Hi Product Hunt 👋
I'm Dudley, and I'm the developer of Chunk.
Some of you might remember Chunk from the v3 launch, when it was a panel that dropped down from the menu bar. People liked the idea but kept telling me the same thing: it was great for seeing the week but restrictive for planning it. So I spent the last few months turning it into a full feature app that has the best of both worlds.
How it works: your tasks sit on one side, your calendar on the other. Drag a task onto a time and it becomes a block. While you're in a block, a countdown tells you how long is left, and a small floating timer stays on screen even if Chunk is closed. When the block ends you get a fullscreen alert where you can tick it off, take more time or push it to later.
What's new since last time:
• A full window with three layouts: Tasks, Plan and Calendar
• Faster Apple Reminders sync, now with notes and priority
• Search across tasks, reminders and calendar events
• Priorities, links and Markdown notes on tasks
• Private iCloud sync between your Macs, no account needed
• Claude can now create tasks and move things around in your calendar for you
It syncs both ways with Google, Outlook and Apple Calendar, so it works alongside whatever you already use.
It's a one-time $29.99, no subscription, and there's a 7 day free trial with no card needed.
I'd really like to hear how you plan your days and what's missing for you. I'll be here all day answering comments.
Congrats on the launch today! I have a couple of questions: Is this just for tasks, and not for actual calendar meetings? In the video, it shows asking Claude to move a 1:1. Is this a task to move the 1:1 or is Claude actually moving the 1:1?
Also, why a separate desktop application and not a browser extension? Just curious.
