Cfait — Open Source Productivity App

Take control of your TODO list.

Cfait is designed for speed and stability using Rust, it puts you in control of your data with a local-first approach that syncs seamlessly across your devices.

Why Cfait?

• Open Source & Cross-Platform: Use Cfait on Android, Linux, and Windows. Your tasks adhere to open standards (CalDAV and iCalendar), not walled gardens.
• Syncs Everywhere: Fully compatible with Nextcloud, iCloud, Radicale, Xandikos, and other standard CalDAV servers.
• Offline First: Optimistic UI updates mean you never wait for a server response. Use the persistent "Local" calendar for offline tasks and migrate them to a server later.
• Smart Input: Add tasks naturally. Typing "Buy cat food !1 @tomorrow @@grocery_store ~15m" automatically sets the priority, due date, location and duration.

Productivity Features

• GTD Workflow: Mark tasks as Needs Action, In Process (>), Cancelled (x), or Done.
• Hierarchy: Create sub-tasks, promote children, and organize nested lists.
• Dependencies: Link tasks using "Blocked-by" or "Child-of" logic (RFC 9253).
• Tags & Aliases: Organize with hierarchical tags (e.g., #work:backend). Create inline aliases (e.g., #shed:=#home_improvement and @home_improvement:=@@home) for rapid filing.
• Sane Sorting: Tasks are sorted by Status > Start Date > Due Date > Priority.

Smart Syntax Guide
When adding or editing a task, use these shortcuts:

• !1 to !9: Set Priority (1 is Critical, 9 is Low).
• @date: Set Due Date (e.g., @tomorrow, @2025-12-31, @2w, @in two weeks).
• ^date: Set Start Date (hides task until date).
• ~duration: Estimate time (e.g., ~30m, ~2h).
• @every X: Set Recurrence (e.g., @daily, @every 2 weeks).
• @@loc: Set Location (e.g., @@home, @@"hardware store").
• url:http://perdu.com: Attach a URL.

Advanced Search
Find exactly what you need with powerful filters:

• is:active / is:done: Filter by status.
• ~<30m: Find tasks taking less than 30 minutes.
• !<3: Find high-priority tasks.
• @<today: Find overdue tasks.
• @@home: Find tasks at a specific location.
