Apple is planning to launch a dedicated video game app on its devices, which will be pre-installed on iPhones, iPads, Macs and Apple TV later this year, Internet reports. The app will serve as a game launcher, focusing on in-game achievements, leaderboards, communication records and other activities, as well as providing editing content, access to the App Store game section, and promote Arcade subscriptions. The app will replace the existing Game Center and is part of Apple's efforts to improve the gaming experience on its devices. Currently, games and in-app purchases contribute about two-thirds of the App Store's revenue.
