While getting an app into Android stores is fairly easy, Apple's App Store has an approval process that's often strict, confusing, and not always consistent. There have been grumblings in the developer community because PhoneGap apps are thought to be nearly impossible to get into Apple's App Store. Originally, Apple rejected all hybrid apps, but after about 6 months, they started allowing them and will no longer reject applications solely because their user interface is built using HTML. In fact, many of Apple's own apps or advertising platforms for iOS are entirely built with HTML/CSS/JS. Apple is rejecting some PhoneGap apps because they are essentially nothing more than webpages wrapped in a browser, marketed as an app.
