Over the past few years, mobile applications have become an indispensable part of our daily lives. Noticing this ever- growing market, all those who are engaged in developing attractive applications should make informed decisions along the development process through sophisticated methods in order to survive in the market. As one of these methods, clustering is well suited for identifying the hidden groups existing in huge datasets. In this paper, the Mobile App dataset that contains features of 7196 available applications was clustered using two popular clustering algorithms, namely as k-means and fuzzy-c means. After conducting necessary preprocessing steps (e.g. outlier removal, standardization), these algorithms were run with different parameters in an experimental manner to reach optimal values and their performances were compared based on cluster quality (internal validity), number of iterations and elapsed time. The main findings suggested that fuzzy c- means produced higher quality clusters whereas k-means algorithm converged faster than its counterpart. In the last section, conclusions were made and future studies were discussed.
