Fill your day from the Plan queue
Queue the tasks you want done, and Chunk fits them into the free time around your calendar.
Add tasks to the queue
The queue is a short list of tasks you want done on one day. Queue them at Plan, and Chunk finds each one a free time around your calendar.
- Click Plan, the middle of the three icons at the top left. In the compact panel, click Widen panel first.
- Open a list in the sidebar, such as Today.
- Point at a task and click the + just before the info icon, labelled Add to the queue. It turns into the task's number.
- Add the rest of the day's tasks in the order you'd like to do them.
The bar under your lists shows how many tasks are queued and how long they'll take. Each takes the length it last had on the calendar, or an hour if it never had a time.
To take a task out, click its number. To empty the queue, click the × in the bar, labelled Clear the queue.
Fit the queue into a day
- Check the day in the bar. It starts at Today: click it to pick another, or Other day… for a date further out.
- Click Fit into the day. Each task appears on that day as a dashed block, numbered as in the queue.
- Click the button that places them, such as Place 4 tasks. The blocks land on your calendar.
Chunk only uses free time inside your Day hours, set in Settings → Date & Time, and never time that has already gone. It works around every event and block the calendar shows, so a calendar you've hidden doesn't count. Nor do events marked free, or all-day events not marked busy.
Nothing is saved until you place the tasks: Cancel goes back to the bar. Before then you can drag a dashed block to another time. After a drag, Re-fit starts again.
Choose how to fit
There are three ways to fit the queue. Click one and the blocks move at once.
Best fit, the one you start with, fits the most in. It places the longest task first, each in the smallest gap that holds it, so short tasks fill the gaps between meetings.
In order keeps the queue's order through the day.
Spread keeps the queue's order and leaves 15 minutes clear around every block, for a break between things. It can fit fewer tasks.
When a task doesn't fit
Tasks with no room are listed as left over and stay as they are. To put one on the next day with no time yet, open its menu and choose, for example, Put on Tomorrow.
Start at sets the earliest a task can begin, for this fit only. It starts at the beginning of your day hours.
Edit a task from Plan
- Point at the task's row and click the info icon at its end, labelled Edit details.
- Change its notes, day, repeat, priority, deadline or link in the card that opens.
- Press Esc or click outside the card to close it.
Click the row itself to jump to its block, double-click it to rename it, or drag it onto the calendar.
Choose where blocks snap
When you drag, move or resize a block, it snaps to a grid of minutes. Snap to sets how fine that grid is.
- Open Settings → Date & Time.
- Choose Snap to: 5 minutes, 10 minutes, 15 minutes or 30 minutes.
For exact minutes, hold ⌥ while you drag.
FAQ
Does the queue stay if I quit Chunk?
No. It lasts until you place it, switch to Tasks or quit. Switching to Calendar and back keeps it. Placed tasks are ordinary blocks and stay on your calendar.
Why was a task left over when there's a gap?
The gap may be shorter than the task, or come before a task queued ahead of it, which In order and Spread won't go back to. Try Best fit, another day or an earlier Start at.
Why can't I queue a task?
Repeating tasks, tasks split into sessions and finished tasks can't be queued. Nor can reminders Chunk hasn't brought in from Apple Reminders yet.
Can I undo placing the queue?
Yes, with Undo in the message after you place. If you've moved one of those tasks since, Chunk can't undo and tells you so.
