Displaying different app name in App Store and on home screen

Question

Apparently some apps display a different name on the app store details page than they do once downloaded and placed on the home screen.

This makes good sense since space

Answer 1

The name used on the app store applications page detail is defined on iTunes Connect when you upload the app.

The name of your binary is in your Project Setting underneath the Info panel (Bundle display name) when you select your target.

Answer 2

Just to elaborate on @Ganzolo's answer, these images show where each of those are defined. The home screen title is defined in your app's info.plist file in the bundle display name string, and the App Store page name is set when you click add new app in iTunes Connect
