A photograph without captions or explanation quietly remains on the everyday screen. This app places an "Interval" before seeing turns immediately into understanding or judgment. It is designed to create the conditions for the gaze to pause. The app includes Sessions for handling the currently displayed photograph, a Library for saving and managing sets of photographs, and Traces for recording past displays. All photographs shown in the app are works by Ryota Sakurai. The photographs are delivered from a server and updated periodically. No personal data is collected or tracked. This app was created as one form of "Between Here and There", a project by Ryota Sakurai.
