AnyConf – mobile application and a web service for conferences. Allows speakers and organizers to receive questions from the audience, conduct surveys and votes, provide relevant information about the event. The audience uses service through applications for iOS, Android or through a Web app. Organizers analyze the audience, collect statistics and operate the system through the Web interface for organizers. Our team has designed the application, developed clients for iOS and Android, a Web client for visitors and a Web client for organizers. We were also responsible for the backend of the service and server architecture.
