure my A1c on my phone. This is just a tracker to record measurements that you make using other devices. ### 1/5 — A1C *2024-12-17, version 1.1.3* Not good ### 1/5 — A1C *2024-08-05, version 1.1.3* This did not check my a1c. How do I go about checking to see what my level. It’s asking me and I don’t know my level. Please advise I can’t give a higher rate because it app Did Not Help Me ### 1/5 — A1c calculater *2024-01-05, version 1.1.3* Get a chart from internet to see glucose level and corresponding A1C conversion. ### 1/5 — Decimal point *2022-10-19, version 1.0.8* Why can’t I enter a decimal point to do a reverse calculation when entering my A1C? ### 1/5 — Can’t input HBA1C *2022-09-22* Looks like a good app except you can’t use a decimal point when entering the HBA1C result as a percentage ie 5.7% It appears to load the phone keypad rather than the keyboard (no decimal point available. **Developer response:** Thank you for the kind feedback. This has been fixed in the most recent update to the application (1.1.0). ### 1/5 — A1c Calculator *2022-04-09, version 1.0.8* Still does not work correctly ### 2/5 — A lot lower than the real HbA1c *2026-06-26, version 1.1.3* I tried with average blood glucose in various settings: - of all readings - of fasting blood glucose readings - post meals readings All gave a much lower estimate A1c than the lab test. I regularly do my blood glucose 3 times a day. Very unreliable. ## Most praised reviews (10 highest-rated) ### 5/5 — Love this app *2025-12-14, version 1.1.3* So helpful in helping me track my numbers! Easy to use and very informative as to A1C comparisons and history ### 5/5 — Manual entries made easy *2025-09-28, version 1.1.3* This is the perfect glucose monitor with manual entries that’s easy to use and manually extract the A1C value in a window of time at will. I decided to manually calculate the average of two weeks and extract the A1C value afterwards. At the bottom of the A1C screen the averages are automatically calculated and the value may be entered in the A1C estimate. Very simple and easy steps, working on a screen that is unobstructed by annoying adds which cleverly run in a top bar. As a rewarding feature there’s a graphical history, too. Kudos to the author. ### 5/5 — Really helpful! *2025-09-23, version 1.1.3* It makes it easier to keep track of my blood sugar and the printouts are a nice bonus ### 5/5 — JW *2025-04-14, version 1.1.3* Use it everyday.
