Everything you need to get things done

Powerful tools, seamlessly integrated. Reduce context switching and stay in flow.

Tasks

Not just a checklist. View tasks in a list or on boards organized by Priority, Energy, or Eisenhower Matrix. Focus Now mode limits you to 3 tasks — because that's all you can truly commit to in a day. Overdue tasks turn red and surface in the Attention Needed widget.

Schedule

See your day as blocks, not lists. Events for fixed commitments, Timeblocks for dedicated focus time, and Threads for long-running projects with hour-based goals. Link tasks and notes to a timeblock so you know exactly what to work on.

Notes

A rich text editor that stays out of your way. Type / for slash commands — headings, lists, code blocks. Zen Mode goes full-screen. Link notes to other notes or tasks using [[Note Title]] syntax. Your notes aren't isolated — they're connected.

Routines

Step-by-step workflows with built-in timers. The Routine Player guides you with audio announcements at key thresholds. When a routine completes, it can auto-increment a counter, mark a habit done, or create a log entry.

Counters & Habits

Track anything with a number, or build streaks with daily habits. Counters handle glasses of water, books read, kilometers — with configurable units and targets. Habits show a calendar grid with automatic streak tracking.

Projects

The top-level organizer. Every task, note, event, routine, counter, and document lives inside a project. Each project gets its own dashboard, color theme, and feature toggles — enable only what you need.

A day in the life of Priya, the Student

Morning

Priya wakes up and checks her Dashboard — two assignments due this week, a group project meeting at 2pm. She runs her Morning Routine: Gratitude Journal, Mindfulness Meditation, Reading. The built-in timer keeps her on track.

Afternoon

Between classes, she opens her Notes to jot down lecture points with slash commands. Her Timeblocks show a 2-hour study session blocked for the library. The linked tasks remind her exactly what to work on.

Evening

Before bed, she checks off her Habits — "Read 20 pages" ✓, "No social media after 9pm" ✓. Her streak hits 14 days. Tomorrow's timeblocks are already set.
