Setting up App on Chartboost.com

Go to chartboost.com/dashboard and create an App, you need to create one for iOS and another for GooglePlay, and another for Amazon if you use them all. Once you have done this you can hover "App ID" that is located below the App name. Note that you can unique ids for each platform. Now you can test the ads and you should see a "Chartboost Success Ad" showing. Now you app is "registered" with Chartboost. To display real Ads you now have to create a campaign for that target or add the apps to already existing campaigns. Now make sure to go into the App in the Chartboost dashboard and make sure that "Test Mode" is disabled. After a few minutes you should see real ads.

More screen works if you have Apps added to it. To add your own apps you obviously need other apps to add first. If you release the first app for ios, android or amazon then it is likely that you don't have other apps and so you won't be able to add your apps to the more screen.
