If you want to have immediate access to your favorite sites in an app-like way, you can use Google Chrome's Create desktop shortcut feature.
It enables you to create within seconds a shortcut of a website, that will be placed on your desktop or applications menu. Just to be clear, this is not a real app, but a desktop shortcut to Chrome's viewer, hiding the browser bars, so it does look like an app. The shortcut icon will be the website's favicon.ico image.
In order to create your own desktop shortcut on any operating system supporting Google Chrome (Windows, Ubuntu,...) you can do the following:
1) Open your target website on Google Chrome
2) Click on Chrome's menu (top-right corner)
3) Go to More tools and Create application shortcuts
4) Tick on the kind(s) of shortcuts you want to create
5) Click on Create
