The applications are created in Xcode, or sometimes using other supported 3rd party programs. The apps can then be submitted to App Store Connect (formerly iTunes Connect), another one of Apple's website for approval the internal review team. Once approved, they can be distributed publicly via the respective app stores, i.e. App Store (iOS) for iOS and iPadOS apps, iMessage app store for Messages apps and Sticker pack apps, App Store (tvOS) for Apple TV apps, watchOS app store for Apple Watch apps with watchOS 6 and later, and via App Store (iOS) for earlier versions of watchOS. macOS apps are a notable exception to this, as they can be distributed similarly via Apple's Mac App Store or independently on the World Wide Web.
