Zehano offers two timer styles. The Deep Work Timer gives you one continuous countdown. The Pomodoro Timer alternates focus and rest. These controls provide structure; neither timer observes your attention or guarantees better work.
When a shorter cycle can fit
Try an alternating timer when getting started is difficult, the work has small units or you want a visible reminder to pause. The default is twenty-five minutes of focus and five minutes of rest. Both values are adjustable before starting. A pause preserves the remaining time.
When a longer session can fit
A continuous timer may suit work that needs time to load context, such as reading a complex document or drafting a section. Choose a duration you can comfortably protect. Let interruptions change the plan when necessary; an uninterrupted streak is not more important than the work or your needs.
Run a fair personal comparison
Use similar tasks on different days and note what you finished, how often you paused and whether the duration felt practical. Do not compare a difficult research task with routine email and attribute the whole difference to the timer. Keep the method that helps you start and finish useful work, and change it when the task changes.
