My reply to this Cross-Platform Mobile Visual Development – a Tool Comparison. I tried posting this in the comments but that didn’t work. Tiggzi: the cloud-based mobile app builder should definitely be there.
Home page: http://tiggzi.com
Genesis: The cloud-based HTML5 and hybrid mobile app builder.
Version: Cloud (and white label)
Licensing: Free and premium — http://tiggzi.com/pricing
Download: Nothing to download, cloud-based
Sample application: http://tiggzi.com/common/showcase/browse.seam
Additional: The app is built with jQuery Mobile/HTML5. Connected to any REST API, tested, and exported as mobile Web, Android or iOS. PhoneGap is used for access to native device features.
