Deep Work Timer
Longer work, fewer restarts
The Deep Work Timer is the longer-session version of the focus tools. It starts with a 90-minute work block, a 20-minute short break and two work rounds before the longer break. It is aimed at tasks such as sustained writing, analysis, design or programming where repeatedly rebuilding context is costly.
Ninety minutes is offered as a convenient preset, not because every person has a ninety-minute biological attention cycle. If the work quality drops earlier, shorten it. If you are still working well at the end, finish a natural stopping point and adjust the next session deliberately.
Protect the context you built
Prepare the block before it begins: open the material you need, close unrelated communication, and decide what output should exist when the timer ends. A long session that starts with twenty minutes of searching for files is not really a long focus session.
Keep a small capture list beside the work. Put unrelated ideas, messages to send and things to look up on that list instead of acting on them immediately. The list protects the current task without asking you to trust yourself to remember everything later.
When Deep Work is the better fit
Long blocks are not automatically better. The useful distinction from the Focus Timer is simply that this page gives more uninterrupted time and fewer round changes by default; both remain fully adjustable.
For work that can be completed in a shorter block, the Focus Timer is usually the cleaner choice. Use Deep Work when the task has a meaningful setup cost and benefits from staying inside the same problem for longer.
Questions people ask
Why offer ninety minutes as a preset?
Some projects benefit from a longer uninterrupted block than a standard Pomodoro. Ninety minutes is simply the starting preset on this page, not a biological rule or a required session length.
When should I use Focus instead?
Use Focus when a 50-minute default and more frequent breaks fit the task better. Use Deep Work when you deliberately want a longer block and fewer round changes.
