Attempts at building Joyride were abandoned in December 2012. Open plans gave the following reason for discontinuing the project as a Kickstarter update: "the trip planning in Joyride depends on up to date, accurate transit data, which we assemble from open data feeds provided by hundreds of individual transit operators. In the new year, the OpenTripPlanner team is spinning out from OpenPlans. With their departure, we won’t have the capacity here to keep the app up to date, and we’re not prepared to launch without being certain we can offer a viable ongoing service that people can depend on for their daily travel needs." 
The source code can still be found here: https://github.com/opentripplanner/OpenTripPlanner-iOS
Below is the previous article describing aspirations for Joyride
Beginning with Apple’s iOS 6, transit routing directions are not available within the default maps application on the iPhone, iPad, and iPod touch . However, this default Maps application will link to 3rd party applications that provide transit routing information. To enable iOS device users to continue planning transit trips, the non-profit organization OpenPlans has developed code for a transit planning app for all iOS devices. The built application, called Joyride, has not been released, but source code will be released. The application will require for a back-end routing server to be set up. The effort to create the application is currently described on the crowd-sourced funding site Kickstarter .
