Arca is a team task manager built for clarity without complexity. Whether you're running a project, managing a team, or just trying to keep track of what needs to get done, Arca gives you everything in one place, no more scattered spreadsheets, forgotten emails, or endless status meetings. ORGANIZE WORK YOUR WAY Break your workspace into folders and lists that match how your team actually works. Group tasks by phase, category, milestone, or team, then drill into exactly what matters without the noise. TASKS WITH FULL CONTEXT Every task in Arca is a complete record of the work: • Rich title and description • Status and priority (Urgent, High, Medium, Low) • Assignees, so ownership is always clear • Start date and due date • Labels and custom tags • Subtasks for breaking down complex work • Dependencies to track blockers • Comments, @mentions, reactions, and file attachments No more digging through Slack threads or email chains to find context. It's all on the task. MULTIPLE VIEWS FOR EVERY SITUATION One size doesn't fit all. Switch between views to get the perspective you need: • Table: spreadsheet-style grid for bulk updates and triage • Board: drag-and-drop kanban cards grouped by status, priority, or assignee • Calendar: tasks plotted by due date for deadline planning • Timeline: task bars across a time axis for scheduling and spotting overlaps Save any view with your filters and sorting intact, and return to it instantly. REAL-TIME COLLABORATION Your team stays aligned without constant check-ins: • Comment directly on tasks and @mention teammates • Get notified the moment something changes that affects you • React to updates with emoji reactions • Know who's responsible for what at a glance DASHBOARDS & INSIGHTS Stop manually tracking progress. Arca's dashboards surface the big picture, task completion rates, workload by assignee, tasks by status, so you always know if work is on track and where bottlenecks are forming. BUILT FOR TEAMS Arca is designed around shared workspaces with role-based access. Invite your team, assign work, and keep everyone moving in the same direction, without the overhead of complex project management tools. Whether you're a small team moving fast or a growing organization that needs structure, Arca scales with you. Download Arca and bring clarity to your team's work.
