I used to force creative work into timed blocks.
Set a timer for 90 minutes. Write. When the timer ends, stop — even if I'm mid-sentence.
It felt productive. But it killed flow.
Because creative work doesn't respect timers. Sometimes you need 30 minutes. Sometimes you need four hours.
That's when I discovered stopwatch mode.
Timer mode: Set a duration. Work until it ends. Good for structured tasks with clear endpoints.
Stopwatch mode: Start working. End when you're done. Good for creative work with unpredictable flow.
Deep Focus has both. And knowing when to use each changed everything.
Writing: You don't know how long a draft will take. Start the stopwatch. Write until the idea is out. Then stop.
Design: Flow state doesn't fit in 60-minute blocks. Start the stopwatch. Design until you hit a natural stopping point.
Problem-solving: Some bugs take 20 minutes. Some take three hours. Start the stopwatch. Solve the problem. Then stop.
I use timer mode for predictable work:
I use stopwatch mode for creative work:
Timer mode creates structure. Stopwatch mode creates space.

Not all work fits in boxes. And forcing it into boxes kills the work.
Stopwatch mode gives you the blocking and focus of a timer without the artificial deadline.
You're still in a focus session. Distractions are still blocked. But you're not racing a clock. You're following the work.
I finish more creative work in stopwatch mode than I ever did with timers.
Because I'm not stopping mid-flow to "respect the timer." I'm working until the work is done.
And when it's done, I stop. No guilt. No pressure. Just completion.
Use timers for structure. Use stopwatch for flow.
