Focus Zen

Not a timer. Not a blocker.

Half your focus time is leaking — and you can’t feel it.

Research puts mind-wandering at 47% of waking hours. Focus Zen watches your attention through your webcam and pulls you back within seconds of drifting — so a 2-hour session actually produces 2 hours of work.

Sound Familiar?

You’re not alone. This is what working blind to your own attention looks like.

  • •Re-reading the same paragraph 5 times
  • •Cramming because focus sessions fall apart

Remote Workers

"Working from home with constant distractions"

  • •Slack pings every 3 minutes
  • •Ending the day wondering where it went

Freelancers

"Juggling multiple clients and deadlines"

  • •Task-switching killing your momentum
  • •Working late to make up for lost focus

It’s not a discipline problem. It’s a focus visibility problem.

You can’t fix what you can’t see.

How it works

From webcam to focus coach in under a minute.

Two clicks: Focus Zen learns where your work lives — your screen or your book. Runs in your browser; nothing uploads.

A running focus session: the ensō circle drawing itself next to the live focus stats

02Work

An ensō circle draws itself while you stay in. Your live focus curve runs beside it.

A drift moment: the session view with a notification nudging you back to work

Focus Zen

Drifting — come back to it.

03Get caught drifting

The moment your mind wanders, a soft sound and a notification bring you back — seconds after drift, not ~23 minutes later.

04Debrief

Focus %, drift count, longest streak — and the ensō your attention drew. Yours to keep or share.

Every session becomes memory

A single session shows you today — focus %, drifts, your rhythm. A week of sessions shows you you: which hours you’re focusable, what breaks you, what your best days have in common.

Why alternatives fail

Pomodoro timers don’t prevent distractions. App blockers don’t stop mind wandering. Here’s how active attention tracking compares.

Focus time reclaimed per week~2–5 h †——

† Estimate from published averages — mind-wandering occupies ~47% of waking hours (Killingsworth & Gilbert, 2010); an interruption costs ~23 minutes to refocus (Mark et al., 2008) — assuming ~2 h of deep work daily. Your first debrief shows your real number.

Pomodoro timers…

…count time. They can’t tell a focused 25 minutes from a distracted one. A timer that doesn’t see focus is just a clock.

App blockers…

…guard the wrong door. The distraction that costs the most isn’t an app — it’s the drift you never notice.

Private by architecture

The camera is the product’s eyes. Never ours.

Video never leaves your device

Frames are analyzed in your browser's memory and discarded. No upload path exists in the code.

Only numbers sync

Focus percentages and timestamps — that's all your account stores. Want it gone? One email, and it's deleted.

Don't take our word for it

Run a session with DevTools open: zero video requests. Anyone can verify this claim, in any browser, right now.

Questions, answered

It watches for you, locally: your camera feed is processed inside your browser and discarded frame by frame. Nothing is recorded, nothing is uploaded. Close the tab and it’s gone.

Numbers only: focus percentages, timestamps, session stats — the things your debrief is made of. Never images, never video. Want your data deleted? One email, done.

Gaze estimation is accurate to roughly 1.4–2°, which is plenty to tell “on the work” from “drifted away”. What it can’t do: read your mind. If you stare at the screen while daydreaming, some drifts pass unseen. It’s a mirror, not a mind reader — and it catches far more than nothing, which is what you have now.

Most glasses, yes. Very low light or strong backlight degrades tracking; calibration will tell you before a session starts.

Not for the attention test. A free account (no card) gives you 5 camera sessions a week, the full debrief after each, and today’s stats. Your past sessions are saved to your account from day one — Premium is what turns them into patterns and history.

No. Focus Zen is a focus-support tool, not a medical device. It was built for people traditional focus tools failed — if that’s you, it may help you see your attention clearly. It makes no medical claims.

Cancel anytime: email contact@focuszen.io from your account address and we cancel the same day, no questions, no retention flow. Every paid plan has a 14-day money-back guarantee, same address.
