About this tool
Run Pomodoro-style writing sprints with a countdown, log words per sprint, and see your words-per-minute trend and finish time.
A writing sprint timer runs a focused countdown, then a break, then repeats — the Pomodoro pattern of a 25-minute interval, a 5-minute short break, and a longer 15-minute break after every fourth sprint. What makes it a tracker rather than a clock is the log: enter the words you produced in each sprint and it computes words per minute for every sprint, your overall pace, whether you are speeding up or slowing down, and how many more sprints your word target actually needs.

Words per minute comes from your own logged sprints, so projections use your real speed.
Compares the second half of the session with the first and tells you which way your pace is going.
Shows total clock time for the session including every break before you start.
Twenty-five minutes is the standard Pomodoro interval and works well for drafting. Shorter 10 or 15 minute sprints suit editing and getting started when a blank page is the problem; 45-minute blocks suit deep revision where the setup cost of getting back into a chapter is high.
It depends entirely on your pace and whether you are drafting or revising. A drafting pace of 20-25 words per minute produces roughly 500-625 words in a 25-minute sprint; that is why the tool measures your own rate rather than assuming one.
Work in a fixed interval — classically 25 minutes — with no interruptions, then take a 5-minute break, and after four intervals take a longer break of 15 to 30 minutes. The method was developed by Francesco Cirillo, and its value for writing is that the interval is short enough to start even on a bad day.
