This study introduces an approach for evaluating user interfaces built on visual rhetoric and the rhetorical notion of function. A personal informatics mobile application has been selected to exemplify the application of this approach. Through the results of this example evaluation, this paper discusses the consequence of applying a rhetorical evaluation to a user interface. In this discussion, it is observed that inspecting the function performed by interface components takes into account experiences, communication, and meaning. In addition, it fosters reflection and criticism
