One of the biggest differences I made to the growth of my app business was teaching myself the basics of xCode, teaching myself the iPhone app submission process on how to upload an app to Apple, how to set up gamecenter and how to intergrate Revmob and Chartboost into my apps. Once you sign up to the Apple developer program, being able to create an application with reskinning, build, update, publish and add ads to my apps saved me a lot of money and time, in comparison to paying iPhone developers to these small jobs for me. It’s actually much faster as well.
Revmob and Chartboost are among the highest paying ad networks you can add to your apps. I’ve found them much better (higher eCPMs) than other alternatives like iAds, Ad mob, etc and use them in my own apps. Here’s a quick overview of what I do.
