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.
