ZDNet Has TheAppBuilder Top Of The Pile
The AppBuilder: Created by JamPot Technologies, this is a service that offers application templates that help small businesses create native applications for iOS, Android and Windows Phone. You can get as simple or as custom as you want. The service automatically submits your application to the iTunes App Store, Google Play market and Windows Phone Marketplace. Standard tabs include integration code for YouTube and RSS feeds. Later in 2012, JamPot plans support for features that let you include in-app advertising, WordPress integration and HTML5. You can build and preview an app for free; after you submit it for distribution, it will cost you $29 per month, per app under the standard plan.
