Conduit allows you to create mobile apps based on RSS feeds, Twitter feeds, Facebook feeds, YouTube pages, etc,. Today Conduit added the support to create and publish apps for Windows Phone platform. This is similar to appmakr.com which already has Windows Phone support.
One of Conduitâ€™s key strengths is the way apps can be rolled out across multiple platforms such as iOS, Android and BlackBerry, as well as the mobile Web, with ease straight from the app builder itself. From today, Windows Phone 7 support is rolled out, including the ability to customize apps with the unique graphical style used by Microsoftâ€™s mobile operating system. Apps can then be uploaded straight into the Windows Phone Marketplace.
