Hi, AppGyver dev here. Our platform expands on the web view approach, allowing you to leverage existing web development experience when getting started.
Yeah, it's HTML and JS - but whereas Cordova provides you with one web view to build your app in, Steroids applications have multiple views joined together with native navigation. We ship with a lovely CSS framework by default to make building UIs a snap. The command line features livereload, so your changes can be reflected instantly on the device. And because it's Javascript, you can debug using the tools in Chrome and Safari - a vast improvement over printlns.
