I worked through your Guestbook example up to adding the button to launch the camera to take photos. Then I attempted to export the project to Android and to iPhone.
1. Exporting to Android: Tersus didn't create any files on my hard drive.
2. Exporting to iPhone: Files were created. After double-clicking the Guestbook.xcodeproj file XCode was launched successfully. It reports errors and warnings. The build fails, after I click on XCode's "Run" button with iPad 5.1 selected. See attached images.
Any comments and work-arounds - especially for the problem with the Android export, where nothing is exported, would be appreciated.
For best results, use the Firefox browser..
