This document discusses building app-like experiences without actual apps. It compares apps to webapps, noting apps are single-platform while webapps are multi-platform, and apps have full hardware access while webapps have limited access. It recommends using frameworks like iUI and jQuery Mobile to create responsive webapps that work across devices without native apps. It also provides examples of incorporating barcode scanning into webapps by linking to scanning apps on iPhone and Android platforms.
