Apple is planning to launch a dedicated video game app on its devices, which will be pre-installed on iPhone, iPad, Mac and Apple TV later this year. The app will serve as a game launcher, centrally display in-game achievements, leaderboards, communication records and other activities, while providing editorial content, access to the App Store game section and promoting the Arcade subscription service. The app will replace the existing Game Center and is part of Apple's efforts to enhance the gaming experience on its devices. Currently, games and in-app purchases contribute about two-thirds of App Store revenue.
