title: Cross-platform mobile API for apps that can be listed in all market places
body: <p>Which cross-platform mobile APIs give apps that can be listed in the major market places? I see PhoneGap generates native apps can be listed in the Android, iOS and Windows markets. What are the other options? I strongly prefer free.</p>
  
  <p>The reason I want native apps is to get the free advertising from being able to list them in the marketplace. </p>
  
  <p>To those who marked the question as off-topic: the selection seems to be very limited. In my searches I've only found PhoneGap which satisfies the criteria (cross-platform, produces native code, free). So it's hard to be opinionated or produce spam comments when the selection is potentially singular. Any suggestions on other options would be welcomed before I commit myself.</p>
