Nimblekit is an great way to get an iPhone application up and running. As of this post there are no apps I know of in the app store that are built with it, but the potential for this to be a platform that web developers can use to develop enterprise level applications that can integrate with some funky written javascript and XML is pretty phenomenal.

You don't need any Obj-C knowledge, although I'd recommend a fundamental knowledge of the XCode SDK. I think this app is great for prototyping apps withing 2-3 days instead of within 4-5 weeks and the web team can build something with their designers before handing over to Obj-C developers which is very empowering.

Despite this, I think there is a very real chance that apps made with NimbleKit will actually behave so well that they are accepted straight into the app store with much less expertise and development time as truly 'native' apps.

Love it, top work guys! Can't wait to see more features and some more integration with the OS such as SQLite support
