Your CitySync Apps Will Power Change

Welcome to the CitySync Apps Challenge. Check out the cool stuff developers are doing with public data. You can see all the apps already submitted below.

This page is where the apps earn their reputations. This page reflects the ongoing “conversation” surrounding the best apps. Apps are ranked or promoted in terms of their display order by their overall vote ranking, their number of comments, their date of submission, and whether their source code and executable is available via an open source repository or not.
