About

Converts HbA1c levels between different units (DCCT Percentage, IFCC mmol/mol) and estimates average blood glucose levels (mmol/l, mg/dl). It uses the ADA-recommended equation and presents results to two decimal places. This tool is for informational purposes only and not a substitute for professional medical advice.

A1c

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

Trivial but exactly what I want

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. 🙂

Unusable

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

Doesn't work

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

FAQ

What is HbA1c?

HbA1c is a measure of your average blood glucose (sugar) levels over the past 2 to 3 months. It is reported as a percentage or in mmol/mol.

What is estimated average blood glucose (eAG)?

eAG is a way to express your HbA1c result in terms of average blood glucose levels, making it easier to understand in familiar units like mg/dL or mmol/L.

Does HbA1c provide medical advice?

No, HbA1c explicitly states that no information presented constitutes medical advice. It is a tool for conversion and estimation only, and not a substitute for care from a medical professional.

What equation does HbA1c use for conversion?

This application adopts the equation suggested by the American Diabetes Association (ADA) for converting between HbA1c and estimated average blood glucose levels.

What are the limitations of the values entered into HbA1c?

The app ensures percentages do not exceed 100 and negative or zero values are not input. However, it does not place other restrictions, though ranges outside 3.3%-19.1% (DCCT) or 13.7-185 mmol/mol (IFCC) are considered unrealistic.

On what devices can I use HbA1c?

HbA1c is supported on iPhone and iPod devices. It was last updated on January 8, 2016, with version 1.01.

What is the rating for HbA1c?
