phonegap is a popular set of templates you can use to turn HTML5+CSS+JS into a phone application. it now has a cloud build service that I think you pay for, which makes your app available on all platforms or just builds for all platforms not sure which. you still have to have phone vendor accounts to use it. adobe has their version of the phonegap build system for their one of their Edge CC programs I think.
