You should check out the site when its back up, obviously the app auto updates when new content is published.

It works because you have to install a plugin in your WP blog, which presumably has WP publish/edit hooks etc which notifies an Appifier service, which then pushes to the apps, making sure all content is up to date and available offline. It's a pretty popular, if not the only, design for content surfacing apps.

It is actually not obvious. Now the site is back up I can't find anything that explains how updates are handled, or how offline works. For all I can tell the plugin might just be to build the app... I hope you are right as that is more useful. Some explanation would be good...
