Try Corona by Ansca Mobile.

Corona is the world’s No. 1 mobile app development platform and many developers have found that by using it not only do their apps work better, but they get more downloads. That’s because Ansca Mobile has partnered with some review sites and podcasts for apps such as 148apps.com, CrazyMikeApps.com, AppShrink.com, Experimental Game Dev Podcast, and MadDog Podcast.

Another great feature of the Corona platform is that it can quickly publish an app to multiple marketplaces simultaneously: the Apple App Store, Google Play (Android’s new name for its marketplace), Amazon (for the Kindle Fire) and Barnes and Noble (for the Nook Color tablet). And it’s cheap; a yearly subscription is only $349 or $199 if a developer only wants to build to one platform.
