have a 'link' to fast.com on my homescreen, but it's just a shortcut to an url, no 'web app' or am i mistaken?

You can add any website to your home screen.

If the site has some special meta information, it can display like any other app (full screen, its own entry in your multitasking UI). Otherwise it just opens in your regular browser.
