Chunk

Chunk is a time blocking app for Mac. It presents tasks on the left (smart lists, projects, Apple Reminders, recurring tasks and templates) and calendars on the right, viewable as a day, week or month. Users can drag tasks onto the timeline, create blocks, apply recurring templates, and receive a live countdown in the tray with a fullscreen alert when each block ends. External calendar events can be edited and synced back to their source calendar, with a lock option for read-only events. Chunk includes an optional local MCP integration for Claude Desktop that runs on the Mac. The website states a 7-day free trial with no credit card required, a one-time purchase after the trial, and requires macOS 12 or later. A separate iPhone app is described as coming soon.
