There is a place for hybrid apps but it is a specialized place: If you have so much content that changes so fast and that needs so many variations in rendering that you end up building something browser-ish to render it, as in a large e-commerce site with dozens of product categories, each with specialized presentation requirements, use a WebView in the parts of the app that display that content.

But if you app has a less challenging kind of content to present, use a native app. If you don't, you are not being very nice to your user. In addition to not presenting the nicest UI, you're using up the user's battery and crowding other apps out of memory.
