### 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.

### 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

### 1/5 — A1C

*2025-10-17, version 1.1.3*

I would like to cancel this

### 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

### 1/5 — Don’t do it!

*2025-08-19, version 1.1.3*

I did not request to purchase this, I was just trying it out as I was told I could do and they took out $64 from my account without my permission. Now they won’t give it back. If you are smart, stay away from this.

### 5/5 — JW

*2025-04-14, version 1.1.3*

Use it everyday. Very easy to track blood sugar.

### 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
