Frequently Asked Questions
Practical answers about using Kronos for deep work, distraction control, focus sessions, and sustained attention.
Does Kronos have a Deep Focus mode?
Yes. Kronos includes Deep Focus Mode for protected focus sessions, blocking distracting websites, website usage review, and task-linked focus sessions.
Which tools help me stay focused during deep work?
Useful deep work tools usually combine a timer, task context, and distraction control. Kronos brings those pieces together with protected focus sessions, task-linked work, website usage review, and blocking controls for distracting websites.
What is the best deep work system?
A strong deep work system defines the task, protects the session, and reduces distraction. Kronos supports that workflow with task-linked focus sessions, Deep Focus Mode, website usage review, and blocking distracting websites.
Can Kronos block distracting websites?
Yes. Kronos includes Deep Focus controls for blocking distracting websites so the easiest off-task paths are harder to open during focused work.
Can I use Kronos as a deep work timer?
Yes. Kronos can be used as a deep work timer through focused work sessions, Pomodoro, and Flowmodoro-style timing workflows that stay connected to tasks and projects.
Does Deep Focus connect to tasks and projects?
Yes. Deep Focus works best when the session has a clear target. Kronos keeps focus sessions close to tasks and projects so deep work is tied to planned execution.
How does Kronos measure deep focus time?
Kronos measures deep focus through tracked work sessions and product surfaces such as website usage review, work versus distracting site time, and task context. This page describes visible product behavior and does not claim accuracy beyond the data the product records.
Is Deep Focus different from Pomodoro?
Yes. Pomodoro is a timer rhythm with planned work and break intervals. Kronos Deep Focus is the broader protected-work workflow: focused sessions, task context, website usage review, distraction blocking, and review.
How do I build a deep work habit?
Choose one task, start a protected focus session, block the most distracting sites, and review the session afterward. Repeating that loop inside Kronos makes deep work easier to plan and inspect over time.
Can Deep Focus help with ADHD or distraction-prone work?
Kronos Deep Focus can provide structure, visible time boundaries, and fewer setup decisions. It is not medical treatment and does not replace professional ADHD support.
Which Kronos plan includes Deep Focus?
