Chunk is a native macOS menu bar app for time-blocking your day. It floats above all windows – including fullscreen apps – so your schedule is always one shortcut (Cmd+/) away without ever leaving your flow.

Key things I built into it:

- Drag-to-create/move/resize time blocks on a 24-hour timeline, with a live countdown in the tray icon - Two-way sync with Google Calendar and Outlook (create, move, resize, delete events back to source); Apple Calendar read-only - Things-style three-column task sidebar: lists | tasks | day view, with Apple Reminders integration so you can drag reminders onto the timeline - Templates + Routines – build a reusable day structure and auto-apply it on chosen weekdays - Fullscreen notifications that flash the block name across your entire display at task transitions - Claude AI integration via a local MCP server – Claude can read/create/edit your schedule, todos, and templates. Everything runs on-device; nothing leaves your Mac except what Claude itself processes - Built with Tauri 2 (Rust backend + React/TypeScript) so it's fast and lightweight, not Electron

It's a paid app (one-time purchase) with a free trial. No card required to try it – just download and run.

Happy to answer any questions about the implementation
