Developers say there are too many junk apps in Apple, Inc.'s App Store for the iPhone and iPod touch. Developing an application for Apple's App Store can be costly if Apple rejects it, as Apple did for I Am Rich and others. Developer Glenn Howes had to change his Lullabies app and says Apple should provide guidelines on what apps are acceptable.

Many things in application development can be left to interpretation, but developers need the best interpretation of what Apple wants in its App Store before developing a killer app. In the seven months since launching the App Store, Apple has accepted hundreds of thousands of applications, but it has also doled out its share of rejections.Some of the better-known rejections include: I Am Rich, Pull My Finger, Podcaster and the most recent South Park App. While I Am Rich did nothing other than to show the user could afford to pay $999.99 and Podcaster competed with Apple's Podcast section of iTunes, the flatulent Pull My Finger and South Park were considered offensive.
