Arca is a task management app built for teams who want clarity without complexity. It helps you capture work, assign ownership, track progress, and collaborate, all in one place, without scattered to-do lists or missed commitments.

​
Why teams use Arca

  • One place for all your work: tasks, calendar, and conversations live together, so nothing gets lost across chat, email, and spreadsheets
  • Clear ownership: every task has an assignee, so there’s never a question of who is responsible
  • Real-time collaboration: comments, mentions, and notifications keep your team aligned without endless status meetings
  • Flexible views: see your work as a list, board, calendar, or timeline based on what you’re planning
  • Progress at a glance: dashboards and insights show how work is progressing across your whole workspace
