Chunk is a macOS menu bar app for time-blocking. It opens with Cmd + / and slides down over whatever you're doing - including fullscreen apps. There's also a live countdown in the tray for the current block.
Click-and-drag to create blocks, day/week views, Google/Outlook/Apple Calendar sync, Apple Reminders integration, and a Todo mode where tasks can be dragged onto the timeline. Templates and Routines let you build an ideal day once and auto-apply it on chosen weekdays.
There's a local MCP server, so you can ask Claude Desktop to plan your day and it reads/writes blocks directly.
