Chunk

Chunk is a native macOS time-blocking and task-planning app that combines tasks with Apple, Google, and Outlook Calendar events. It helps individuals schedule focused work around existing appointments using timed blocks, recurring routines, countdowns, and transition alerts.

Chunk

Time blocking built around the calendar

Chunk is a native macOS time-blocking and task-planning app that organizes work around a calendar. It combines task lists, Apple Reminders, and synced Apple, Google, and Outlook Calendar events in one workspace, allowing users to move between tasks and a schedule while planning a day, week, or month.

The app is designed for calendar-centered daily planning: users can turn tasks into timed blocks, work through a visible countdown, and use fullscreen transition alerts when a block ends. It is intended for people who want to convert open calendar time into scheduled work rather than manage tasks separately from their appointments.

Core features

Calendar-centered planning

Plan on day, week, or month timelines with tasks and Apple, Google, and Outlook Calendar events displayed together. The calendar editor opens beside the selected block for quick changes.

Two-way calendar workflow

Turn tasks into calendar events and events back into tasks through two-way calendar synchronization. Synced events can include video-call access and invitee information.

Task lists and details

Keep work in searchable smart lists, custom lists, groups, and Apple Reminders. Tasks support notes, checklists, attachments, deadlines, and recurrence.

Time blocking and templates

Drag individual tasks or reusable templates onto the calendar to assign a duration and create focused time blocks. Templates can represent repeatable routines.

Timer and transition cues

Use a built-in countdown during a block and receive a fullscreen alert when it ends. The alert lets you mark the task complete or reschedule it.

Offline access and export

Keep the app available without an internet connection on paid plans, and export a schedule as PDF or CSV when a shareable copy is needed.

Practical use cases

  • Daily time-block planning

    Review appointments and open time in one calendar view, then drag priority tasks into available spaces to create a realistic schedule for the day.

  • Calendar-led weekly planning

    Plan a workweek around existing meetings by viewing tasks and calendar commitments together, while using separate day, week, or month layouts for different planning horizons.

  • Recurring routines

    Create a repeatable routine from a template, or use recurring tasks for work that needs to happen on a fixed schedule or after a set interval.

  • Focus and task transitions

    Run a focused work block with the countdown visible, then use the fullscreen end-of-block prompt to complete or reschedule the task before moving to the next activity.
