App Store 2.0: From Crowdsourced Information to Actionable Feedback in Mobile Ecosystems

Given the increasing competition in mobile-app ecosystems, improving the user experience has become a major goal for app vendors. App Store 2.0 will exploit crowdsourced information about apps, devices, and users to increase the overall quality of the delivered mobile apps. App Store 2.0 generates different kinds of actionable feedback from the crowd information. This feedback helps developers deal with potential errors that could affect their apps before publication or even when the apps are in the users' hands. The App Store 2.0 vision has been transformed into a concrete implementation for Android devices. This article is part of a special issue on Crowdsourcing for Software Engineering.
