I assume you are talking about frameworks like Phonegap. The idea behind such frameworks is, you develop an app using web technologies like HTML5,CSS,Javascript. Since these web technologies are supposed to be cross-platform (to some extent), the porting becomes easy with minor tweaks.

Alternatively, if you develop an app say an android app using Android-SDK, then obviously it is gonna work only on android platform and you will have to rewrite the app for a different platform,say iOS.
