Currently events or academic activities in the Multidisciplinary Unit Tizimin (UMT) are informed through social networks, posters and direct messages by the coordinators of the degrees offered there; however, this strategy has not resulted effective since students visually discriminate posters and social networks are forbidden by institutional policies, causing that students do not find out about those events or do so too late. Nowadays, the use of instant messaging on smart phones has resulted in an effective way to allow communication among people, which is why this paper proposes the development and implementation of a mobile application based on a design pattern known as publish-subscribe, to allow students to know in time about events or activities performed in the UMT, resulting in a greater attendance and participation. Likewise, a usability study is presented in which the prototype of the proposed system is assessed.
