## Most critical reviews (9 lowest-rated)

### 1/5 — A1c

*2020-11-27, version 1.01*

Did not give me my A1c it gives other indications that I’m not interested in all I want is A1c calculated.

### 1/5 — Unusable

*2015-11-28, version 1.0*

Don't bother downloading this. It should be a simple stable app as it only involves one simple calculation. It crashes-continuously -simply unusable

### 1/5 — Doesn't work

*2015-03-27, version 1.0*

The only thing that works is the iAd... This app needs to be pulled.

### 1/5 — App not working

*2015-01-19, version 1.0*

App not working

### 1/5 — Problem

*2014-10-31, version 1.0*

This app won't allow me to enter any data . It's as if it frozen or doesn't work? I don't have a problem with any other app so it's not my phone..

### 1/5 — Poor

*2011-06-16, version 1.0*

App won't even open before it crashes so don't waste your time down loading. Shame I had to give it 1 star as can't gone it 0 or -5.

### 2/5 — needs conversion of mmol/mol

*2013-01-14, version 1.0*

The app needs a screen-picture where eAG is plotted against A1c with reference to non-diabetic range and to ADA goals. The number has no meaning if it does not have perspective where the given A1c is situated compared to normal.

### 3/5 — Almost Perfect

*2012-06-05, version 1.0*

I really like this app. It's simple to use and provides immediate results. Only thing keeping me from giving it five stars is having to re-choose my measurement parameters every time I use it. If I could choose my parameters once and set them as permanent defaults, this app would be five stars all the way.

### 5/5 — Trivial but exactly what I want

*2020-02-02, version 1.01*

Years ago I learned the formulas to convert:

eA1c=(eAG +46.7)/28.7 and
eAG=(eA1c*28.7)-46.7

I used those formulas whenever I tracked my readings in a spreadsheet. However now that I use a CGM and its reports instead of a spreadsheet for tracking, I found those reports only show glucose and not A1c. 

This app solved that by using the exact same formulas above, so I’m giving it Kudos and 5 stars. 🙂
