About Echo (An App With Shape)
Echo is a diary app designed as an object rather than a traditional interface. Many apps present data only through screens and menus, making it difficult for users to understand how their information is organized and used. Echo explores an alternative approach by representing the diary as a three-dimensional cube that users can interact with and look into. By turning diary entries and their organization into a small, self-contained world, Echo helps users reflect on their writing and develop a clearer mental model of how their personal data is stored and structured.
