Ask HN: Suggestion on which framework to use

I am planning to write an app which should run on iOS, Android and also on a web browser. The app needs to use camera as well as GPS. I also want the app to be available from appstores. I understand that I need to use HTML5 and other mobile web technologies. IS there some framework that can make writing such an app easier, preferably, having only a single codebase.

Have you looked into Titanium Mobile? http://www.appcelerator.com/products/titanium-mobile-applica...
