This is on our list of things to add (http://ideas.bluecherrydvr.com/forums/45409-general/category/33946-mobile-apps), but at the moment we do not have a mobile application.  We do have web based viewing that will work on Android or iOS devices, which can be access using https://hostname:7001.

We have worked with the developer of IP Cam Viewer (Android: https://market.android.com/details?id=com.rcreations.ipcamviewer&hl=en or iOS: http://itunes.apple.com/us/app/ip-cam-viewer-pro/id402656416?mt=8) to add support for Version 2 in that application.  If you want to be notified when we do release a mobile app, click the link(s) below:
