MConference is a service consisting of a web application (web page) and mobile application. MConference is used for providing participants of the conferences, congresses with information about the event. The administrator enters information through a web service – the admin panel. All entered data are made available to the web page of the event and in mobile applications (for Android and iOS). For publishing information, we prepared a mobile application for the administrator. For every client we prepare a separate application that is color consistent with the client’s company brand, with the appropriate logo. Nowadays more and more network traffic moves to mobile. It seems natural to offer our clients this kind of service. A mobile application for a conference is a great tool to inform its participants about the conference place and time, directions, hotels, agenda, speakers, etc. A possibility of sending Push Notifications enables the participants to being kept up-to-date about any changes in the agenda or other news.
