Refracto

This app is very easy to use. My only problem with the app is it will not calculate FG below 1.000 for my wines and meads.

I have been using this on several batches of home brew & comparing with hydrometer readings. It is very close to my hydrometer & use a lot less brew to get your ABV. I’m surprised at how well it has compared. I have tried other apps like this that were way off & unless.

At 569 Kbytes, this is a purpose built tool for brewers of all stripes. It also supports multiple algorithms for conversion and the scale values are persistent from one execution to the next (which is GREAT if you are tracking a fermentation). Simple to use and easy to calibrate if you have both a Hydrometer and a Refractometer to plug in the correction factor. The dual theme GUI (light and dark) is a plus as well. Kudos
