Chunk โ€“ The Minimalist Menubar Task Timer for macOS

Chunk is a lightweight menubar app for macOS that helps you time-block your day with ease. Designed for makers, freelancers, and anyone who thrives on structure, Chunk keeps your plan visible and your focus sharp โ€” without the bloat of traditional productivity tools.

๐Ÿง  Why Chunk?

Chunk was built to solve a simple problem:
Planning your day shouldn't get in the way of doing your work.

Instead of overwhelming you with features, tabs, or integrations you don't need, Chunk lives quietly in your menubar โ€” always accessible, never distracting.

๐Ÿ”ง What You Can Do with Chunk

  • ๐Ÿ•’ Time-Block Your Day
    Plan your day using "chunks", focused blocks of time for specific tasks. Add, edit, and reorder them quickly.

  • ๐ŸŽจ Full Customisable
    Chunks are full customisable. Pick your colour, duration, emoji etc...

  • โฐ Stay on Track with Alerts
    Get notified when a new task begins. Fullscreen notifications make sure you never miss a transition.

  • ๐Ÿ“… Sync with Your Calendar
    Keep everything in one place by syncing with your Apple, Google or Outlook calendar.

  • ๐Ÿ” Save Templates & Routines
    Create reusable task templates that load with a click or daily routines that auto load on selected days.

  • ๐Ÿ“Š Track Your Progress
    See how much of your day you've completed with a visual progress bar in the menubar.

  • ๐Ÿง˜โ€โ™‚๏ธ Built for Focus
    No long form calendars. Just your plan for today, your time, and your focus.
