There is an increasing demand for applications in which users can easily browse different events organized by different institutions or organizations in a single place. Among these events are the following: theater or movie shows, cultural programs, presentations, meetups, etc. Most of the institutions (e.g. theaters) have their own web pages, where the programs along with the related news and pieces of information are published. These websites differ from one another and sometimes it may become difficult for the users to digest the required pieces of information from them. The aim of the software system is to offer a solution for this problem. With a single mobile application, using a uniform user interface they can browse the program of all those institutions, which uploaded their events into the system through the web administration interface. In the current version of the system mainly theaters are targeted but the solution will be generalized to support other institutions too. The article presents the PlentyGO system, which contains two client applications and a central server.
