  As the coffee industry has grown, there would be more demand for roasted
coffee beans, as well as increased rivalry for selling coffee and attracting
customers. As the flavor of each variety of coffee is dependent on the degree
of roasting of the coffee beans, it is vital to maintain a consistent quality
related to the degree of roasting. Each barista has their own method for
determining the degree of roasting. However, extrinsic circumstances such as
light, fatigue, and other factors may alter their judgment. As a result, the
quality of the coffee cannot be controlled. The Coffee Roast Intelligence
application is a machine learning-based study of roasted coffee bean degrees
classification produced as an Android application platform that identifies the
color of coffee beans by photographing or uploading them while roasting. This
application displays the text showing at what level the coffee beans have been
roasted, as well as informs the percent chance of class prediction to the
consumers. Users may also keep track of the result of the predictions related
to the roasting level of coffee beans.
