Abstract
The purpose of this paper is to show not only the process of creating an application from scratch on different mobile platforms but also evaluate its performance. A multithreading craps game simulator is developed using Java, Objective-C and C# in order to run on Android and iOS platforms. The application is evaluated according to the user and developer criteria such as execution time, lines of code [4, 5], application size, CPU usage, memory usage, data usage and using native Integrated Development Environments (IDEs) such as Android Studio and Xcode or a common IDE such as Xamarin.
