We developed a mobile application for the hockey club SKA. The new app make it possible for fans to check match schedule, information on the team and much more. Our team faced an interesting challenge to unite all the supporters on the stadium with a mobile application. We came up with "Light show": each device running on iOS or Android, interchanged the colors of the team in time with the music synchronously with thousands of other devices.
Working on the project, two main tasks have been completed: synchronicity and stable work with high loads. The following technologies were used: in the Microsoft Azure cloud, we developed our server backend with the administrator's web interface built with ReactJS; SignalR protocol provided us with synchronization, and Microsoft Xamarin allowed us to create applications with a single code for Android and iOS.
