Comments on apps, money and marketshare

Most app developers don't make bank on the apps they develop, but a decent sum can be obtained by many according to web sources, a few can and do indeed make bank. The marketshare of IOS and Android is over 96% so it is worth it to focus on these two.

 Android appears to be in the lead according to this source http://www.idc.com/getdoc.jsp?containerId=prUS25450615  .

Another source verifies this

1. Android has hit a new milestone of popularity: it now owns 81% of the world smartphone market, according to a new market research report from IDC. That's not a huge jump. It was knocking on the door of 80% market share last quarter, when it hit 79.3 percent.Nov 13, 2013-link

 So it might be a good idea to focus on Android development, but engines that facilitate porting of your application to multiple operating systems might be preferable.   Unreal Engine appears to do so, and for free.

Once there if the app is for android, google would be a decent partner for ads in case the app is going to be free.  LINK http://developer.android.com/google/play-services/ads.html
