Give one task a clear stopping point
Timeboxing means deciding in advance how much time to spend on an activity. Instead of waiting until an open-ended task feels finished, choose a limit, work within it, and review the result. This timer supports a single task with a limit from one to 480 minutes.
How to use this tool
- Name a task with a concrete result, such as Draft the opening paragraph.
- Enter a time limit in minutes and start the timebox. Pause and resume if an interruption requires it.
- At the completion sound, stop and review what you produced. Decide whether to finish, narrow the task, or start another timebox.
A practical example
Give inbox sorting 15 minutes. When time ends, review the remaining messages and decide what needs a separate task instead of extending the session without a decision.
Common questions
How is timeboxing different from Pomodoro?
A timebox is a chosen limit for a task or activity. A Pomodoro timer alternates repeated focus sessions and breaks. Use a timebox for a single bounded effort and Pomodoro when you want a repeating work-and-rest schedule.
Is my timebox saved if I reload?
The task and timer state are saved in this browser. A running timebox uses its saved end time to calculate what remains. Keep the page open and the device awake for the completion sound.
