LeaderTask
Plan tasks and projects on Windows with LeaderTask's calendar, Kanban boards and offline task management. A free plan is available with paid upgrades.
What is LeaderTask?
LeaderTask organizes personal tasks and shared projects in a Windows desktop app. Use calendar views to plan a day or a longer schedule, or arrange work on Kanban-style boards. Notes and files can stay alongside tasks rather than in a separate planning document. The publisher also describes offline task management, with updates applied when an internet connection returns.
The free plan is limited to 100 cards, 10 projects and 3 boards. The pricing page places cross-device sync, attachments and recurring tasks in a paid tier, with assignments and shared projects in a further collaboration tier. Check those plan boundaries before choosing it for a team: the Windows feature overview describes capabilities across the product, not a promise that every feature is free.
