How to track your own attention at work (a quantified self guide)

Start with one question and cheap tools. Use a paper tally of interruptions, a kitchen timer that prompts you to note what you are doing, and a fifteen-minute weekly review. Paper wins for tracking energy and work you do away from the screen. Dayflow, a free Mac app, helps when you keep forgetting to log, because it records your screen and turns the day into a timeline on its own.

You close the laptop at six and try to name what you did. There were the two calls and the long thread about the launch date. There was a document you opened four times and never finished. The rest is fog. You know you were at the desk all day, but you are much less sure where your attention was.

If you like data, the natural response is to measure it. You already count steps and sleep, so why not focus? Then the spreadsheet grows columns nobody reads, and after two weeks it quietly stops. You did not lack discipline. Attention is hard to see from the inside, and most tracking setups ask you to remember to log at exactly the moments you are least likely to remember.

This guide covers why your own attention is so hard to observe, six small experiments you can start today with paper and a timer, and where an automatic record helps. One note up front: Dayflow, which publishes this article, is our product. It appears in one section near the end, followed by a section on when it is the wrong pick.

The short version

• Pick one question before you measure anything. “Where does my attention go after lunch?” beats “track everything.”
• Keep a paper tally of interruptions in two columns: the ones others caused and the ones where you drifted.
• Set a kitchen timer to ring about once an hour, and when it does, write what you are doing and whether you meant to be doing it.
• Before each task, guess how long it will take, then compare the guess with the clock.
• Spend fifteen minutes each Friday reviewing your notes, change one thing, and drop any metric you never look at.

Why is your own attention so hard to see?

Memory keeps the highlights. At the end of the day you remember the meeting that went badly and the bug you finally fixed. The twenty small detours between them leave almost no trace. So when you rebuild the day from memory, you get a neat story with the messy parts edited out.

Switching feels free. Opening a chat window takes a second, and it never feels like a decision. Many people find that getting back to where they were takes much longer than the switch itself. Because the cost shows up later, as a vague sense of “where did the afternoon go,” it rarely gets linked to the moment that caused it.

Hours and attention are different things. A calendar can show three hours blocked for writing. It cannot show whether you wrote for three hours or for forty minutes plus a lot of tab-checking. Most tracking tools count the first. What you probably care about is the second.

Measuring changes the thing you measure. Once you start counting interruptions, you will interrupt yourself a little less, at least for a few days. That is useful if your goal is to change. It just means your first week of notes is a slightly flattering picture, so don’t treat it as gospel.

Too much data gets ignored. The usual quantified self trap is collecting everything because it is possible. A log you never review is a chore, not a tool. The experiments below are deliberately small for that reason.

What should you measure first?

What to do. Write one question on an index card and keep it where you work. The question decides what you record and, just as important, what you ignore. Good questions are specific and a bit uncomfortable:

• “When during the day do I do my best thinking?”
• “How often do I leave the thing I meant to be doing?”
• “Do meetings eat my mornings, or does it only feel that way?”

If you have no idea where to start, a rough estimate helps. The where does my week go calculator gives a quick picture of how your hours split up on paper, and the gap between that and how the week feels is often a good first question.

An illustration. A designer suspects that messages ruin her afternoons. Her card reads: “Between 1 and 5, how many times do I leave the design file?” She ignores mornings, meetings and everything else for now.

How to tell after a week. You can answer your question in one sentence, even if the answer is “not what I expected.” If you can’t, the question was too broad. Narrow it and run another week.

Keep an interruption tally on paper

What to do. Put a card or sticky note next to your keyboard with two columns: pulled and drifted. Pulled is when someone or something else broke in, such as a message, a tap on the shoulder or a notification. Drifted is when you left on your own. Each time it happens, make a tick. If it costs nothing, add one word, like “email” or “news.”

The two columns matter because they call for different fixes. Pulled interruptions are about your setup and your colleagues. Drifted ones are about the task, your energy, or what was hard right before you left.

An illustration. By Tuesday evening the card shows four ticks under pulled and eleven under drifted. Most of the drift ticks sit after 2 p.m., and several have the word “stuck” next to them.

How to tell after a week. Ignore the totals and look for clusters. Do drift ticks bunch up at certain hours, or right after certain kinds of work? If you stopped ticking by Wednesday, the method is too fiddly. Make it easier, for example with tally marks only and the card stuck to the edge of your screen.

Use a kitchen timer to sample your attention

What to do. Instead of logging all day, take snapshots. Set a kitchen timer for somewhere between 45 and 75 minutes, and vary it so you can’t anticipate it. When it rings, write three things: what is in front of you, what you meant to be doing, and yes or no for whether they match. Then reset the timer and go back to work.

