Apple has just approved the first release of our Nuxeo World 2011 companion app for general availability on the iTune App Store. Check it out here
Because we're using the Titanium Appcelerator platform, a nice side effect is that we also have an Android version that you can download here. (It should also become available soon on the Android market).
A few screenshots to wet your appetite:
The source code for this app is a fork of the "Codestrong" project, and lives in GitHub, under the GPL license.
