Mobile web apps require mobile devices, which have a web browser on the phone to use. HTML and Ajax components (and gradually HTML5) are generally suitable for use, even though the use of RIA (enriched internet application) for applications such as Flash, JavaFX and Silverlight are not specifically written for the mobile. To present knowledge in a concise, action-oriented manner, the use of RIA technology is restricted by simple mobile web apps. The use and not limitation of web technologies on the underlying delivery platform varies from Mobile App Developers. Do you believe other differences exist?
