Chunk

Chunk is a menu bar time block planning tool designed specifically for macOS.

Designed around a low-distraction, high-focus schedule management experience. It can be quickly pulled up from the top right corner of the screen to view, create, and adjust the day’s plan without interrupting the current task; Users can drag the timeline to divide the day into clear colored chunks, or drag tasks directly into the day view to complete scheduling. The software supports Apple Calendar, Google Calendar, Outlook Calendar, and Apple Reminders, making it easy to consolidate meetings, personal schedules, and to-do items in one view. Chunk also provides real-time system tray countdowns, block start and end reminders, reusable templates, and weekly automatically applied routines, suitable for deep work, fixed schedules, ADHD-friendly time management, and users seeking to reduce scheduling friction. Its local MCP integration allows Claude to read and adjust plans through natural language, with data stored locally on Mac, balancing efficiency and privacy.
