Frequently Asked Questions
Running a Deep Work Session and Actually Tracking What Broke Your Focus
Most focus tools stop at the timer. A focus timer that also logs distractions as they happen gives you something more useful afterward: not just how long you focused, but what actually pulled your attention away during that time — which is the part most people can't remember accurately after the fact.
Choosing a Session Length That Fits the Task
Rather than a fixed interval, this timer offers preset lengths from 15 to 90 minutes, plus a custom option for anything else. A 15-minute block suits a quick, well-defined task; a 90-minute block fits something closer to what Cal Newport, in his book Deep Work, describes as work requiring sustained, distraction-free concentration to produce something genuinely difficult to replicate. Matching the session length to the actual task matters more than defaulting to the same duration every time — a 90-minute block for a 20-minute task just invites your attention to wander before the timer runs out.
Logging Distractions Instead of Just Noticing Them
Every time something pulls your focus, typing it into the distraction log takes a few seconds and does two things: it gets the thought out of your head without fully breaking your session, and it builds an honest record of what's actually competing for your attention. Reviewing that list afterward is often more revealing than the raw session length — a string of entries all mentioning the same notification or the same train of thought points to something worth addressing directly, like muting a specific app during focus blocks.
What the Focus Score Actually Measures
The Focus Score is a number this tool calculates from your own session history — it factors in your average session length and how many distractions you logged per session, rewarding longer sessions with fewer interruptions. It's worth being clear about what this is and isn't: it's a simple, self-referential score based on the sessions you've logged here, not a scientifically validated measure of cognitive focus or attention span. Use it to track your own trend over time — whether your recent sessions run longer and cleaner than your earlier ones — rather than comparing the raw number against anyone else's.
Ending a Session Early Still Counts
If a session gets cut short, ending it manually still logs the elapsed time as long as at least a minute has passed, rather than discarding the session entirely. This matters for keeping an honest record — a 40-minute session that got interrupted and ended at the 25-minute mark is still useful data, and excluding it from your history would understate how much real focus time actually happened that day.
Frequently Asked Questions
Is the Focus Score comparable between different people?
No — it's calculated purely from your own logged sessions and is meant for tracking your personal trend over time, not as a standardized measure to compare against someone else's score.
Does logging a distraction pause the timer?
No — the timer keeps running while you log a distraction. The log is meant to capture the interruption quickly without fully breaking your session's flow.
What happens to my distraction list after a session ends?
The distraction count for that session is saved with it in your session log, and the active distraction list clears so the next session starts fresh.
Will my session history be there if I come back tomorrow?
Yes, as long as you're using the same browser on the same device — sessions are stored locally in your browser and persist across visits until cleared.

The Distraction List Is the Real Value Here
Anyone can time a work session. What actually changes behavior is seeing, in your own words, what kept interrupting it — and noticing the same distraction show up three sessions in a row is usually a clearer signal than any single number the timer produces.
