We know building applications for each platform–iPhone, Android, Windows and more–requires different frameworks and languages. PhoneGap solves this by using standards-based web technologies to bridge web applications and mobile devices. Since PhoneGap apps are standards compliant, they’re future-proofed to work with browsers as they evolve.
From the team behind Apache Cordova, the Adobe PhoneGap framework is an open source distribution of Cordova and has been downloaded millions of times and is being used by hundreds of thousands of developers. Thousands of apps built using PhoneGap are available in mobile app stores and directories.
