Post Description

Hi HN Dudley here, tech lead on Chunk.

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.

Native macOS, not Electron. One-time lifetime licence, 7-day free trial, no card. We use it every day — happy to answer anything.
