A calmer focus timer
A focus block is a single stretch of work — usually 25 or 50 minutes — given to one task, with a clear start and a hard stop. Write one sentence describing the task, take one slow breath, and begin; the timer holds the boundary so your head doesn't have to.
25:00
A soft chime plays when the block ends. Keep this tab open; the title shows the countdown.
The three-legged stool
- A cue
- Something small that marks the start — make the tea, clear the desk, write the sentence above.
- A sound
- The same steady audio every time, so it becomes a signal. Try the free sound mixer in another tab.
- A single task
- One thing. When the chime rings, stand up, breathe, and only then decide what's next.
