In this paper, we investigate how smartphone users navigate the dilemma of application overchoice, i.e., the scenario of having multiple competing apps available to serve a similar purpose. We analyze app installs, app usage behavior and notification attendance behavior to paint an initial picture of app overchoice and to explore how overchoice is impacted by smartphone notifications. We hope that this paper will provoke discussions and more research in the UbiTtention community on developing systems that help users navigate the dilemma of overchoice. Copyright © 2017 ACM.
