It is possible have an app especifically for a country?

Hi, I want to have an app only for one specific country, and the same app (same id) for the rest of the world but the code of the apps diferent. It is possible?

Yes when you are ready to submit your app to the app store you may specify what countries you would like your app to be available in. But in regards to if you want a app with different functionalities to go to a different country you may just want to submit two app's ( one going to your specific country and the other going where ever else you want it to go)
