The fidelity of mobile app prototypes affects the feedback received from participants testing the prototype. The relationship between fidelity and feedback relies on context, and it can be hard to choose the right fidelity when implementing a prototype. Exploring the differences in feedback between two prototypes of different fidelities is a step toward allowing this decision to be made in a more informed and less context dependent manner. In this study, we tested two prototypes of a multi-sided booking app: a high-fidelity fully functional mobile app developed using Flutter and an equivalent low-fidelity paper prototype presented on phone-size pieces of paper. In our between-group pilot experiment, we recruited 12 participants to carry out predefined tasks, and each group tested one of the prototypes. We collected quantitative data using the System Usability Scale survey, and we collected qualitative data using semi-structured interviews. The analysis of collected data showed that the effect of fidelity on quantitative rating of usability is minimal. However, it showed differences in the qualitative feedback between the two groups of participants. For instance, the low-fidelity groups commented on text-based content and their suggestions were about introducing new ideas to expand the current design; in contrast, the high-fidelity group commented on colour and image-based content, and their suggestions were about enhancing the current design.
