App.js is a lightweight JavaScript UI library for creating mobile webapps that behave like native apps, sacrificing neither performance nor polish.

• cross-platform (Android 2.2+, iOS 4.3+)
• themable platform-specific UI designs
• configurable native-like transitions
• automatically managed navigation stack
• built-in widgets for general use-cases

The goal of App.js is to provide a robust starting point for mobile webapps, handling general scenarios, and maintaining compatiblity with other common JavaScript libraries.
