The aim of this App is to improve your brewed coffee by using an affordable analog Brix refractometer and a hygrometer, like the ones shown above. Studies have found a close relationship between Brix and TDS, so this App can be used to convert Brix measurements to TDS (Total Dissolved Solids).

This App accurately converts Brix to TDS, and also computes the extraction yield. You can measure a brewed coffee and also plan a brewed one.

Some of the equations implemented in this app are described in my work entitled: Converting Brix to TDS - An Independent Study, available at:
