Quire

Quire is a Taiwanese project management app designed around the idea that complex goals are best managed as nested checklists. Teams capture a hierarchical tree of tasks and sub-tasks, then visualize the same data as Kanban boards, timelines, calendars, or mind maps. It is used by software teams, nonprofits, agencies, and educators who need depth without rigidity. Notable features include offline-first mobile apps, peer review on tasks, sublist drag-and-drop, and a generous free tier. Quire has won multiple Apple and Google design awards and is popular in Asia-Pacific markets where lightweight, design-led tools beat enterprise suites.
