The GINA brewing app is an integral part of the GINA Smart Coffee brewer. The app connects to the integrated scale in your GINA brewer and enables you to track the weight and time, which are core tools for brewing a great cup of pour over or immersion coffee. The app helps you determine the perfect coffee to water ratio with the useful ratio calculator. With seamless Bluetooth connection and epic scale accuracy and a hands free start of your brew timer, this app will level up your coffee brewing.
