An application that is designed and programmed for only one mobile platform. So if it is needed for both iOS and Android, it has to be developed twice, one application for each platform – though with the same functionality. Native apps react faster than those in a browser (web apps) and provide more features (such as offline data storage support) generally. In Ackee, our primar concern is development of native applications for both iOS (in Swift) and Android (in Kotlin), as this is the best quality solution.
