Description

Refracto is a user friendly tool for homebrewers that will help you to convert your refractometer measurements during a fermentation process from °Brix to °Plato and SG. It automatically compensates the alcohol effect during fermentation of your beer.


To use Refracto simply swipe to enter your original refractometer reading (from before fermentation) and the result of a current measurement. Refracto then immediately computes the following values:

- Original gravity in °Plato and SG
- Apparent final gravity in °Plato and SG
- Apparent attenuation
- Alcohol by volume

At any time you can switch between four different modes of computation:

- Standard
- Linear formula according Petr Novotný
- Quadratic formula according Petr Novotný
- Linear formula according Sean Terrill
- Cubic formula according Sean Terrill

Please note:

- In addition to this App you will also need a Refractometer with a Brix-scale.
- The supported input range for refractometer readings is 0 to 50 °Bx.

What’s New

Version 2.0

- Extended input range to 50 °Brix

- New and improved color themes
- Customizable App Icon

Well made and *_TINY_*

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.

Accurate

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.

Works great

This app works really good and I’m taking small samples with a pipette to get a gravity number with a digital refractometer I quickly do the calculation and I’m only using 5 mL of beer.
