Average refocus time after interruption (Gloria Mark)
Static blocklists don't work when your distractions are unpredictable.
I spent years trying every focus tool on the market. Freedom, Cold Turkey, SelfControl, HeyFocus. They all work the same way: you build a list of sites to block, start a timer, and hope for the best.
The problem is that work is contextual. YouTube is a tutorial at 10am and a rabbit hole at 2pm. The same URL, two completely different contexts. No list can know the difference.
And then there's the other problem nobody talks about: fragmentation. You're not on Twitter. You're bouncing between five legitimate things, touching everything and finishing nothing.
Hugo uses AI to evaluate every tab you open against the goal you set for your session. It doesn't need a list. You tell it what you're working on, and it handles everything else.
What real people say about focus and distraction
"Opening Reddit or Hacker News was the path to a surge of dopamine. Whereas getting down to work didn't have the same surge."
swalsh, Hacker News
"When the habit kicks in to ctrl+T, type a social media URL, hit enter... before your conscious mind even takes over."
Baptiste Gautier, Trustpilot
"I was busy all day and I have nothing to show for it."
Common refrain across r/productivity
"Standard website blockers are blunt instruments in a world that requires surgical precision."
PixieBrix blog
"The distraction being contextual part really resonates with me."
marcobelsia, Hacker News
How I evaluate every focus tool I review
Install and use it daily for at least one full work week
Not a 20-minute test. A real week of real work.
Test across browsers and desktop apps
Chrome, Safari, and macOS apps.
Attempt every known bypass
Private browsing, browser switching, app force-quit, VPN, DNS changes.
Verify every claim against primary sources
If a study is cited, I read the original paper.
Disclose limitations honestly
Every tool has weaknesses, including Hugo.
macOS productivity
Building native Mac tools with Swift and SwiftUI. Deep system integration, not cross-platform compromise.
Focus and distraction research
Peer-reviewed studies on context switching, attention residue, and how long it really takes to refocus (Mark et al., 2005).
AI focus tools
Using Gemini 2.5 Flash to evaluate browser tabs contextually. The same URL, allowed or blocked depending on the session goal.
ADHD productivity
Environmental design over self-discipline. Tools that work with how your brain actually operates, not against it.
Focus app comparisons
Honest, data-backed reviews of Freedom, Cold Turkey, Opal, SelfControl, and every other Mac focus tool.
Deep work
Practical implementation of Cal Newport's framework on macOS. Focus modes, notification management, and session structure.

No task left behind? Examining the nature of fragmented work

Workers were interrupted or switched tasks roughly every 3 minutes, with an average of 2.3 intervening tasks before returning to the original work.
The cost of interrupted work: More speed and stress
Mark, Gudith, and Klocke (2008). Proceedings of CHI 2008.
Interrupted workers completed tasks faster but at the cost of significantly higher stress, frustration, and mental workload.

The median duration of online screen focus was 40 seconds.
Why is it so hard to do my work?
Leroy (2009). Organizational Behavior and Human Decision Processes.
Attention residue from incomplete tasks persists after switching, reducing cognitive performance on the next task.
Checking email less frequently reduces stress

Limiting email to 3 checks per day significantly reduced daily stress compared to unlimited checking.

Hugo vs the alternatives
Try what I built.
Hugo is free to download. Set your goal, start a session, and see what happens when your Mac is finally on your side.

The focus app that thinks for you.
Hugo sits between you and distraction. It hides your apps, locks down your browser, and uses AI to silently decide if what you're opening is actually work - so you never have to burn willpower again.
