Kanban 3

Kanban 3 is a single-purpose task board with three columns: To Do, Doing, Done. You add cards and tap an arrow to slide them right as work progresses. There are no subtasks, no tags, no nested lists—just a flat board for a small number of items.

The free tier gives you one board with up to 10 active cards. The subscription adds unlimited boards, archived cards that move out of your way, color-coded swimlanes, and removes ads. It is aimed at indie developers, freelancers, and students who need a lightweight kanban without the overhead of Notion or Jira.