This works because it asks very little of you. You don’t have to notice the drift as it happens. The timer catches you wherever you are. If you want a fuller version of this idea, our guide on how to do a time audit on a Mac walks through a longer structured audit.

An illustration.

Time	On screen	Meant to be doing	Match?
9:52	Inbox	Proposal draft	No
11:04	Proposal draft	Proposal draft	Yes
12:10	News site	Lunch	Close enough
1:21	Team chat	Bug fix	No

How to tell after a week. You will have a few dozen snapshots. Group them by morning, early afternoon and late afternoon, and look at where the “no” answers fall. The gaps count too. If you kept missing the timer between 2 and 4, that tells you something about those hours.

How long do things really take?

What to do. Before starting a task, write down a guess for how long it will take. Note the start and finish times from a real clock, not from feel. Add a third column for the difference. Do this for every task over one week, including the small ones you would normally not bother with.

If you are curious how your sense of time compares with a clock before you start, the time estimation test is a short exercise for that. It is not a diagnostic, just a quick check.

An illustration. “Reply to the contractor: guessed 10 minutes, took 35.” “Write the summary: guessed 60 minutes, took 50.” “Quick look at the analytics: guessed 5, took 40.”

How to tell after a week. Look for the kinds of tasks where you are consistently off in the same direction. Many people find their big tasks are estimated reasonably well, while “quick” replies and checks are where whole afternoons go missing. Once you know which category slips, you can pad it on purpose when you plan.

Note your energy alongside your time

What to do. Attention is not only about where it goes but also about how much you have. At the end of each work block, or each time the sampling timer rings, add a number from 1 to 5 for how alert you felt. Don’t overthink it. A gut number is fine.

An illustration. A writer’s week shows mostly 4s and 5s between 8 and 11, then 2s right after lunch, and a small bump back to 3 around 4 p.m. Her drift ticks from the tally card line up almost exactly with the 2s.

How to tell after a week. Line up your energy numbers with time of day and with task types. If a clear high point shows up, protect it next week. Move a meeting out of it, or save your hardest task for it. If the numbers are flat and random, that is also an answer. Your attention may depend more on the task than on the clock.

Hold a fifteen-minute weekly review, ideally with a friend

What to do. On Friday, spread out the week’s cards and notes. Answer three questions in writing:

1. What surprised me?
2. What one thing will I change next week?
3. What will I stop measuring because I never looked at it?

Doing this with a friend who is running their own experiment helps more than it sounds. Saying “I drifted eleven times on Tuesday, mostly when I got stuck” out loud makes it concrete, and you are more likely to try the change you named. If you would rather keep a running written record, the daily work log template gives you a simple structure, and our guide to keeping a work journal covers how to make the habit stick.

An illustration. A developer’s review: “Surprised that meetings weren’t the problem. Drift after getting stuck was. Next week: when stuck, write the blocker on paper before switching windows. Stop tracking: total screen hours, never looked at it.”

How to tell after a week. After the first review you have made one change. After two or three, you should have dropped at least one metric and kept one that keeps teaching you something. If the review keeps getting skipped, shorten it to five minutes and one question.

Where seeing your actual day helps

Every experiment above has the same weak spot. It depends on you noticing and writing things down, usually at the moments your attention is somewhere else. The drift you didn’t notice never gets a tick.

An automatic record covers that gap. Dayflow is a free, MIT-licensed Mac app for macOS 14 or later. It records your screen and has AI write the day into a readable timeline, so you can answer where did my day go without rebuilding it from memory. Recordings and the timeline are stored on your Mac. With Local AI through Ollama or LM Studio, screenshot analysis stays on your Mac. If you choose your own cloud provider or Dayflow Pro ($20 a month), selected screenshots are processed off-device. How local and cloud processing differ explains the trade-offs. You can export a date range as Markdown from Settings → Export.

It works well next to paper. The timeline shows what was on screen, and your notebook holds intent and energy, which no screen record can see. AI summaries can miss or misread work, so treat them as a draft to check. If you are weighing other options, our guide to Mac time trackers covers the wider category.

The Dayflow details here come from its own documentation for version 2.2.0, reviewed on 2026-09-06. Dayflow publishes this article and is our product.

Where Dayflow is the wrong pick

You don’t work on a Mac. Dayflow is Mac only. If your work happens on Windows, Linux or a phone, a paper log and a kitchen timer will do more for you.

