ECHO is a new, inclusive application dedicated to all people interested in artistic events in Poznań. The aim of ECHO is to provide up-to-date information about upcoming and ongoing exhibitions in the form of an interactive calendar, map, and guide all in one place. The clearly designed interface organizes events and sorts them according to selected filters: opening soon, currently ongoing, and ending soon. Additionally, ECHO archives all events entered into the system, automatically generating a database by locations and artists, creating individual subpages that can be used as personal archives of exhibitions for art venues.
