YOUR DESK-TOP AI FOCUS COACH
Measure the quality of focus,
not just study time.
A palm-sized cube that understands focus through the eyes —
and never stores a single frame of video.
WATCH · 80 SEC
See it in 80 seconds
Skip the long read — one short video shows exactly what concentration-cube does.
Six hours at the desk ≠ six hours of studying
Plenty of tools track study time. None of them tell you whether that time was actually focused.
Study timer apps
Track seat time only — and the phone itself is a distraction.
Camera study rooms
A human watches a video feed. No objective data, full face exposure.
Research eye trackers
Precise, but thousands of dollars — not for the home.
EEG headbands
Too uncomfortable for kids to wear through real study sessions.
Nothing measured the quality of focus — contact-free, video-free, at a consumer price. That's the gap we fill.
HOW IT WORKS
Place it by the book. The report arrives.
During measurement all lights turn off — the child forgets it's there.
Pick a session
20, 30, or 40 minutes in the app.
Place beyond the book
Centered past the book's top edge, 30–60cm from the face.
30-second calibration
Glance at five points and you're set.
Automatic report
When the session ends, the focus report lands in the app.
PRODUCT DESIGN
Designed to sit quietly on a child's desk
A double-hinged stand for any angle, an Aroma Bay for scent cartridges, and a single USB-C connection — designed to look like stationery, not a surveillance camera.
FOCUS REPORT
After each session, you'll know:
- Focus retention — how much of the session was truly on the page
- Recovery — how quickly attention returned after drifting
- Fatigue signals — drowsiness patterns emerging late in the session
- Focus rhythm — when focus breaks down, and when it peaks
- Growth trend — the score that matters is vs. your own past sessions, not vs. others
Not a camera that watches.
A coach that stays beside.
Not a single frame of video is ever stored or transmitted.
The server has no capability to receive video at all.
Streams video to servers — a leak is always possible.
There is structurally no video to leak.
BEYOND MEASURING
Beyond measuring — toward better focus
One device measures, helps improve, then measures again to verify.
Start & boost routine
Before studying, 60–75 seconds of light-ring rhythm align the eyes — then a short boost with eyes closed, focusing only on sound.
Gentle return cue
Only when drifting lasts over a minute, a soft chime rings once — capped at 3 per session. When your child is sleepy, it suggests rest, not "focus!".
Sound personalization
We don't claim white noise works for everyone. We compare silence and sounds against actual focus scores. The library keeps growing — no app update needed.
Sleep routine
A wind-down for the night after studying — light stretching, breathing, and a guided meditation as the music slowly fades. Choose the short or the 5-minute version.
Aroma routine (optional)
Unscented by default. Optional cartridges become a "study mode" cue — allergy screening comes first.
Quiet ending
No sound, no vibration, no popup when a session ends. Just a green light blinking slowly for 15 seconds — never breaking the flow that follows.
We never claim "it works for everyone." We verify what works for your child — in numbers.
WHY TRUST US
Olympic-level focus care, on your child's desk
Designed and built by a physician who manages focus and performance for national-team athletes.
Built by a physician
A Seoul National University Hospital–trained specialist and acting national-team chief medical officer develops the algorithms and app himself — someone who knows what physiological signals do and don't tell you.
Hospital IRB validation
Before launch, a hospital IRB–approved validation study scores the device against ground truth: participants record when they truly focused, zoned out, or did something else.
Eye-safety by design
Dual limits on infrared output, automatic cutoff when too close, and IEC 62471 photobiological safety assessment before mass production.
OUR MOAT
Technology no one can follow — a self-evolving engine
Hardware can be imitated; this cannot. Every time a validation-study "answer key" arrives, AI revises its own judgment rules — and only changes that pass an exam it has never seen are adopted. We call it Live Evolution.
Answer key
Participants record when they truly focused
Error notebook
Mismatches with the device pile up
AI revises
AI reads the errors and edits the rules itself
Hidden exam
Re-tested on data it has never seen
Passers only
No metric may regress; everything is logged
