Erm? Your point?
We are not talking about stuff that runs in a browaser but about Apps, get a damn clue.
And yes, the Apps use the same high level paradigms but access via abstraction layers the underlying OS, which they can't in a browser. Hint: browsers sandbox most of the OS away, to exactly prevent accessing it.
E.g. an App can sent or receive text messages (on your android or iOS device) but a similar web page running in the browser can't!
