This plugin provides JSON data to mobile APPs. Here’s the scenarios that you 
could use this plugin: you want to develop a mobile app or app on mac, and the 
app is to show the list of your blogs(in category, tag, or keywords), after 
the app user click one item in the blog list, you would like to show him the 
detail page of the item, but the logos/banners/sidebar of blog is suitable 
only for a desktop other than a mobile device or you want to do something 
different. In the case here, wp_app_json mayble could help.
