As a prototype HTML5web app, Twidy—a combination of 'Twitter' and 'today'—isan attempt to bring together two primary concerns of the mobileindustry: productivity and the social broadcast model.

    Like other to-do apps,Twidy's design supports productivity through an easy-to-useinterface that allows the user to set categories, colours, and timesfor separate tasks. What makes the application novel is that itsusers can communicate with their Twitter followers any current tasksthey have set and any tasks they have completed—all withoutbreaking workflow by having to open another app.
