How to review your deep work without a distraction blocker

Distraction blockers work while they are on. The moment you disable one to “quickly check something,” you are back where you started - and there is no record of what happened. A deep-work review is the other approach: instead of policing yourself in the moment, you look at an honest record of your day and adjust. Blockers are enforcement; reviews are feedback.

What a deep-work review needs

To review your focus you need to know, truthfully, three things:

1. When were the long unbroken stretches? Deep work shows up as 60-plus-minute blocks on a single task.
2. What actually broke them? Slack, email, a “quick” YouTube detour - the breaks you do not remember are the ones that matter.
3. What did the fragmented time cost? Six hours at the desk that produced two hours of real work is the pattern to catch.

Manual timers cannot answer these questions because you do not start a timer before getting distracted. Nobody logs “aimless twitter, 2:15-2:40.”

The automatic version

Dayflow records your Mac’s screen at one frame every 10 seconds and has AI write the day into a readable timeline - including the parts you would not have logged yourself. It can tell “researching on YouTube” from “watching cat videos,” which is exactly the distinction a focus review needs. It is free, open source, and 100% local: recordings never leave your computer.

The weekly review, ten minutes on Friday:

1. Scan the week’s timelines for your longest unbroken blocks. When did they happen? (Most people find a consistent window - often mid-morning.)
2. Count the interruptions inside what you intended as focus time. Name the top offender.
3. Compare intention to record: the meeting-free Tuesday afternoon you planned - what did it actually contain?
4. Set one change for next week. Just one: “Slack closed until 11am.”

Why this beats blocking

A blocker treats the symptom in the moment and teaches you nothing about the pattern. A review compounds: after three weeks you know your genuine focus windows, your actual top distraction (rarely the one you would have guessed), and whether your one-change-per-week is working. Some people run both - a blocker during their protected window, the review to decide where the window should be. If you want the blocker too, RescueTime and Cold Turkey do that job well; Dayflow deliberately does not block anything.

Honest limitations

Dayflow observes the screen, so thinking time away from the keyboard is invisible to it. It is Mac-only. And a review only works if you actually look at it - the Friday calendar reminder is part of the system.

Start with Dayflow (free, MIT-licensed, macOS 14+), let it run for a week, and do your first review. The first one is usually uncomfortable. That is the point.
