Nowadays, it is important to design and develop effective applications for improving solution experiences in the fields associated with studies of biomedical and health informatics. Along with rapid developments in computer and electronics technologies, that has become more important in especially twenty-first century. Moving from that, main objective of this study is to deal with the problem of heart sound analysis and disease diagnosis by using a mobile application that can perform the mentioned tasks by having also support from both virtual reality- and augmented reality-oriented components. Thanks to the using features and functions provided over the application, it is possible to analyze signals instantly and have rapid feedback over the interface supported with virtual or mixed reality objects as combining both real and virtual worlds in a common ground. The paper briefly focuses on technical background and essentials of the developed mobile system and then evaluates its performance in the context of different perspectives.