Your attention problem is off-screen. Dayflow sees only the screen. It knows nothing about thinking on a walk, sketching on a whiteboard, reading printouts or taking calls away from your desk. For energy, intent and off-screen work, the paper notebook wins outright.

You want to stop distractions, not see them. Dayflow has no website blocking. It shows you a pattern after the fact and cannot step in while you scroll. If prevention is the goal, a dedicated website blocker is the right tool.

You want a coach or a fix. Dayflow is a record. It doesn’t tell you what to change, set goals for you or hold you to them. The weekly review, and a friend who asks how it went, do that job better.

You need billing or team reporting. Dayflow has no invoices, payroll approvals or team reports. If your tracking is really about clients or a manager, see our guide to time tracking apps for freelancers on Mac.

Being recorded would change how you work. Some people feel watched even by their own tools, and some workplaces don’t allow screen recording on work machines. If either applies, stay with paper. Our piece on time tracking without surveillance goes into this further.

The bottom line

You can’t improve attention you can’t see, and you can’t see it by trying harder to remember. Start with one question, a card and a kitchen timer. Run the experiment for a week, review it on Friday, change one thing, and drop whatever you never look at.

If logging by hand keeps falling apart because you forget at the moments that matter, an automatic record of your screen can fill in what memory leaves out. Keep the paper anyway. The most useful information about your attention, such as what you meant to do and how you felt doing it, only you can write down.

Frequently asked questions

What is quantified self for work?

It means collecting simple data about your own working day so you can see patterns you would otherwise miss. That data covers when you focus, what pulls you away, and how long tasks really take. It does not need wearables or dashboards. A notebook, a clock and a regular review are enough to start. The goal is self-knowledge you can act on, not a performance score.

What should I track to understand my attention at work?

Track one thing tied to one question you actually care about. Good starting points are interruptions, split into ones that came from others and ones where you drifted on your own. Others are whether you were doing what you meant to do when a timer rang, and your energy level by time of day. Trying to track everything at once usually means you stop within two weeks.

How do I track my attention without an app?

Keep an index card next to your keyboard and make a tick each time you leave the task you meant to be doing. Set a kitchen timer to ring roughly every hour, and when it does, write what is in front of you and whether it matches your plan. Review the cards on Friday. Paper is quick, it works anywhere, and it captures intent, which software cannot see.

How long should I track my attention before I see patterns?

One working week is usually enough to notice something, such as a slump after lunch or a habit of checking messages when a task gets hard. Two or three weeks help you tell a real pattern from an odd week. Past that, keep tracking only if you are testing a specific change. Measuring for its own sake tends to fade, and that is fine.

Does tracking my attention change how I work?

Often, yes. Many people find that simply knowing they will make a tick makes them pause before switching tabs. That is useful if your goal is to work differently, but it can blur the picture of your normal habits. To get a more honest baseline, keep the method light and avoid judging the numbers during the first week. Save the judging for the review.

Can Dayflow block distracting websites?

No. Dayflow has no website blocking. It records what was on your screen and summarizes the day afterward, so it can show you a pattern but cannot stop you mid-scroll. If your main goal is to cut off certain sites during work hours, a dedicated website blocker is the better tool. Some people use a blocker for prevention and a record like Dayflow to check whether it worked.

Is a paper log better than an automatic tracker for attention?

For some things, yes. A paper log captures what you meant to do, how alert you felt, and work done away from the screen, and Dayflow sees none of those. An automatic tracker beats paper at catching the switches you never noticed and at filling in hours you forgot to log. Many people get the clearest picture by using paper for intent and energy and an automatic record for the rest.

Does Dayflow keep my screen recordings private?

Full screen recordings and the timeline are stored on your Mac. With Local AI through Ollama or LM Studio, screenshot analysis stays on your Mac too. If you choose your own cloud provider or Dayflow Pro, selected screenshots are processed off-device. Under the privacy policy, Pro deletes screenshots after processing and may keep Activity Data for sync. Your own provider has its own terms.

How much does Dayflow cost?

Dayflow is free ($0) and open source under the MIT license. It runs on macOS 14 or later and is Mac only. An optional Dayflow Pro plan costs $20 a month and manages the cloud analysis for you. You can also use the free app with Local AI on your own Mac, or connect your own cloud provider, whose charges and terms apply.

What is the difference between tracking time and tracking attention?

Time tracking records how long you spent on something, usually so you can bill clients or report hours. Attention tracking asks a different question: when you were at the task, were you really with it, and what pulled you away? Two hours logged on a report can hide a dozen trips to your inbox. Attention tracking cares about switches, intent and energy more than totals.
