Subtasks let you break down a task while you are already working on it in Focus Mode, without leaving the screen or losing your train of thought.

How to add a subtask in Focus Mode

While in Focus Mode, click the Subtasks icon below the task title or press S. A small input field appears beneath the task. Type the subtask title and press Enter. Add as many as you need, then press Escape to close the input and get back to work.

Working through subtasks

Once added, subtasks appear as a checklist below the main task title in Focus Mode. Tick each one off as you complete it by clicking the checkbox or pressing Space when it is selected. The main task stays open until all subtasks are complete, or until you manually mark the whole task as done.

When to use subtasks

Use subtasks when a task has clear, distinct steps and you want to track progress through them. They are particularly useful for tasks that span more than one session — the remaining subtasks tell you exactly where to pick up next time.

Subtasks do not extend your time block automatically

If you add subtasks and realise the task will take longer than planned, extend your session manually using +. Aftertone will not adjust your schedule without you telling it to.

Editing subtasks in the planning view

Any subtasks you add during a session are visible in the task detail panel in the Calendar view. You can add, edit or remove subtasks from there at any time, not just while you are in Focus Mode.

👉 Try it now — The next time a task grows in scope while you are working on it, press S in Focus Mode and add the subtasks before you do anything else. It keeps the work visible and your inbox clean.
