What is a web app?

To me, a web app is basically a website that is specifically optimized for the iPhone. The site can be anything from a standard small-business brochure site to a mortgage calculator to a daily calorie Tracker-The content is irrelevant. the defining characteristics of a web app are that the user interface is built with web-standard technologies, it is available at a URL (public, private, or behind a login ), and it is optimized for the specifics of the iPhone. A web app is not installed on the phone, is not available in the iTunes App Store, and is not written with objective-C.

What is a native app?

In contrast, native apps are installed on the iPhone, have access to the hardware (speakers, accelerometer, camera, etc .), and are written with objective-C. the defining characteristic of a native app, however, is that it'S available in the iTunes App Store-A feature that has captured the imagination of hordes of software entrepreneurs worldwide, myself encoded ded.

Different applications have different requirements. some apps are a better fit with Web technologies than others. knowing the pros and cons of each approach will help you make the right demo-about which path is appropriate for your situation.
