Nirvana is a GTD-focused task manager built to implement David Allen's Getting Things Done system with minimal friction — offering inbox capture, next actions, waiting for lists, someday lists, and project review in a clean, opinionated interface. Founded in 2009 and rebuilt multiple times, Nirvana is a favorite among GTD purists who want an app designed specifically around the methodology rather than a general tool adapted to it. Its focus mode surfaces only the tasks relevant to a specific context or area, reducing the overwhelm of a full task list.
