Kanban is a workflow visualization tool for managing your tasks in a highly efficient way. Cards are added to the TODO list, then moved to DOING and DONE.
Limiting Work-in-progress is the cornerstone of Kanban. You can set the desired upper limit to the DOING list in the app settings.
Analyze your performance with the help of a chart, that shows the periodic summary of your activity.
All completed tasks are archived, so you can review them later. Completion time is tracked automatically.
